NET CONTENTS 2.5 GAL

Picloram is a chemical which can travel (seep or leach) through soil and under certain conditions has the potential to contaminate groundwater which may be used for irrigation and drinking purposes. Users are advised not to apply picloram where soils have a rapid to very rapid permeability throughout the profile (such as loamy sand to sand) and the water table of an underlying aquifer is shallow or to soils containing sinkholes over limestone bedrock, severely fractured surfaces, and substrates which would allow direct introduction into an aquifer. Your local agricultural agencies can provide further information on the type of soil in your area and the location of groundwater.

Precautionary Statements Hazards to Humans and Domestic Animals

CAUTION

Causes Moderate Eye Irritation

Avoid contact with eyes or clothing. Prolonged or frequent repeated skin contact may cause allergic skin reactions in some individuals.

This chemical can contaminate surface water through spray drift. Under some conditions, picloram may also have a high potential for runoff into surface water (primarily via dissolution in runoff water). These include poorly draining or wet soils with readily visible slopes toward adjacent surface waters, frequently flooded areas, areas over-laying extremely shallow ground water, areas with in-field canals or ditches that drain to surface water, areas not separated from adjacent surface waters with vegetated filter strips, and areas over-laying tile drainage systems that drain to surface water.

Personal Protective Equipment (PPE)

Applicators and other handlers must wear:

• Long-sleeved shirt and long pants • Chemical-resistant gloves made out of any waterproof material • Shoes plus socks

Follow manufacturer's instructions for cleaning/maintaining PPE. If no such instructions for washables exist, use detergent and hot water. Keep and wash PPE separately from other laundry.

Engineering Controls: When handlers use closed systems, enclosed cabs, or aircraft in a manner that meets the requirements listed in the WPS (40 CFR 170.240(d)(4-6)), the handler PPE requirements may be reduced or modified as specified in the WPS.

Use Precautions

Storage and Disposal

• To prevent damage to crops and other desirable plants,

read and follow all directions and precautions on this label and container before using.
Do not contaminate water, food, fertilizer or feed by storage or disposal. Open dumping is prohibited. Pesticide Storage: Store in original container only. In case of leak or spill, contain material with absorbent materials and dispose as waste. Pesticide Disposal: Pesticide, spray mixture, or rinsate that cannot be used according to label instructions must be disposed of according to applicable Federal, state or local procedures.

• Use caution when treating areas adjacent to susceptible

and desirable species to avoid root uptake and possible injury when using Tordon K or other soil active herbicides.

• Applications of Tordon K within the root zone of desirable trees should not be made unless injury can be

tolerated. Caution should be exercised when treating high density of stems adjacent to desirable trees with roots in the treatment zone. Trees adjacent to or in a treated area can occasionally be affected by root uptake of Tordon K. Severe injury or plant death can occur if used near conifers, roses, leguminous trees such as locusts, redbud, mimosa, and caragana, or other sensitive species.
Container Handling: Nonrefillable container. Do not reuse or refill this container. Offer for recycling if available. Triple rinse or pressure rinse container (or equivalent) promptly after emptying. Triple rinse as follows: Empty the remaining contents into application equipment or a mix tank and drain for 10 seconds after the flow begins to drip. Fill the container 1/4 full with water and recap. Shake for 10 seconds. Pour rinsate into application equipment or a mix tank or store rinsate for later use or disposal. Drain for 10 seconds after the flow begins to drip. Repeat this procedure two more times. Pressure rinse as follows: Empty the remaining contents into application equipment or a mix tank and continue to drain for 10 seconds after the flow begins to drip. Hold container upside down over application equipment or mix tank or collect rinsate for later use or disposal. Insert pressure rinsing nozzle in the side of the container, and rinse at about 40 psi for at least 30 seconds. Drain for 10 seconds after the flow begins to drip.

• Conifer Planting Intervals. Conifer plantings after

treatment with Tordon K vary by region. Pines planted sooner than six months after treatment with Tordon K may be injured in the South or west of the Cascade Mountains. Other conifers, west of the Cascade Mountains, may be injured if planted sooner than 8 to 9 months after treatment. For all conifers, the waiting period between treatment and planting is 11 to 12 months in the area between the Cascade and Rocky Mountains and 8 to 9 months in the lake States and Northeastern U.S. Southern pines are more tolerant and can be planted as early as three months after a fall application of Tordon K at maximum labeled rates.

to fall onto banks or bottoms of irrigation ditches, either dry or containing water, or other channels that carry water that may be used for irrigation or domestic purposes.

• Do not apply to areas that may be rotated to any

broadleaf crop and do not rotate to food or feed crops

on treated land if they are not registered for use with picloram until an adequately sensitive bioassay or chemical test shows that no detectable picloram is present in the soil.
• Do not use on flood or sub-irrigated land or areas irrigated by periodic flooding or a shallow water table.

• Do not spray if the loss of forage legumes, including

clover cannot be tolerated. Tordon K may injure or kill

legumes. New legume seedlings may not grow for several

  • years following application of this herbicide.
  • • Do not use manure from animals grazing treated areas or

feeding on treated hay on land used for growing broadleaf crops, ornamentals, orchards or other susceptible, desirable plants. Manure may contain enough picloram to cause injury to susceptible plants.

• Do not treat snow or frozen soil where runoff could damage sensitive plants.

• Do not apply this product to lawns, turf, ornamental

plantings, urban walkways, driveways, tennis courts, golf courses, athletic fields, commercial sod operations, or other high-maintenance, fine turfgrass areas, or similar areas.

• Do not use treated plant material including grass, hay, straw, wood chips, bark dust, or saw dust for composting

or mulching of susceptible broadleaf plants or crops.

• Do not apply Tordon K on residential or commercial lawns or near ornamental trees and shrubs. Untreated

trees can occasionally be affected by root uptake of herbicide through movement into the topsoil or by excretion of the product from the roots of nearby treated trees.
• Do not transfer livestock from treated grazing areas (or if feeding on treated hay) onto sensitive broadleaf crop areas without first allowing 7 days of grazing on an untreated grass pasture (or feeding of untreated hay). Otherwise, manure and urine may contain enough picloram to cause injury to sensitive broadleaf plants.

• Do not move treated soil to areas other than sites for

which Tordon K is registered for use. Also, do not use treated soil to grow plants for which use of Tordon K is not registered until an adequately sensitive bioassay or

chemical test shows that no detectable residue of picloram is present in the soil.

• Do not use manure from animals that have grazed forage

or eaten hay harvested from treated areas within the previous 7 days, in compost, mulch or mushroom spawn.

• Do not spread manure from animals that have grazed or

consumed forage or eaten hay from treated areas within the previous 7 days on land used for growing susceptible broadleaf crops.

• Do not plant a broadleaf crop (including soybeans, sunflower,

tobacco, vegetables, field beans, peanuts, and potatoes) in fields treated with manure from animals that have grazed forage or eaten hay harvested from Tordon K treated areas until an adequately sensitive field bioassay is conducted to determine that the picloram concentration in the soil is at level that is not injurious to the crop to be planted.

• Do not make application when circumstances favor movement from treatment site through drift of spray

particles or runoff. Applications made during periods of intense rainfall, to soils saturated with water, surfaces paved with materials such as asphalt or concrete, or soils through which rainfall will not readily penetrate may result in runoff and movement of Tordon K. Injury to crops may result if treated soil is washed, or moved onto land used to produce crops sensitive to picloram. Exposure to Tordon may injure or kill susceptible crops and other broadleaf plants, such as grapes, soybeans, tobacco, and sensitive ornamentals plants and trees.

• To promote herbicide decomposition, plant residues should be evenly incorporated in the surface soil or burned. Breakdown

of picloram in plant residues or manure is more rapid under warm, moist soil conditions and may be enhanced by supplemental irrigation.

• Do not use spray equipment used to apply Tordon K for

other applications to land planted to, or to be planted to susceptible crops or desirable sensitive plants, unless it has been determined that all phytotoxic residue of this herbicide has been removed by thorough cleaning of equipment.

No attempt at phylogenetic reconstruction has been made since recent revisions in circumscription, and previous reconstructions did not include a good representation of species. A new molecular survey is thus needed. Methods Phylogenetic analyses were conducted using sequences of the internal transcribed spacers (ITS) 1 and 2 and the 5.8S gene. Parsimony and Bayesian approaches were used. Key Results A close correlation between geography and the phylogenetic tree based on ITS sequences was found in all the analyses, with three main groups being resolved: (1) comprising the most widely distributed circum- Mediterranean/Eurosiberian sections; (2) the western Mediterranean sections; and (3) the eastern Mediterranean and Irano-Turanian sections. The results show that the sectional classification in current use needs major revision, with many old sections being merged into larger ones.

    New Perspectives of Purple Starthistle (Centaurea Calcitrapa) Leaf Extracts

    Dimkić et al. AMB Expr (2020) 10:183 https://doi.org/10.1186/s13568-020-01120-5 ORIGINAL ARTICLE Open Access New perspectives of purple starthistle (Centaurea calcitrapa) leaf extracts: phytochemical analysis, cytotoxicity and antimicrobial activity Ivica Dimkić1*† , Marija Petrović1†, Milan Gavrilović1, Uroš Gašić2, Petar Ristivojević3, Slaviša Stanković1 and Peđa Janaćković1 Abstract Ethnobotanical and ethnopharmacological studies of many Centaurea species indicated their potential in folk medi- cine so far. However, investigations of diferent Centaurea calcitrapa L. extracts in terms of cytotoxicity and antimi- crobial activity against phytopathogens are generally scarce. The phenolic profle and broad antimicrobial activity (especially towards bacterial phytopathogens) of methanol (MeOH), 70% ethanol (EtOH), ethyl-acetate (EtOAc), 50% acetone (Me2CO) and dichloromethane: methanol (DCM: MeOH, 1: 1) extracts of C. calcitrapa leaves and their poten- tial toxicity on MRC-5 cell line were investigated for the frst time. A total of 55 phenolic compounds were identifed: 30 phenolic acids and their derivatives, 25 favonoid glycosides and aglycones. This is also the frst report of the pres- ence of centaureidin, jaceidin, kaempferide, nepetin, favonoid glycosides, phenolic acids and their esters in C. calci- trapa extracts. The best results were obtained with EtOAc extract with lowest MIC values expressed in µg/mL ranging from 13 to 25, while methicillin resistant Staphylococcus aureus was the most susceptible strain. The most susceptible phytopathogens were Pseudomonas syringae pv. syringae, Xanthomonas campestris pv. campestris and Agrobacte- rium tumefaciens. The highest cytotoxicity was recorded for EtOAc and Me2CO extracts with the lowest relative and absolute IC50 values between 88 and 102 µg/mL, while EtOH extract was the least toxic with predicted relative IC 50 value of 1578 µg/mL.

    Purple Starthistle Centaurea Calcitrapa Other Common Names

    Purple starthistle Other common names: red starthistle USDA symbol: CECA2 Centaurea calcitrapa ODA rating: A and T Introduction: Purple starthistle is native to the Mediterranean region, southern Europe and northern Africa. It is well adapted to a range of temperature and moisture regimes. Its potential impact on agriculture, wildlife and recreation would be significant. Distribution in Oregon: In Oregon, purple starthistle was first detected in Clackamas County and this site has been monitored and treated since 1993. A 2010 survey failed to locate any surviving plants. In 2009, a new infestation was discovered in Wheeler County. The Wheeler County site is receiving annual monitoring and treatment leading to eradication. Description: Purple starthistle is actually a heavily armored knapweed species and not classified as a true thistle. It can function as an annual or biennial depending on moisture conditions. Seedlings will sprout in the fall or early spring forming spiny rosettes in May and June. Blooming continues from midsummer through fall as the plant grows 1 to 6 feet tall. To conserve moisture the plant is covered in fine hairs, with narrow linear leaves retarding moisture loss. Flower heads are purple and arrayed with straw-colored spine-like bracts over 1 inch in length. Seeds are not plumed, the distinguishing factor between this plant and Iberian starthistle. Impacts: Closely resembling Iberian starthistle, both invasive species have the ability to adapt to a variety of climactic conditions. They are extremely competitive along roadsides and in low-rainfall rangeland, as well as in higher rainfall pastures, where they displace valuable forage. The sharp spines deter grazing animals or wildlife movement and their access to forage.

    Purple Starthistle Fact Sheet

    Purple Starthistle Fact Sheet Centaurea calcitrapa Asteraceae Family Barry Rice, sarracenia.com, Bugwood.org D. Walters and C. Southwick, Table Grape Weed DPI Victoria Disseminule ID, USDA APHIS ITP, Bugwood.org Distinguishing Features: Flowers: The flowers are purple and 0.6 to 1 inches in diameter. Twenty-five to 40 florets (small flowers) make up each flower head. Underneath the flower are spine-tipped bracts that are greenish or straw-colored. Seeds: The seeds are oblong and 2.5-3.5 mm long. They are white and often streaked with brown. Leaves: The leaves are alternate, with deeply divided lower leaves and narrow and undivided upper leaves. The leaves are five to eight inches long and have dots of resin on their surfaces. Flowering Time: The plant produces long stems in spring and early summer. It flowers from June through November. Life cycle: Purple Starthistle can live as an annual in extremely favorable conditions, but most often lives as a biennial. Impacts: ➢ Purple Starthistle can quickly displace native flora in disturbed areas due to its rapid growth and seed production. ➢ Purple Starthistle is unpalatable to grazing animals and rapidly degrades the forage quality in any infested areas. ➢ With thicker and stronger spines than its relatives, Purple Starthistle poses a threat of injury to both humans and animals moving through infested areas. K. Mosbruger, SLCO Weed Control Program Control: ➢ Small infestations of Purple Starthistle can be effectively controlled by manually pulling and disposing of plant remains. Plants should be cut at least 2 inches below the surface. ➢ There are no effective biocontrol agents currently approved for use in the US to control Purple Starthistle.

    Natural History Studies for the Preliminary Evaluation of Larinus Filiformis (Coleoptera: Curculionidae) As a Prospective Biolog

    POPULATION ECOLOGY Natural History Studies for the Preliminary Evaluation of Larinus filiformis (Coleoptera: Curculionidae) as a Prospective Biological Control Agent of Yellow Starthistle 1 2 3 4 L. GU¨ LTEKIN, M. CRISTOFARO, C. TRONCI, AND L. SMITH Faculty of Agriculture, Plant Protection Department, Atatu¨ rk University, 25240 TR Erzurum, Turkey Environ. Entomol. 37(5): 1185Ð1199 (2008) ABSTRACT We studied the life history, geographic distribution, behavior, and ecology of Larinus filiformis Petri (Coleoptera: Curculionidae) in its native range to determine whether it is worthy of further evaluation as a classical biological control agent of yellow starthistle, Centaurea solstitialis (Asteraceae: Cardueae). Larinus filiformis occurs in Armenia, Azerbaijan, Turkey, and Bulgaria and has been reared only from C. solstitialis. At Þeld sites in central and eastern Turkey, adults were well synchronized with the plant, being active from mid-May to late July and ovipositing in capitula (ßowerheads) of C. solstitialis from mid-June to mid-July. Larvae destroy all the seeds in a capitulum. The insect is univoltine in Turkey, and adults hibernate from mid-September to mid-May. In the spring, before adults begin ovipositing, they feed on the immature ßower buds of C. solstitialis, causing them to die. The weevil destroyed 25Ð75% of capitula at natural Þeld sites, depending on the sample date. Preliminary host speciÞcity experiments on adult feeding indicate that the weevil seems to be restricted to a relatively small number of plants within the Cardueae. Approximately 57% of larvae or pupae collected late in the summer were parasitized by hymenopterans [Bracon urinator, B. tshitsherini (Braconidae) and Exeristes roborator (Ichneumonidae), Aprostocetus sp.
