Some, such as parasitic wasps and ground beetles, are in fact beneficial insects that feed on the pests and reduce pest population and damage. Therefore, it is important to identify insects found on turfgrass correctly. An effective integrated pest management (IPM) program takes into consideration the biology, ecology, environment impacts, and all available treatment options. An IPM system is not difficult to adopt. Unbeknown to most turfgrass professionals, they are already utilizing some of these elements in making pest management decisions. Insecticide efficacy can be reduced by many environmental and biological factors. Water pH outside the suitable range can quickly degrade insecticides. Some insecticides may persist longer in clay than in sandy loam. Some insecticides may need irrigation after application to penetrate the soil and kill the insects that live underground. Insects may also develop resistance to one group of insecticides if the same group is applied to the same insect population repeatedly. In order to delay the development of insecticide resistance, avoid using insecticides from same mode of action or IRAC group number repeatedly. To assist in the decision to rotate insecticides, an IRAC table is included in this guide. Ants (nuisance ants and red imported fire ants): A large number of ant mounds can interfere with the play on the greens. RIFA is also a medical concern because of their stings. Monitoring: The small mounds made by the nuisance ants on the greens and the large mounds made by the RIFA along the periphery are the tell-tale signs. Treatment: Most ants can be treated by one of the three methods: individual mound treatment, broadcast granules of baits or long-residual toxicants, and a combination of the two methods. Billbug: Adults feed on the leaf blades and deposit eggs in the stem. The

  • Card Games for Individuals
    Card Games for individuals Patience The game is played using a tableau of seven columns. Running from left to right, the first column contains one card, the second contains two, the third three, etc. In each column, the top card should be face up and the rest face down. Deal by placing one card, face up, on the table in front of you then, to this card’s right, six more face down. Repeat this row by row, dealing one less card each time. As well as the face-up cards in the tableau, you’ll work with every third card in the remaining pack, one at a time. Move through the pack by taking three cards from the top and turning them over, creating a new face-up pile. When you’ve passed through the deck, turn it over and start again. In the tableau, a card from the pack may be placed on another card that is one rank higher and of an alternate colour. An eight of hearts, for example, may be placed on either a nine of spades or a nine of clubs - both black suits. Sequences of grouped cards can be moved around according to the same rules as individual cards. Whenever you free up a face-down card on a tableau column, turn it over. If a column is emptied, you can shift any card or sequence into it. If an ace comes into play, position it face up above the tableau, thus beginning a foundation. Foundations are suited and built from ace to king.

  • Historical Use of Lead Arsenate and Survey of Soil Residues in Former Apple Orchards in Virginia
    HISTORICAL USE OF LEAD ARSENATE AND SURVEY OF SOIL RESIDUES IN FORMER APPLE ORCHARDS IN VIRGINIA by Therese Nowak Schooley Thesis submitted to the faculty of the Virginia Polytechnic Institute and State University in partial fulfillment of the requirements for the degree of MASTER OF SCIENCE IN LIFE SCIENCES in Entomology Michael J. Weaver, Chair Donald E. Mullins, Co-Chair Matthew J. Eick May 4, 2006 Blacksburg, Virginia Keywords: arsenic, lead, lead arsenate, orchards, soil residues, historical pesticides HISTORICAL USE OF LEAD ARSENATE AND SURVEY OF SOIL RESIDUES IN FORMER APPLE ORCHARDS IN VIRGINIA Therese Nowak Schooley Abstract Inorganic pesticides including natural chemicals such as arsenic, copper, lead, and sulfur have been used extensively to control pests in agriculture. Lead arsenate (PbHAsO4) was first used in apple orchards in the late 1890’s to combat the codling moth, Cydia pomonella (Linnaeus). The affordable and persistent pesticide was applied in ever increasing amounts for the next half century. The persistence in the environment in addition to the heavy applications during the early 1900’s may have led to many of the current and former orchards in this country being contaminated. In this study, soil samples were taken from several apple orchards across the state, ranging from Southwest to Northern Virginia and were analyzed for arsenic and lead. Based on naturally occurring background levels and standards set by other states, two orchards sampled in this study were found to have very high levels of arsenic and lead in the soil, Snead Farm and Mint Spring Recreational Park. Average arsenic levels at Mint Spring Recreational Park and Snead Farm were found to be 65.2 ppm and 107.6 ppm, respectively.

We sprayed and sprayed, but they always came back. Now we under- stand there are better methods and products that really work” Environmental Health Watch Did you know...? ■ Many pesticides for home use are toxic? ■ There are alternative pest management methods that limit the use of toxic substances? ■ Mice, cockroaches, and cockroach "dust” can trigger asthma attack? What is it? Integrated pest management (IPM) is a way to remove pests, like cock- roaches, mice, and rats from a home. IPM is a common sense approach that: ■ Denies pests food, water, shelter and a way to enter the home. ■ Uses baits and powders, such as gel baits, traps and borate powder. Why use IPM? ■ IPM is safer. IPM does not use as many harmful pesticides as traditional pest control. - Avoiding pesticides is especially important in homes. Pesticides can contain long lasting, toxic chemicals or lung irritants that cause asthma attacks. Children are among those most vulnerable to exposure. IPM strategies apply pesticides only as needed and use the least hazardous pesticides to control pests. continued on back www.hud.gov/offices/lead U.S. Department of Housing and Urban Development SAFE PEST CONTROL Office of Healthy Homes and Lead Hazard Control Non-toxic traps can be part of an IPM strategy. If needed, call a pest control professional who uses IPM practices. If you have taken all the steps described above and still have a pest problem, you may need a professional to help.

  • Who Needs Chlorpyrifos and Why (By Crop)?
    1 WHO NEEDS CHLORPYRIFOS AND WHY (BY CROP)? EXCERPTS OF COMMENTS SUBMITTED TO EPA AT EPA-HQ-OPP-2015-0653 GENERAL “Consumers I have visited with that do not have any ag background are easily swayed into the belief that farmers are polluting the environment and recklessly applying chemicals. Truth is our farmers are professionals and with today’s pricing cannot afford to be over- or misapplying inputs that affect their bottom lines…. I strongly suggest that you…allow producers of the world’s food source to continue using the product chlorpyrifos.” – North Dakota farmer. “Many food crop industries in the Pacific Northwest are concerned about the impacts to pest management based on EPA’s proposed tolerance revocation of chlorpyrifos, including several minor crop groups with limited pesticide options. These industries include processed vegetables, strawberry, grass seed, mint, and cranberry. For many of these industries, chlorpyrifos has unique properties that make it an essential part of their Integrated Pest Management program. It is also an important tool for resistance management. Several of these industries have conducted research to identify effective alternatives to chlorpyrifos, but currently there aren’t viable alternatives that match the efficacy and low risk of this product for managing a number of critical pests…. A revocation of all chlorpyrifos tolerances would eliminate a number of low-risk, critical uses in cases where few alternatives exist at present, and in many cases those alternatives (neonicotinoids, pyrethroids) would be less efficacious, more expensive and have greater impacts on nontarget species including pollinators and beneficial insects. Further, the economic impacts based on resulting crop damage would be substantial.” – Oregon State University Agronomist.

  • Chlorpyrifos, Part 1: Toxicology
    JOURNAL OF PESTICIDE REFORM/ WINTER 1994 • VOL.14, NO. 4 ■ INSECTICIDE FACTSHEET CHLORPYRIFOS, PART 1: TOXICOLOGY The broad spectrum organophosphate insecticide chlorpyrifos is the most widely used insecticide in the U.S. Total use is estimated at almost 30 million pounds per year. Like all organophosphate insecticides, chlorpyrifos affects the nervous system by inhibiting an enzyme that is important in the transmission of nerve impulses. Symptoms of acute poisoning include headache, nausea, muscle twitching, and convulsions. Chlorpyrifos poisonings are reported to state and federal agencies more often than poisonings of almost every other insecticide. In both laboratory animals and humans, chlorpyrifos can also cause delayed effects on the nervous system. Some effects have been measured years after exposure. Human birth defects have been associated with exposure to chlorpyrifos products. In pregnant laboratory animals, chlorpyrifos exposure caused fetal death. Pups that did survive were smaller pups and did not survive as well as pups from unexposed mothers. Chlorpyrifos also affects the male reproductive system; exposure to a chlorpyrifos product has caused death of cells in male rat testes and a decrease in sperm production in cattle. Chlorpyrifos has caused genetic damage in human blood and lymph cells, mice spleen cells, and hamster bone marrow cells. Immune system abnormalities have been reported from patients exposed to chlorpyrifos. Many individuals report developing sensitivities to a broad array of substances following chlorpyrifos exposure. The second part of this factsheet will discuss human exposure to chlorpyrifos and the ecological effects of chlorpyrifos.
