The “Coffee Rejuvenation Strategies in Vietnam” has risked not being complete on schedule, with the low survival rate of seedlings on replanted soil, due to the nutrient loss and imbalance supplements after a long-term of monoculture and intensive cultivation. In this study, measures, including biochemical and organic treatments were applied to replanted coffee farm, in order to supplement the loss of nutrient cycling. Survival rate, growth indicators, and soil properties from the controls and treatments, were monitored and compared during the experimental periods. The results suggested the optimal tillage model as follow: Remove old coffee trees with their stumps and roots; liming 1.5 tons/ha; dry tillage soil for the first 6 months; Intercrop Mexican marigold (Tagetes erecta) with new coffee plants for the next 6 months; From the second year, apply 5 kg of microbial organic fertilizer /hole/year; bury 30 kg of green manure/hole/2–3 years; apply NPK fertilizers according to the governmental recommended procedure. -

STORED-PRODUCTENTOMOLOGY Insecticidal Activity of Floral, Foliar, and Root Extracts of .Tagetes minuta (Asterales: Asteraceae) Against Adult Mexican Bean Weevils (Coleoptera: Bruchidae) DAVID K. WEAVER,l CARL D. WELLS,2.3FLORENCE V. DUNKEL, WOLFGANG BERTSCH,2 SHARLENE E. SING,l AND SHOBHA SRIHARAN4 Department of Entomology, Montana State University, Bozeman, MT 59717 J. Econ. Entomol. 87(6): 1718-1725 (1994) ABSTRACT Experiments were conducted to determine speed of action and toxicities of extracts of Tagetes minuta L., a source of naturally occurring insecticidal compounds. LC50 values for male and female Mexican bean weevils, Zabrotes subfasciatus (Boheman), were determined for /loral, foliar, and root extracts of T. minuta. The 24-h LCso values ranged from 138 lJ-g/cm2 for males exposed to the root extract (most susceptible) to 803 wlJcm2 for females exposed to the foliar extract (least susceptible). Increasing the duration of exposure 2 to 48 h decreased all LCso values 20-30 lJ-g/cm • Males were more susceptible than females. The time to incapacitation for 50% of the test insects (IT 50) for floral and foliar extracts indicated fast-acting, volatile components, whereas the root extract data indicated slower-acting components, likely a result of the interaction of photophase with time- dependent efficacy. Floral and foliar extracts of T. minuta may be useful as insecticides for controlling stored-product pests. KEY WORDS Zabrotes subfasciatus, Tagetes minuta, extracts MARIGOLDS,Tagetes spp., are a useful intercrop extract was 8.1 mg/g for Rhyzopertha dominica in agriculture. -

Henderson, L. (2007). Invasive, Naturalized and Casual Alien Plants in Southern Africa
Bothalia 37,2: 215–248 (2007) Invasive, naturalized and casual alien plants in southern Africa: a sum- mary based on the Southern African Plant Invaders Atlas (SAPIA) L. HENDERSON* Keywords: biomes, casual alien plants, invasive plants, Lesotho, naturalized plants, roadside surveys, SAPIA mapping project, South Africa, Swaziland ABSTRACT The primary objective of this publication is to provide an overview of the species identity, invasion status, geographical extent, and abundance of alien plants in South Africa, Swaziland and Lesotho, based on fi eld records from 1979 to the end of 2000. The dataset is all the species records for the study area in the Southern African Plant Invaders Atlas (SAPIA) database during this time period. A total of 548 naturalized and casual alien plant species were catalogued and invasion was recorded almost throughout the study area. Most invasion, in terms of both species numbers and total species abundance, was recorded along the southern, southwestern and eastern coastal belts and in the adjacent interior. This area includes the whole of the Fynbos and Forest Biomes, and the moister eastern parts of the Grassland and Savanna Biomes. This study reinforces previous studies that the Fynbos Biome is the most extensively invaded vegetation type in South Africa but it also shows that parts of Savanna and Grassland are as heavily invaded as parts of the Fynbos. The Fabaceae is prominent in all biomes and Acacia with 17 listed species, accounts for a very large proportion of all invasion. Acacia mearnsii was by far the most prominent invasive species in the study area, followed by A. -

Here the antibacterial activity of spent substrate of Pleurotus ostreatus combined with medicinal plants was evaluated. We designed six mixtures (barley straw, barley straw/Chenopodium ambrosioides L., barley straw/Mentha piperita L., barley straw/Rosmarinus officinalis L., barley straw/Litsea glaucescens Kunth and barley straw/Tagetes lucid Cav) to be used as a substrate of cultivation of mushroom. -

Abstract Introduction: Plants have been commonly used in popular medicine of most cultures for the treatment of disease. The in vitro antimicrobial activity of certain Argentine plants used in traditional medicine has been reported. The aim of this study was to investigate the antimicrobial, anti-biofi lm, and anti-cell adherence activities of native plants (Larrea divaricata, Tagetes minuta, Tessaria absinthioides, Lycium chilense, and Schinus fasciculatus) collected in northwestern Argentina. Methods: The activities of the fi ve plant species were evaluated in Bacillus strains and clinical strains of coagulase-negative Staphylococcus isolated from northwestern Argentina and identifi ed by 16S rDNA. Result: Lycium chilense and Schinus fasciculatus were the most effective antimicrobial plant extracts (15.62µg/ml and 62.50µg/ml for Staphylococcus sp. -
