Application of several herbicides and a combination of herbicides in two vineyards resulted in a perfect control of Bermuda grass by glyphosate and mixed or alternate applications of MSMA and dalapon. Johnson grass was eliminated by MSM A with and without the addition of dalapon. Dalapon combined with MSMA reduced the yield of the grapevines and their growth, as measured by the weight of pruning. Yields were also significantly reduced by aminotriazole and in one vineyard also by simazine. Reduced vegetative growth was caused by MSMA and glyphosphate.MSMA and glyphosphate reduced the chlorophyll content of the grape leaves and the reducing sugar content of the canes in winter. Amino triazole reduced the reducing sugar content of both leaves and canes and the nitrogen content of the canes. In one vineyard simazine reduced the chlorophyll content of the leaves and increased the nitrogen content of the canes. MSMA alone and in combination with dalapon increased the arsenic content of leaves, canes and fruits of grapevines. Arsenic levels were the highest in the canes, but still did not exceed 0-6 ppm. Levels were lowest in fruits and did not exceed 0-1 ppm. Dalapon reduced the chlorophyll content of leaves in June and increased it in July. It also affected the reducing sugar content of leaves and canes without affecting yields or growth. Efficacite de quelques herhicUles en vtgnoble et leur toxicite pour la vigneResume L' application de plusieurs herbicides et d'une association d'herbicides dans deux vignobles a permis une elimination complete du chiendent (Cynodon dactylon (L.) Pers.) avec des traitements au glyphosate et des applications simultanees ou alternees de MSMA et de dalapon. Le sorgho d'Alep (Sorgum halepense (L.) Brot.) a ete elimine par le MSMA avec ou sans addition de dalapon. Le dalapon associe au MSMA a reduit le rendement et la croissance de la vigne, comme l'a montre la

Among 18Bacillus thuringiensis isolates with spherical parasporal inclusion from soils, B. thuringiensis subsp. israelensis CAB199 was selected. It was showing over 90% mortality against Aedes aegypti and Culex pipiens moletus. It was confirmed that this B. thuringiensis subsp. israelensis CAB199 isolate also had a insecticidal activity against Culex inatomii that was occurred in the marsh. Because most of mosquito larva were primarily situated or shifted from under-to surface water, we need to select long floating formulations on surface water for controlling mosquito larva. It was tested the pesticidal and control effects in the laboratory and wetland with two formulation types of B. thuringiensis subsp. israelensis, for example, wettable power (WP) and suspension concentrate type (SC). Laboratory test showed that SC formulation type was relatively faster and more effective against 3 tested mosquito species, C. pipiens, Aedes aegypti, and C. inatomii. Otherwise, the control efficacy of SC formulation type was more rapidly appeared against C. inatomii in the wetland.
