In this study adsorption and desorption of three carbamate pesticides namely, oxamyl (I); S-Ethyl-N-(methyl carbamoyl) oxythioacetimidate (II); and N-Phenyl (ethyl carbamoyl) propy1carbamate (III) by Na+-, Ca2+¬montmorillonite, and humic acid-montomorillonite, was investigated. The adsorption of pesticides was in the order III I II; adsorption for Na-montmorillonite was more than that for Ca-s ...

Trends of dithiocarbamate residues in raspberries in the Republic of Serbia over the period 2007/2010
Pucarević, M., Educons University et al. 
Dithiocarbamates (DTC) are among the most commonly used pesticides in the world. In the Republic of Serbia almost 300 active substances are registered including five dithiocarbamate fungicides (ziram, mancozeb, metiram, propineb and tiram). In the raspberry protection from fungal diseases only mancozeb combined with metalaxyl-M (Ridomil Gold MZ 68-WG; mankozeb 640 g/kg + metalaxyl-M 40 g/kg) o ...

Effect of a carbamate insecticide, Carbosulfan on the foraging behaviour of Apis mellifera L. foragers
Thakur, Seema Singh et al. [jan-jun2007]
Investigations were done to observe the effect of a carbamate insecticide, carbosulfan on the foraging activity of Apis mellifera L. The experiment consisted of two sets. In the first set the bees were allowed to come in direct contact of insecticide treated surface while in the second set a wire net was kept over the treated surface so that only odour repelled the bees. Carbosulfan was found ...

A simple method for the methylation of selected pesticides with trimethylphenylammonium hydroxide is described. The reaction product was the N-methyl or methoxy derivative of the examined substance. Derivatization by on-column methylation has recently been developed for the analysis of selected phenylurea and uracil herbicides, carbamate insecticides, and benzimidazole fungicides. The same met ...

The objectives of the work described here were to develop a one-pack insecticide combination that was particularly suited to the rice pest complex while presenting minimal hazard to man and the environment. The mixture contains a low concentration of a new pyrethroid, alphacypermethrin (FASTAC) and a low to moderate dose rate of the carbamate, BPMC. Detailed field trials have been carried out ...

In controlling the causer of leaf spot, Pseudomonas tomato by the application of chemical preparations, greater efficiency was achieved by preventive than curative application. With preventive application all preparations on the basis of copper and their combinations could be used. From the group of dithiocarbamates, Cineb, Mankoceb and the combination Cineb+Mankoceb could be used. With curati ...
