| ABSTRACT: For a crop protection product to achieve its goal, the product must be applied and remain on the leaves until it is absorbed. This situation may be compromised due to rainfall after spraying, thus necessitating reapplication which increase the overall cost. Application technology research has focused on alternatives and solutions to mitigate this effect through the use of adjuvants. The objective of this research was to evaluate the deposit of spraying liquid on citrus seedlings using the products spirodiclofen, propargite, imidacloprid, lambda cyhalothrin, copper oxychloride, and copper hydroxide with water mixed with the adjuvants polydimethylsiloxane and phosphatidylcholine. Seedlings were subjected to simulated rains of 10mm at intervals of... |

| The effects of seven herbicides, four insecticides and one molluscicide were tested at concentrations of up to 10 mg/l on larvae of oysters, Crassostrea gigas (9 days exposure), and on laboratory cultures of the algae Isochrysis galbana and Chaeloceros calcilrans (21 days exposure). Ali of the pesticides tested had significant toxic effects on at least one of the test organisms. The strongest effects were those of lindane and isoproturon on survival and growth of C.gigas larvae, and of isoproturon and carbetamide on growth of Isochrysis and Chaeloceros cultures. The log-probit model for the relationship between dosage and effect, and Haber's rule for the relationship between duration of exposure and effect, hardly ever applied to our data. In sorne cases... |
