【 摘 要 】

Comparison of Different Pesticide Treatments of Cotton Seed in Burundi and in Greece. The effects of several active ingredients and various cotton seed treatments have been compared in 7 trials realized in Burundi and Greece in 1993 and 1994. The trials led in Burundi show the very high significant efficacy of imidacloprid on Aphis gossypii Glover at 3 g a. i./kg associated with chlorothalonil at 08 g a. i./kg seeds, when applied by pelleting on delinted seeds. In Greece, the absence of parasitic pressure at the beginning of the growing season did not allow the classification of the applied treatments concerning their efficiency to control cotton pests. The ecophysiological observations realized during this experimentation show a significant improvement of the bail maturation precocity in plants issued from pelleted seeds with an average dose of 2.2 g imidacloprid and 2.4 g TMTD per kg of seeds. On average, plants issued from treated seeds matured 10 days earlier than the untreated one.
