The effects of treated pesticides on biological value of seed in some field crops

This study was conducted to determine the effect of different doses of pesticides, which are the most common use as seed chemicals, on the biological values of seed on five varieties of each of corn, wheat and sunflower species. The research were carried out accordance with the 3- factor randomized plots experimental design in Limagrain Group / Karacabey seed laboratories. It was determined that germination values were adversely affected in Aprin XL 350 ES 300 ml dose which was routinely applied in sunflower, whereas this was not the case in Cosmos 500 FS application. The optimum dosage was 300 ml for Aprin XL 350 ES and 600 ml for Cosmos 500 FS. It was determined that the dose ratio could have different effects on germination values in maize and the highest germination values were determined in 100 ml dose of Maxim in DK / 5 cultivar and in 500 ml dose of Gaucho in DK / 3 cultivars. It was determined that high doses of both chemicals adversely affected germination rate. Lamardor New FS 170 dose increase in wheat positively affected germination in almost all varieties and highest germination value was found in Pamukova with 30 ml dose for 10 days and Golia with 60 ml dose for 180 days.
