Abstract
A field experiment was carried out in Aydin region, Turkey during the two successive cotton growing seasons 2010 and 2011. The compounds have did not affect the population amount of Empoasca spp., Bemisia tabaci Genn., Frankliniella spp., whereas they affected Aphis gossypii Glov. and Liriomyza trifolii Burgess infestation. The highest population of Aphis gossypii was observed in Active Black Up treatment. On the other hand, the highest damage caused by L. trifolii was in Promina treatment. Among the predators, population in Thysanoptera order was significantly different in the treatments. More thrips populations were observed in Promina. The application of compounds significantly affected on the yield. The highest yield was obtained from Aminoquick treatmetn that has 95% organic matter and produced 28% more yield compared to the control. Treatments had no significant effects on plant height, lint percentage, boll weight, fiber properties, except for number of boll per plant and micronaire. The results showed that these compounds increased the yield, did not enhance the pests' population and not harmful to predators except for Thysanoptera. Thus, containing seaweeds and more organic foliar fertilizer compounds should be considered in integrated management of organic or conservative cotton fields.
