Abstract
Toxicity Effect of Some Recommended Bollworms Insecticides And Their Mixtures With Fungicide Against The Cotton Bollworms, Boll Rot And Yield Production In Egypt Cotton Filed.
Highlights
The cotton is one of the oldest plant fibers cultivated in the world, and it has been used for producing natural raw materials for the textile industry, and by the use of its products for other important purposes, such as edible oil, pharmaceutical and animal feed oil (Chitarra, 2008)
The obtained results showed that the field application of two recommended insecticides against the cotton bollworms gave a high significant efficacy when dividedly mixed with thiabendazole as fungicide (Tecto® 50% SC)
In the last decade due to the change in the conventional agricultural practices in cotton growing in Egypt, especially in the coastal area and the West Delta region, where the cultivation of cotton is late than its original date we have noticed as researchers in the science of cotton increase the incidence of boll rot
