Many cotton farmers still believe that insect-resistant cotton does not control any pests, but it is not. This is because the currently-promoted insect-resistant cotton is resistant to lepidopteran pests such as bollworms and pink bollworms, but it is not resistant to underground pests, red spiders, cotton aphids, and blind locusts, and is resistant to beet armyworms. Sex is not ideal. Therefore, we must remind farmers in general that even if planted with insect-resistant cotton, it cannot be taken lightly for pest control.
The following methods can be used to control underground pests, cotton aphid, red spider and other pests:
First, when cottonseed meal occurs seriously, 40% omethoate can be used for 1000-1500 times, or 50% phoxim 1500 times, or 50% for 2000 times.
Second, the use of 73% Kezi special 2500 times and other drugs to control red spider, the effect is good.
Practice has shown that planting insect-resistant cotton does not require prevention and control of the first and second generations of cotton bollworms, and when there are 120 bollworms per 100 strains, they should be prevented and treated in time.
