The main reasons for late control are: When there is too much precipitation or excessive fertilizer and water, the cotton plants are tall, the fields are closed, the ventilation and light transmission are poor, and the middle and lower parts of the bells fall off, resulting in a decrease in yield and quality. Causes: Farmers have a poor grasp of fertilizer and water management and chemical control technology, and most of them are controlled after the cotton grows and even grows. Countermeasures: First, for early-warning cotton fields, do not wait until they are prosperous. The second is after the top-dressing watering and rainfall, timely control according to fertilizer and water conditions. Third, the control should start from the seedling stage, to maintain a steady growth of cotton plants, the amount of commonly used to enhance the strength of the seedlings Mu 1 to 2 ml, Sheng Lei to the early flowering period of 6 to 12 ml, full flowering period of 12 to 15 ml. The fourth is to control the concentration rather low and not high, after the chemical control is still prosperous, it can be controlled again after 7 to 8 days, and the entire process is controlled 3 to 4 times. The fifth is watering in case of drought after chemical control.
