1. The cockroach method is a tiger that is harmful to cotton seedlings. It is customary to produce eggs in field clods (about 70%) and dry grass sticks (about 20%). According to this rule, in the period of spawning to the hatching period, timely cultivating cultivating, or mobilizing the masses to dig on the field, can often reduce the hatching rate of eggs. According to the survey, the cotton field was only 3%, and the cotton seedlings were only 3%, and the number of cotton seedlings was as high as 11%. Linyi Fertilizer Network Copyright

3. After the larvae of the grass trapping method exceeds the third age, the drug resistance is enhanced, and the ground spraying is often difficult to receive the expected effect. The grass can be trapped by the grass, that is, the fresh grass is evenly piled in the field in the evening, 100 piles per acre. The area of ​​each pile is about 0.1 square meters. The next morning, the grass is piled up to catch insects, so that for 5 to 10 days in a row, most of the larvae can be killed. The haystacks are usually replaced every 3 to 4 days; after drying in the sun, some water can be poured to improve the trapping effect. Linyi Fertilizer Network Copyright
