Prevent Cotton Blindness
Leptospirosis occurs in more than one generation in a year (5th generation in the north), adult longevity (40-50 days for females), large number of eggs laid (250-300 eggs per female for the first generation), and often forms a generation overlapping. In addition, the adult fly is strong, the initial damage of the cotton plant is not easy to detect, and sometimes the medicine is disturbed by the weather, so it is more difficult to control. If you have a greater grasp, you need to have a keen observation ability and rich experience. Among them, it is one of the key measures to do a good job of monitoring and controlling the first and second generations, and to reduce the number of insects in the previous period. Therefore, the cure for cotton blind lice is mainly on the legs, on the eyes, on the brain, rather than the main back sprayer. There are many hosts in the population of Lami, and according to information and observations by the author in the past decade or so, with the exception of cotton, jujube trees and alfalfa are the favorite in Hebei, and weeds (commonly known as grey vegetables) and artemisia are Favorite. After September each year, the wintering of the eggs in the cotton plants and the host remnants or roots can also occur in the soil and in the bark. During the winter, most of the northern part of the cotton region has very little snowfall, and the higher temperatures make it safer for the winter to pass through the winter. In addition, there are more rainfalls in the spring and weeds are born earlier. This provides favorable conditions for the early incubation, massive hatching, and active nymphs of the Lumbricus. . The author recently observed that, in the last year's grey side of the cotton field, almost all of the 1-3 larvae of the green-lipped nymph were active. After the emergence of adult larvae, they migrated to the cotton field in large numbers. The cotton seedlings near the edge of the ground, the edge of the house, the edge of the grass, and the edge of the tree are now harmed by the blind locust. The typical symptom is the emergence of dark spots and dark spots on the young leaves that have just emerged. If the growing point suffers damage, the formation of headless or multi-headed cotton in the future should cause high alertness to the cotton-growing households. At present, the source of the green-legged locust is largely hidden in the weeds on the ground, and the nymphs are afraid of being exposed. Therefore, it is more important to eradicate land and weeds in cotton fields in combination with pest control. If the infected cotton seedlings are found, it is not necessary to fight drugs all over the field. Instead, the investigation should be based on the observation and spraying. Nymphs damage cotton seed sooner or later and hide during the day. No dew day can fight drugs sooner or later, cloudy days can fight drugs throughout the day. With organic phosphorus pesticides can be controlled, do not have to buy expensive "high-precision new pesticides" or "to cure pesticides." In the new situation where cotton-planting is facing high costs and low returns, pest control should not spend a dollar more. 2022 New Laser Distance Sensor
