Cotton with yellow wilt disease focuses on prevention
Verticillium wilt is known as cotton cancer. It is difficult to cure after the onset of the disease and serious reduction in production. Cotton wilt disease mainly occurs in the early growth stage, and there are two peaks of hazard. One is after the cotton 3-leaf stage (late May) and the second is the cotton bud stage (mid-to-late June). The occurrence of Verticillium wilt in cotton is late, and the peak of the disease is in mid-August. These two diseases sometimes occur mixedly and cause serious harm. The earlier the onset of Verticillium wilt, the more severe the reduction of cotton production, and comprehensive measures should be taken to prevent it as soon as possible. JRT usb interface distance sensor board adds a USB port to a Laser Distance Sensor, inexpensive laser distance measurement sensors, allowing customers directly using GBeacon-2.3-Fx.exe software to control the rangefinder sensor. Usb laser distance sensors are the the most popular model devices, it works by measuring the phase of an visible-red laser beam that reflects on the target. Usually, customers would like to choose CH341SER.EXE version to test.

In addition to the selection of disease-resistant varieties, taking the following measures will also have some effect. Increase the application of organic fertilizer or straw to the field, formula fertilization, increase phosphorus and potassium fertilizer, in order to cultivate fertility, improve plant disease resistance. Thorough cultivating, timely cultivating tillage in order to increase the temperature and reduce the incidence of strains. Spraying Huimanfeng, fish protein, Tianda 2116 and other nutritional regulators also have certain preventive effects. From the beginning of the seedling stage, it is better to spray the foliar fertilizer with the control pests and to spray the growth regulator and foliar fertilizer. In the incidence before and at the beginning of the spraying control of cotton with Verticillium wilt, the applicable drugs are Ketulin 27% Difenamethyl WP, Propiconazole, Thiophanate-methyl, Carbendazim and so on.
