“The pepper disease in the protected area is dominated by root rot.†Bao Guofang, an agricultural technology extension worker at the Agricultural Comprehensive Service Station in Ande Town, Jixian County, said that the disease of planting pepper in the protected area mostly invaded from the root and neck, and the diseased part was dark brown and sag. Or shrinking, the lesions can surround the stem, causing root death and plant wilting. Specifically, the pathogens in the greenhouse are mainly spread by irrigation water, and the disease center is mostly formed in the low-lying water in the greenhouse, the soil is sticky or the membrane is leaking. The most important factor affecting the incidence is soil moisture. The higher the soil water content, the faster and heavier the disease, especially the flooding of large water, the root of the pepper is immersed in the water, and it is easy to cause damage.
The prevention and control of pepper plague in greenhouse can not be ignored in the process of seedling cultivation and planting. It is necessary to prevent the seedling bed from pre-prevention measures and prevent seedling disease.
Before seedling, use 50% carbendazim 10g per square meter and mix 20kg of good seedbed soil, apply 2/3 of the soil to the seedbed, and use 1/3 for the seedling.
In cultivation, growers should also pay attention to disease prevention and implement high ridge cultivation. Specifically, the height of the ridge is 90 cm wide, the top is 50 cm, and the bottom of the groove is 20 cm wide, and the double rows are planted on the upper sides of the high ridge.
Prevent excessive irrigation, prevent flooding of large water, and do not make the base of the plant contact with water, so as to keep the ground dry and see wet.
Pesticide prevention and attention attention to several time nodes: First, before planting, use 25% of metalaxyl WP 0.5 kg per acre, 70 kg of water to disinfect the soil; second, spray and irrigate with the solution after planting. In the early stage, the stems and the surface of the plants are sprayed before the onset to prevent the initial infection; in the middle and late growth stages, especially after the discovery of the central diseased plants in the field, the roots should be sprayed and irrigated in time to close the disease center, once a week, continuous control 2 3 times. The medicament can be used as a 50% creamer copper wettable powder 800 times solution or a 58% Raydormer wettable powder 500 times solution.
