Abstract

The invention discloses a ginger bacterial wilt prevention and control method. The method includes the following steps that a disease-free field is selected for seed reservation or disease-free ginger blocks are selected to be planted; the field where ginger is planted is not subjected to continuous cropping, and can be in crop rotation with rice, one round can be carried out every other two years after the ginger is planted in dry land, continuous cropping needs to be avoided, plots with high terrain and good drainage are selected, quick lime is applied for disinfection after the plots are deeply ploughed, and phosphorus and potassium fertilizer is additionally applied; 500 ppm of agricultural streptomycin is used for soaking seeds for 48 hours or 800-fold liquid of 30% copper oxychloride is used for soaking the seeds for 6 hours, ginger seed notches are dipped in plant ash, and then the seeds are sown; diseased plants are pulled out, pesticide is applied for prevention and control, 0.5-1 kg of 3,000-4,000-fold liquid of 72% agricultural streptomycin soluble powder is applied to each hole or a 800-fold suspending agent of 30% copper oxychloride is used for leaching, application is carried out once every other 10 days, prevention and control are continuously carried out 2-3 times, and diseased ginger plants need to be burnt in a centralized mode without being thrown out on field edges. According to the prevention and control method, ginger bacterial wilt is reduced, the yield per unit area of fresh ginger is increased, the yield of the fresh ginger is increased accordingly, and market supply of the fresh ginger is increased.

Description

technical field [0001] The invention relates to a method for preventing and treating plant diseases, in particular to a method for preventing and controlling ginger blast. Background technique [0002] Ginger blast, also known as rot or soft rot, occurs widely in ginger-growing areas in Guangxi, generally losing 20%-30% of output, and seriously reaching more than 50%. Ginger plague mainly infects the roots of underground stems. The fleshy stems at the damaged part are yellowish-brown and water-stained at the beginning, lose their luster, and then gradually soften and rot. When the diseased part is squeezed, dirty white rice-like juice will flow out, giving off a foul smell. The damaged leaves are withered, bright yellow to yellowish brown, with curled edges, and finally the whole plant droops and dies. The symptoms of this disease are similar to those of root rot caused by fungi. When diagnosing, you can use a microscope to examine the section or use the fire slide method t...
