How does the potato black shank symptom map prevent potato black shank disease?
Tao Liyuan teacher, Hao manager, Guan teacher and a group of three, arrived in Hulan District of Harbin yesterday, Sanjiatun, was invited to the potato farmers to see a doctor. The potato has grown 4-8 leaves, and many of the leaves of the plants have begun to snoring. It is not long! Through the observation of the lower ground, the roots are inspected. Teacher Tao has discovered a large number of black rickets! Here to remind farmers, black rickets It is a very serious disease of potatoes, because it is not easy to fight drugs, it can only be treated with roots, and sometimes it is even more difficult to treat than late blight. There are three reasons for black rickets: 1. Seed potato bacteria, potato block disinfection has serious misunderstandings. It is understood that many local farmers still use common carbendazim, agricultural streptomycin mixed with seed potatoes, these two fungicides have been very common, for many of today's germs Killing effect is very poor, it is not recommended to continue to use here; 2, the field sputum occurs seriously: Many plots, we found that black plague is obviously more, the underground pests cause damage to the roots of the potato, the wound is easily infected by the disease, therefore, it is recommended that farmers not only seed dressing or planting To prevent the use of drugs, we must focus on the treatment of underground pests; 3, sowing, after emergence, did not prevent the disease on time, when the potato emergence about 80%, we should prevent the occurrence of black rickets, black smut, underground pests and other pests and diseases, when the seedlings are small, the medicine is very It easily penetrates into the base of the stem and has the effect of bactericidal prevention. Once it is missed, the late onset will cause a reduction in production and it is not easy to treat. Coming back from the ground, I probably walked through 7-8 plots, more than 800 mu of land, and returned to the peasant's home. Teacher Tao wrote down the medication recommendations for the farmers. Prevention method: 1. Select the seed potato of the seed potato company with less disease occurrence in that year; 2, seed potatoes must be disinfected with chemicals: azoxystrobin + neutrophin + imidacloprid, seed dressing; 3. Timely prevention of large amounts of water after emergence. This article URL: How does the potato black sputum symptom map prevent potato black shank disease?
