Prevention of root rot requires the combination of pesticide agriculture
Root rot is a relatively common disease. It is not feasible to treat root rot disease. It is impossible to rely on pesticides. Galv Mounting Bracket Cw Support Hook DWG

1. Agricultural control methods:
1 It is clear from the above causes that when the ditch is cut on both sides of the soil with high soil, it should not be too close to avoid injury to the root system.
2 It is also necessary to choose a relatively flat soil for planting due to a large amount of water and improper drainage.
3 If the soil in the planting area is not flat, it does not matter, but do the drainage work and drain the water, especially during the rainy season.
4 soil viscosity is too high, easy to cause soil agglomeration, easy to cause roots underdeveloped. Wearing clothes that are too tight with humans makes the body uncomfortable.
5 Everyone knows that the use of any fertilizer that is not decomposed is likely to cause the incidence of disease. This is also the reason for the blight disease introduced earlier. Applying organic fertilizer, potassium fertilizer and phosphate fertilizer to make the plant "strong" to enhance disease resistance.
6 seed bed selection, the crops to be seeded are best to choose the seedbed of different crops last year, that is, to plant the crops.
7 selection of quality seeds is also a good choice. High quality seeds can also largely resist the occurrence of diseases.
Pesticide control is closely related to fungicides:
Like other diseases, pesticides control root rot first is seed disinfection, then soil disinfection, and finally crop selection for crops after onset.
1 seed disinfection before planting. It is also the most common first step to reduce the disease.
The amount of seed disinfection: Because the seed is compared with the soil, the area is small. Therefore, seed dressing can use a relatively low drug. 600-800 times solution of carbendazim or 800-1000 times solution of carbaryl carbendazim 2 before planting soil disinfection. The second step is to reduce the disease.
Soil disinfection is relatively higher than the use of seed disinfectants. 1200-1500 times solution of carbendazim or 1500-2000 times solution of carbaryl
3 roots after onset. The third step is to reduce the disease.
The root irrigation is similar to the soil disinfection, and the application area is large, so the dosage is the same. 1200-1500 times the solution of the carbaryl or 1500-2000 times the solution of the carbaryl .
