Vegetable virus disease is the most common disease in agricultural production. There is no good method for the treatment of this disease. However, if the selection of pesticides is strengthened, it will not make the disease spread too seriously. Here are several preventive measures:
TORICH is a main producer and exporter of Seamless Steel Tubes and Pipes in China.
Seamless Steel Tubes and Pipes are produced with Round Mandrel and Die to produce Round Shapes of Seamless Steel Tubes,
Seamless Precision Steel Pipes
Seamless Alloy Steel Tubes & Pipes
Seamless Steel Tubes and Pipes Size range is:
Honing seamless steel pipes (Hydraulic Cylinder Steel Tube, pneumatic cylinder tube) produced by undergo cold forcing and annealing for a cured tensile strength reaching over 52kg/cm², before the pipes are milled by precision machinery, regulating the tolerance in inner diameter at an H8-H9 level, with surface roughness at between Ra 0.2μm, which helps to extend the life cycle of the cylinder, and reduces the wear and tear of the seal.

1. Create an environment that is not suitable for the survival of viral diseases, and reduce the temperature and humidity. Mainly in the summer and autumn when planting, take corresponding measures to cool down and humidify, such as covering the shade net with vegetables, watering a small number of times.
2. While using pesticides for prevention and control, some insect nets can also be used to kill pests such as whitefly and thrips.
3. Which pesticide to prevent. Recommended agents are: Ningnanmycin, pyrimidine, amantadine, dextran. It is best to select some water agents or pesticides that are highly systemic. It should be taken care of when formulating, for example: morpholinium hydrochloride + nymidine.
The combination of growth regulators such as chitin, sodium nitrophenolate, alizarin, etc., may enhance plant resistance after application, allowing plants to recover quickly from pathological conditions.
