Comprehensive management of cotton pests and diseases

Comprehensive management of cotton pests and diseases

1. Seedling disease comprehensive control seedbed should be selected in the sheltered sunny place, you can directly use the carbendazim seedbed spray sterilization, in order to facilitate the growth of cotton seedlings to reduce the occurrence of browning wilt and delay the spread of the wilt.
Cotton seed is one of the main bacterium sources of seedling disease. Therefore, killing the seeds is an important measure to control cotton seedling diseases. Can be sown before drying 2-3 days, or use seed coating agent for finishing the cotton seed, or use carbendazim seed dressing, or methyl forsterite soaking for 5 to 6 hours.
After Qi Miao, the earliest occurred was blight and anthracnose, combined with seedlings watered with carbendazim, or multiple manganese zinc, or methyl tocopherol pouring. Leaf disease uses carbendazim and chlorhexidine phosphorus sneeze. Control 2 to 3 times throughout the nursery period.
2. Integrated prevention and treatment of diseases and insect pests in the early stage of cotton reproduction will reduce the incidence of yellowing and wilt disease. In diseased fields where disease-infected varieties are still planted, comprehensive prevention and control measures must be taken to reduce the degree of damage. One is to dig deep for digging and prevent stains; the other is to apply pesticides for transplanting on the basis of seedling-free seedlings. The rooting water and nutrient solution were used to irrigate the roots with carbendazim and carbamide on the same day or the next day after transplanting. The third method was to sterilize the diseased cotton plants with ammonium bicarbonate. The pest control agents for cotton aphid, red spider, cockroach, red bollworm, cotton bollworm, etc., have been recommended above and are not repeated here.
3. Comprehensive control of pests and diseases in flower and boll stage.
After the arrival of cotton in August, its self-compensation ability was significantly reduced, and the types of diseases and insect pests were also significantly different from those in the previous period. The ability of natural enemies in cotton fields to control pests was weakened. At this time, the main pests in the cotton fields, the red bollworms and bollworms directly harm the harvested part of the cotton. If there is a slight mistake in prevention and control, serious cotton production reduction can be caused. In a few years after falling into the rainy season, blind locusts can cause cotton crop failure if they do not apply pesticides in the field. Therefore, the prevention and control of cotton pests and diseases in this period must be based on chemical control. The prevention and treatment of cotton bollworm and Spodoptera litura should be given priority to, as well as other pests. For the boll disease, agricultural control should be the main method, supplemented by pharmaceuticals. The insect control agents such as red spider, Spodoptera litura, and blind mites have been recommended above and are not repeated here.

ETR PSA Oxygen Generator


With PSA principles, ETR medical PSA oxygen generator can produce 93%±3% purity oxygen gas directly from compressed air. Compared with traditional Bulk liquid oxygen and cylinders oxygen, ETR on-site PSA oxygen generator can reduce cost down to 50 percentages. They can produce oxygen by your will, overcoming the limits of distance, location and transportation.

Compressed air is purified through the air dryer and filters to a certain level for main generator to work with. Air buffer is incorporated for smooth supply of compressed air thus to reduce fluctuation of compressed air source. The generator produces oxygen with PSA (pressure swing adsorption) technology, which is a time proven oxygen generation method. Oxygen of desired purity at 93%±3% is delivered to oxygen buffer tank for smooth supply of product gas. Oxygen in buffer tank is maintained at 4bar pressure.
