First, the cotton sowing period. Farmers should focus on preventing and controlling disease and wilt disease. Farmers can use anti-(endurance) pest varieties such as Suimian 53, Kemian No. 6, Noza No. 5, Zhongmian No. 53, Zhongmian No. 48, and coated seeds.
Seedling transplanting cotton field selection of disease-free or custom soil seedlings nursery to ensure that the nutrition soil does not contain dry, yellow wilt and other pathogens; seedbed soil mixed with hymexazol, carbendazim, enemy cough, etc. for seed bed disinfection; use large Breeding seedlings to ensure that the cotton seedlings grow robustly in the seedbed.
Farmers need to rotate reasonably to reduce the accumulation of pathogens in the soil and reduce the incidence. At the same time, it is necessary to remove the weeds and roadside weeds in the cotton fields to reduce the number of blind maggots and the number of larvae of the cotton leafhoppers.
Second, the cotton seedling period. Farmers should focus on the prevention and control of Miao disease, blind borealis, cotton leafhoppers, cotton thrips, seedling mites, and ground tigers. Farmers should timely cultivating and weeding and topdressing to shorten the period of seedlings. In the case of heavy rainy weather, the vaccine is controlled by spraying with carbendazim, thiophanate-methyl, and the like.
When the number of larvae was 100, the use of fipronil, malathion, acephate, chlorpyrifos, dichlorvos, profenofos and other agents was controlled by dilute spray; the rate of aphids in cotton leafhoppers was low. At the time of 15% treatment, over 15% of the general rule, the drug can be used Ling Ling, acetylene, Avermectin and its compound; the cotton planted horse before the transplanted strain rate of 5%, move When the planted rate of infected plants reached 20%, imidacloprid and acetamiprid were used for prevention and control; control of earthworms used deltamethrin, fenvalerate and other pyrethroid pesticides. The number of 100 seedlings in the seedlings of cotton seedlings before the three-leaf stage of cotton reached more than 1,000, and when more than 2,000 were obtained after the three-leaf stage, control was performed using imidacloprid. When there is a lot of rain, the low-lying plots pay attention to the control of snails, polyacetal, carbaryl, and tetra-ethylaldehyde are used.
Third, the cotton bud period. The cotton farmers should focus on the prevention and control of blind borers, wilt disease, and second-generation cotton bollworms. Farmers should timely pruning, cultivating and weeding, pay attention to clearing the ditch, control and prosper. After the harvest of wheat and oilseed rape, the larvae were exterminated and the natural enemies were fully transferred to the cotton plants in order to control the damage. For cotton fields that have symptoms of potassium deficiency, potassium fertilizers such as potassium chloride are topdressed in time, while potassium dihydrogen phosphate is sprayed on the leaves for potassium supplementation.
The amount of nitrogen fertilizer is too large, cotton fields with early occurrence of cotton fields, cotton fields with many weeds and cotton fields with tracts of trees nearby are required to focus on the prevention and control of blind stink bugs. The pesticides should be applied before 9 o'clock in the morning and after 5 o'clock in the afternoon. . Non-Bt cotton and early-onset cotton fields, when 100 young second-generation larvae of cotton bollworm are 15-20, nuclear polyhedrosis virus is used to prevent and control, such as high amount of residues, quick-acting agents such as phoxim and Dovey and other prevention and treatment. When fusarium wilt was first seen in the field, it was irrigated or sprayed with fulvic acid, oligoaminoglycans, and bactericide.
Fourth, cotton flowering period. In the early period (mid-July to early August), cotton farmers should focus on prevention and control of three generations of cotton bollworms, Spodoptera litura, cotton leafhoppers, and cotton thrips. In the later period (after mid-August), the focus should be on the prevention and control of blind and four- and five-generation cotton bolls. Insects, cotton leafhoppers, Spodoptera litura, cotton thrips, cotton aphid, and bell disease.
Farmers should promptly raise their hearts, remove side-effects, and wipe off buds; after topping, chemical adjustments should be conducted according to the growth of cotton and timely removal of Spodoptera litura egg masses. If there is a lot of rain, pick the bells and spread them in time.
When the youngest larvae of 100 third-generation cotton bollworms were 10-15, and 100 young larvae of the fourth- and fifth-generation larvae were young, they were applied at the peak stage of young larvae. Three generations of selected pyrethroids or hexaflumuron and its compounding agents, and four or five generations of organic phosphorus, carbamates, pyrethroids, single agents or mixed formulations are used interchangeably. When one hundred nestling larvae of Spodoptera litura were hatched, pesticides such as hexaflumuron, tebufenozide, chlorpyrifos, and phoxim were used before the second instar larvae dispersed. Pesticides with different mechanisms of action should be alternately used, and attention should be paid to the prevention and control of Spodoptera litura in crop fields such as soybeans and hawthorn outside the cotton fields. When the blind stink bug is heavy, the farmer can rotate and use the medicine to control. When the weight of cotton thrips and horses was heavy, they were treated with imidacloprid and acetamiprid.
