How to control crop pests and diseases in spring
Make overall plans and take care of the first battle of pest control in wheat fields. According to recent surveys conducted by various localities, the current incidence rate of wheat sheath blight is 86.01%, and the diseased plant rate is 23.30%, which is obviously heavier than the same period of last year. Wheat spiders are heavier in the dry buckwheat and sorghum regions, and wheat aphids are also common. In addition, the winter wheat planthoppers, a vector of rice stripe disease and maize rough dwarf disease, have a large amount of wintering in wheat fields, which is 3-9 times that of the same period of last year. Early control of wheat fields can achieve a multiplier effect in controlling the development of cardinal number. According to the current characteristics of wheat diseases and insect pests, all localities should make overall plans and take good care of the overall battle against wheat sheath blight, wheat spiders, locusts and sloughs. The control time should be stable in the middle or late March and the pests and diseases should begin. When the hazard rises. In terms of prevention and control, it is necessary to emphasize the use of sufficient doses, increase the amount of water, and spray at the base of wheat in order to improve the control of wheat sheath blight. Prepare as early as possible and do a good job of seed treatment of spring crops. In rice, we must vigorously promote the first net soaking to prevent rice stripe disease, and promote the use of evil soaking in the prevention of rice bakanae, dry apices disease. The promotion of the use of sulphuric acid, sulphuric acid and Lingfu mixture, and imidacloprid in cotton, to prevent seedling diseases and aphids. The use of imidacloprid and phoxim seed dressing was promoted on corn to control corn rough dwarf disease and underground pests. The use of carbendazim for seed soaking in hawthorn and peanuts has been promoted, and hawthorn black spot and peanut dumping disease have been prevented. Strengthen the field management, and do a good job in comprehensive prevention and control of vegetable diseases in spring protected areas. Comprehensive prevention and control of vegetable diseases in protected areas in the spring should be implemented: to strengthen fertilizer and water management, apply sufficient green manure, and to promote green growth and rejuvenation; for undistributed fields, tar covering and sheds should be used to increase ground temperature, and the planted field should be fully utilized. Clear weather, increase the room temperature, increase the illumination time in the greenhouse, and pay attention to timely ventilation; timely spraying protection, in the early stages of disease, targeted and timely spraying precautions, spraying the best use of dust agents and aerosols to reduce humidity , improve control efficiency.
