Introduce two green and pollution-free kiwi pest control technologies, mainly physical control and biological control. Physical control Install insecticidal lamps in orchards every year from March to November. Frequency-vibration insecticidal lamps or solar-powered insecticidal lamps are hung. One lamp is hung on a flat dam of 50-60 acres and one lamp is hung on a mountainous area of ​​20-30 acres. The focus is on trapping scarabs, peach borers, Adult insects such as leaf rollers and penetrating moths. Insect prevention of yellow boards takes advantage of the color-tightness of pests and hangs yellow boards in the field to trap and kill small insects such as aphids, leafhoppers, and mosquitoes. In the early stage of the pest occurrence, use when the amount of pests is small, place 20-30 tablets per mu, and use 2 to 3 times. Tie insect traps take advantage of the overwintering habit of pests crawling down the tree trunks. Tie insect traps 50 cm above the ground from the trunk to trap mites, scale insects, leaf roller moths, etc., and destroy them after overwintering. Biological control 1. Avoid using broad-spectrum insecticides during the period when natural enemies are in full bloom. 2. Promote the planting of vetch, clover, alfalfa, etc. in the orchard to control the growth of malignant weeds in the garden, achieve the purpose of controlling weeds with grass, and reduce the use of herbicides; at the same time, create a good breeding and growth environment for natural enemies to achieve insect The purpose of pest control is to reduce the use of pesticides. 3. Use Bacillus thuringiensis to control pests such as scarabs and apple blue beetle; use mineral oil to control scale insects; use too resistant biological pesticides to induce plant resistance, and control anthracnose, brown spot, powdery mildew and other diseases.
