What are the citrus diseases and insect pests? How to prevent and cure? Netizens are also asked to help introduce citrus diseases and insect pests, such as anthrax, resin disease, scab, flower bud maggots, red spiders, aphids, scale lice, etc., and the land net collates the control methods of citrus diseases and insect pests, which are listed below for netizens' reference. Citrus disease control methods: citrus resin disease, anthracnose, scab, mildew smoke control methods: 77% can kill 2000-type 800 times solution, or 50% multi-mildew wettable powder 800-1000 times solution, or 60% nitrilazole-manganese-zinc wettable powder 1500-2000 times solution, or spray control with 80% Dasheng wettable powder 400% 600 times liquid and so on. Citrus pest control methods 1. Flower bud maggots: spray 1000 times of 80% dichlorvos EC + 90% crystal trichlorfon when the buds are white, and control aphids at the same time. 2. Mites (red, yellow and white spiders): spray with 40% Cryptophagus EC 1500 ~ 2000 times, and 34% sweep acaroid EC 1000 ~ 1500 times. The above three kinds of acaricides are used alternately or mixed. 3. Scale insects: in the initial stage of hatching, that is, late April and mid-May, 40% of the scale EC 1500-2000 times liquid spray can control sagittal scale, red wax scale, black spot scale, blow cotton scale and so on. 4. Aphids and whiteflies: spray with acetamiprid or imidacloprid 1000-2000 times. 5. Leaf miner: deltamethrin and Kung Fu EC can be sprayed evenly when the new shoot leaves grow to 1-1.5 cm. Phoenix butterflies can be used to artificially kill buds, eggs on tender leaves or silkworm-like larvae. Yellow plate can also be used to trap adults or control trichlorfon and trichlorfon. In general, fungicides and pesticides can be mixed (alkaline pesticides are used alone), which can not only improve the efficacy but also reduce the labor intensity.
