Abstract

The invention belongs to the technical field of guava planting, in particular to a method for preventing and controlling guava pests. The method includes the following steps: (1) applying straw fermented substrates to soil according to 50-60 kg / mu, ploughing for 10-15 cm, and standing for 15-20 days; (2) mixing vermiculite and polyacrylamide dry powder according to a weight ratio of 1: (1.1-1.5),applying the mixture to the soil according to a weight ratio of 30-40 kg / mu, ploughing for 10-15 cm, standing for 3-7 days, and then fix-planting or planting; (3) pouring 200-300 g / tree of traditionalChinese medicine fermented fertilizers on guava roots 3 days after the guava is fix-planted or planted; and (4) spraying an insect prevention liquid on trunks of the guava trees the next month afterthe guava tree is fix-planted or planted, and spraying the insect prevention liquid on the trunks, leaves or fruits every 2-3 months thereafter. The method has a broad-spectrum insecticidal effect, can inhibit the growth and development of pests, is simple, does not need to use pesticides, has no toxicity to human bodies, and has high safety.

Description

technical field [0001] The invention belongs to the technical field of guava planting, in particular to a method for preventing and controlling guava pests. Background technique [0002] Guava is an evergreen shrub or small tree belonging to the family Myrtaceae. The fruit is rich in various nutrients needed by the human body. It can be eaten fresh or processed into beverages, jams, canned food, etc. It can be used as medicine and has become one of the important cultivated varieties of fruit trees in southern my country. However, the phenomenon of guava pests has caused losses to agricultural production and dealt a blow to farmers' confidence in planting. At present, guava pests mainly include aphids, nematodes, scale insects, fruit borers, fruit flies, mites, mealybugs, longhorns, scarabs, grubs, red spiders, thrips, poisonous moths, core borers, stinkbugs, inchworms, caterpillar. [0003] Scale insects can damage the leaves, branches and young fruits of guava, usually in ...
