Embodiment 1

[0013] The row spacing of pear trees is 4m×8m, and the tree grows robustly. Sow 2.0kg of white clover per mu of pear orchard, which can be sowed by drill. The sowing period is April 20. 180ml of 0.3% SAVONA is diluted 1200 times and sprayed with 50% of conventional pesticides. The spraying period was in the peak period of the overwintering adult worms, the first to fourth generation nymphs, and the adult worms 2 days before the peak period. Sampling survey results showed that the population numbers of nymphs and adults of each generation and the leaf damage rate in the white clover intercropping + biopharmaceutical area were significantly lower than those in the clearing and bare land conventional application areas.

Embodiment 2

[0015] The row spacing of pear trees is 4m×8m, and the tree grows robustly. Sow 2.6kg of white clover per mu of pear orchard, which can be planted by drill. The sowing period is April 30. 240ml 0.3% SAVONA is diluted 1200 times and sprayed with 50% of conventional pesticides. The spraying period was in the peak period of the overwintering adult worms, the first to fourth generation nymphs, and 3 days before the peak period of adult worms. Sampling survey results showed that the population numbers of nymphs and adults of each generation and the leaf damage rate in the white clover intercropping + biopharmaceutical area were significantly lower than those in the clearing and bare land conventional application areas.

Embodiment 3

[0017] The row spacing of pear trees is 4m×8m, and the tree grows robustly. Sow 2.3kg of white clover per mu of pear orchard, which can be sowed by drill. The sowing period is April 25. 210ml 0.3% SAVONA is diluted 1200 times and sprayed with 50% of conventional pesticides. The spraying period was in the peak period of the overwintering adult worms, the first to fourth generation nymphs, and the adult worms 2 days before the peak period. Sampling investigation results showed that the population numbers of nymphs and adults of each generation and the leaf damage rate in the white clover intercropping + biomedicine area were significantly lower than those in the clearing and bare land conventional application areas.

Abstract

The invention relates to a method for ecologically controlling damage caused by psylla. According to the method, the row spacing of pear trees is 4m*8m, 2.0-2.6kg of intercropping crops are seeded permu in a pear garden, the seeding period is from April 20 to April <30>, and 180-240 ml of 0.3% SAVONA is diluted by 1200 times to be mixed with a 50% conventional pesticide application insecticide for spraying. The method for ecologically controlling the damage caused by psylla has the advantages that perennial plants such as white clovers or platycodon grandiflorum are intercropped, so thatthe plant diversity is improved, natural enemies are protected and assisted in migration, spraying of the biological agent SAVONA rich in potassium salt is combined to remove secreta of nymphs, and the synergistic effect of the SAVONA and the insecticide is used for achieving the sustainable control of the damage caused by psylla. The method for ecologically controlling the damage caused by psyllahas the advantages that the application amount of chemical pesticides is greatly reduced, the pollution of the chemical pesticides to the environment is reduced, pesticide residues of pear fruits arereduced, planted intercropping crops can be recycled many years, the method is environmentally friendly, the operation process is simple, the control effect is good, and the application prospect is broad.

Description

Technical field [0001] The invention relates to a method for ecologically controlling the damage of Psylla sylvestris, and its technical field belongs to the subject of plant protection. Background technique [0002] Psylla chinensis (Psylla chinensis) was originally an important pest of pear trees in Northeast and North my country. It is now spread all over the country and the damage is rampant. The damage rate of some pear orchards is almost 100%, causing tree weakness, early leaf fall, and affecting flower bud differentiation. A great threat to yield and quality. Since the 1980s, a large number of broad-spectrum insecticides such as pyrethroids have been used in pear orchards. Although it has effectively controlled the damage of Grapholitha molesta, it has also killed the natural enemies of Chinese pear psyllium, flower bugs and grasses. Lacewings, ladybugs, spiders, parasitic wasps, etc., have caused the Chinese Psylla chinensis to lose effective control of its natural enemie...
