Willow willow fleautiauxia armata method for integrated control
Technical field
The present invention relates to a kind of willow willow fleautiauxia armata method for integrated control.
Background technology
The important pests of willow is that willow fleautiauxia armata belongs to coleoptera Chrysomelidae willow fleautiauxia armata, and this one-tenth, larval feeding willow blade become to incise or hole, and wherein 7-9 month Pests Damage is the heaviest, can, by nascent tender shoots and the tender leaf food light of willow, have a strong impact on willow normal growth.In 10 months, the last ten-days period lower tree successively, with adult place survive the winter.Mainly the method for preventing and treating is in this insect pest emergence period at present, adopts the anti-therapy of spraying insecticide, on average weekly, and the method can not obviously alleviate harm in the insect pest phase of containing, and with high costs, contaminated environment.
Summary of the invention
The object of the present invention is to provide easy, the effective willow willow fleautiauxia armata method for integrated control of a kind of method.
Technical solution of the present invention is:
A willow willow fleautiauxia armata method for integrated control, is characterized in that: step is as follows:
(1), in the last ten-days period in September, when seemingly-dead property appears in adult and larva, employing 20% is killed 1500 times of liquid of chrysanthemum ester tree body is sprayed;
(2) in the middle ten days in December, willow sylvan life soil is ploughed deeply to 25cm, by hiding insect in soil, come out and freeze to death;
(3) in Second Year late January, in willow sylvan life, sow 3% Isofenphos methyl granule, every mu of consumption, at 500-700 gram, can infiltrate soil and poison the insect of hiding into soil with poison, can make soil getting fat again, healthy and strong willow simultaneously;
(4), in Second Year the first tenday period of a month in February, at trunk 40cm place overhead, make a poison circle that 20cm is wide, around trunk one circle; The concrete preparation method of described malicious circle: cotton in two-layer gauze therebetween, gauze outside is coated with insect sticker, and gauze encloses around trunk one, and with adhesive tape, bundle is rolled in to trunk; Adopt transfusion bottle, the diversion plastic tube of transfusion bottle is looped around on gauze, and plastic tube contact gauze position is uniformly distributed with aperture, makes insecticidal solution energy uniformly penetrating on gauze; The agricultural chemicals chlopyrifos phoxim of preparing 1000 times of dilutions in transfusion bottle, the drain age velocity of transfusion bottle is 10 per minute, uses mid-March always, object is to stop the earliest a collection of willow fleautiauxia armata to be climbed the tree to lay eggs.
The inventive method is easy, effective, can make the harm of willow fleautiauxia armata reduce more than 85%.
Below in conjunction with embodiment, the invention will be further described.
Embodiment
A willow willow fleautiauxia armata method for integrated control, step is as follows:
(1), in the last ten-days period in September, when seemingly-dead property appears in adult and larva, employing 20% is killed 1500 times of liquid of chrysanthemum ester tree body is sprayed;
(2) in the middle ten days in December, willow sylvan life soil is ploughed deeply to 25cm, by hiding insect in soil, come out and freeze to death;
(3) in Second Year late January, while selecting soil relatively more wetting, in willow sylvan life, sow 3% Isofenphos methyl granule, every mu of consumption, at 500-700 gram, can infiltrate soil and poison the insect of hiding into soil with poison, can make soil getting fat again, healthy and strong willow simultaneously;
(4), in Second Year the first tenday period of a month in February, at trunk 40cm place overhead, make a poison circle that 20cm is wide, around trunk one circle; The concrete preparation method of described malicious circle: cotton in two-layer gauze therebetween, gauze outside is coated with insect sticker, and gauze encloses around trunk one, and with adhesive tape, gauze is wrapped on to trunk; Adopt transfusion bottle, the diversion plastic tube of transfusion bottle is looped around on gauze, and plastic tube contact gauze position is uniformly distributed with aperture, makes insecticidal solution energy uniformly penetrating on gauze; The agricultural chemicals chlopyrifos phoxim of preparing 1000 times of dilutions in transfusion bottle, the drain age velocity of transfusion bottle is 10 per minute, uses mid-March always, object is to stop the earliest a collection of willow fleautiauxia armata to be climbed the tree to lay eggs.
Described agricultural chemicals chlopyrifos phoxim is that Qingdao hundred standing grain Fenghua biotechnology Co., Ltds produce, total active ingredient mass content 40%; Its Chlorpyrifos mass content is 15%, and phoxim mass content is 25%, and formulation is missible oil.Also can adopt the product of other models and producer.
