Abstract
The invention discloses pesticide paste for controlling longicorn beetles. The pesticide paste comprises the following components in parts by weight: 1-20 parts of imidacloprid, 10-40 parts of dichlorphos, 3-10 parts of an additive, 0.5-5 parts of a thickening agent, 5-20 parts of water and the balance being fillers. The pesticide paste is injected into holes damaged by the longicorn beetles by virtue of a silica gel gun to kill the longicorn beetles in the holes by virtue of the contact toxicity and the systemic property of the imidacloprid and the fumigation property of the dichlorphos. The pesticide paste is an effective chemical agent for controlling forest pests, longicorn beetles, has a relatively good control effect on anoplophora chinensis, anoplophora glabripennis, apriona germari and batocera horsfieldi, and has a special effect on the apriona germari. The pesticide paste has a remarkable synergistic effect, has the contact toxicity and the fumigation property, is low in environmental pollution due to no organic solvent, and is worthy of popularization and application to control on the forest pests, longicorn beetles.
Description
Technical field
The invention belongs to Pesticide formulation field, specifically relate to a kind of agricultural chemicals paste of preventing and treating longicorn.
Background technology
Longicorn is the general name of coleoptera Chrysomeloidea Cerambycidae, and it becomes polypide to be oval tubular, and back is slightly flat; Feeler raw in feeler base knurl, has the function that feeler is freely rotated and be covered in backward polypide back.Its larva moves in timber, and forest is worked the mischief.Roundheaded borer is survived the winter in the trunk of killed trees, moth food came into play after March in next year, most larvas are cut a hole growth 4cm in tree, the circle emergence hole of the pupa chamber of wide 2-3cm and straight-through epidermis, in the time that temperature liter reaches more than 15 DEG C, start to pupate, complete May and pupate, its, various places were different in size in pupa time, general 20-30 days, then turns into adult.Female male imago all one's life can mating repeatedly.Generally, in fine day mating, female worm is accustomed to laying eggs on the master of trunk bottom, side shoot, and late June to early July is egg production peak time.
Longicorn is plant-feed insect, often endangers most of woody plant, as plane tree, maple, paper mulberry, pine tree, willow, cypress, willow, elm, mandarin tree, apple tree, oriental cherry, Malus spectabilis, peach etc., also endangers some herbaceous plant.
Longicorn is the most serious period with larva to causing harm of plant, although adult is owing to laying eggs, taking food branches and leaves, also can cause infringement more or less, general and not serious.Trees inside is eaten by the moth of larva, usually hinders their normal growth, slackens the growing way of trees, shortens the trees life-span, reduces timber yield, even can cause the withered and dead of whole trees.In addition, some trees Chang Yi of being eaten into food cause the intrusion of germ and insect, are very easily rolled over by large wind.Therefore, there are every year a lot of trees to lose economic worth because of causing harm of longicorn.
At present, the method for control forestry pest longicorn mainly contains spray-on process, trunk injection, trapping method, catches and kills adult method, ovicidal method and hook and kill larva method.But these methods have certain limitation substantially, can not reach desirable control efficiency, for example spray-on process, spray organic phosphates, carbamates and pyrethroid insecticides in longicorn emergence peak period and all longicorn is had to certain effect, but because the emergence period of longicorn is very irregular, interior emergence at one time, therefore, spray-on process effect is unsatisfactory.Trunk injection, sometimes can cause certain injury to trees, and generally add volatile organic solvent in medicament, and after solvent evaporates, medicament just can not freely conduct in trees body.Other several method is also all not fully up to expectations.
Inventor is by studying the pests occurrence rule of forestry pest longicorn and the method for preventing and treating for a long time, find farm chemical ingredients to do paste making agent, use silica gel gun that agricultural chemicals paste is injected to the inside, duct after longicorn harm, then around duct seals with agricultural chemicals paste, it is splendid that the method is used for preventing and treating longicorn effect, is worth further promotion and application in longicorn control in forestry, gardens.
Summary of the invention
The object of this invention is to provide a kind of agricultural chemicals paste of preventing and treating longicorn, this agricultural chemicals paste synergistic effect is remarkable, have concurrently tag, systemic activity and fumigation activity, do not add organic solvent, reduce the pollution to environment, easy to use, be worth very much promotion and application in control forestry pest longicorn.
The present invention is achieved through the following technical solutions:
An agricultural chemicals paste of preventing and treating longicorn, is characterized in that: the parts by weight of the each component of described agricultural chemicals paste are: Imidacloprid 1-20 part, dichlorvos 10-40 part, auxiliary agent 3-10 part, thickener 0.5-5 part, water 5-20 part, filler complement to 100 parts.
In described agricultural chemicals paste, the ratio of weight and number of Imidacloprid and dichlorvos is 2: 1-1: 32.
As preferably, in described agricultural chemicals paste, the ratio of weight and number of Imidacloprid and dichlorvos is 1: 16.
One or more in described auxiliary agent castor oil polyoxyethylene ether, polyoxyethylene nonylphenol ether, styryl phenyl polyoxyethylene poly-oxygen propylene aether, aliphatic alcohol polyethenoxy polyoxypropylene graft copolymer, triphenylethylene base phenyl APEO, calcium dodecyl benzene sulfonate, sodium lignin sulfonate, lauryl sodium sulfate, polyoxyethylene nonylphenol ether phosphate and aliphatic alcohol polyoxyvinethene phosphate ammonium salt.
Described thickener is one or more in xanthans, gum Arabic, Magnesiumaluminumsilicate and polyvinyl alcohol.
Described filler is one or more in diatomite, attapulgite, bentonite, kaolin, potter's clay, precipitated calcium carbonate, lignin, corn starch and white carbon.
Agricultural chemicals paste of the present invention can effectively be prevented and treated longicorn beetle, anoplophora glabripennis, mulberry longicorn or batocera horsfieldi, especially mulberry longicorn is had to special efficacy.
The present invention possesses following beneficial effect:
1, in this agricultural chemicals paste, Imidacloprid and atgard mixed combination have notable synergistic effect, have improved the control efficiency to longicorn, have reduced cost accounting.
2, this agricultural chemicals paste processing is simple, is applicable to large-scale production and popularization, and does not add volatile organic solvent, safer to trees and environment.
3, this agricultural chemicals paste injects the inside, longicorn duct by silica gel gun, and the pesticide imidacloprid of existing action of contace poison can kill the longicorn of the inside, duct; There is again the dichlorvos of tool fumigation action, then will after potential close, can also make the longicorn of the inside fatal.
