Thus, the compounded preparation is mainly used for preventing and curing forest defoliators, overcomes the defect that the spraying method is easy to affect by weather variation and solves the difficulty that application can not be realized in large-area industrial raw material forests because forest trees are high.
Description
Technical field
The present invention relates to a kind of compounded preparation of pesticide, relate in particular to a kind of pesticide for preventing and curing forest defoliator by trunk injection complex preparation.
Background technology
Be that the forest defoliator is caused harm the most rampant period annual summer and autumn.The insect generating period is short, insect density is high, food leaf amount is big, harm is very serious, can eat leaf with nothing left, makes it to stop growing even withered because of forfeiture photosynthesis ability.
The defoliator of broadleaf tree mainly contains slug moth (oriental moth, green slug moth, thosea siensis), boat moth (fan boat moth, bateau moth, Closteraanastomosis L.), yellow leaf curl snout moth's larva.These insects enter the mature larva phase in summer, part begins to pupate, worm strain rate is more than 80%, about 20 of average strain insect density, indivedual regional strain insect density may surpass hundred, generally form before and after the beginning of autumn with the slug moth second generation, boat moth, the yellow leaf curl snout moth's larva third generation are the main defoliator peak period of causing harm.As half-hearted control, then can bring very big harm to production of forestry.
The conventional control method has three kinds: the one, the following young growth of new afforestation and life in 3 years is preferably adopted the method for artificial seizure, to extract pieces of an egg and cocoon (pupa).The 2nd, should adopt high-pressure fog machine spray medicine to " green channel " trees and woods in blocks, catch insect to be in the best opportunity of newly hatched larvae phase, kill with medicine liquid spray.The 3rd, can adopt root dispenser method to behind the house perennial tall and big trees before the room, promptly dig near the earth of opening the trees ' root earlier, around main root, prick 8～10 holes (dark about 2 centimetres) with iron nail, irritate agricultural chemicals stoste then, relatively be fit to " four is other " trees and use.These three kinds of methods all have their weak point, and first method is only used when trees young growth or trees are short and small and needed a large amount of labours.Second method is only better used in the forest land that can lead to the vehicles, and the forest land environment is polluted and kills the natural enemy of forest damage by disease and insect.The third method also is to need great amount of manpower to be not suitable for large tracts of land to use, and will find a kind of control efficiency sustainable high efficiency control preparation.
Summary of the invention
The objective of the invention is to: for production of forestry and afforestation management provides a kind of " efficient, saving, environmental protection " trunk punching dispenser forest defoliator Prevention Technique, the control medicament of " efficient, low toxicity, hold effect " is provided for this Prevention Technique, to solve the practical difficulty in production of forestry and the management, overcome the shortcoming that spraying method is subject to Changes in weather influence, solve forest tree height and reach the difficult problem that the large tracts of land cycle industrial material forest can't dispenser greatly.
Pesticide for preventing and curing forest defoliator by trunk injection complex preparation of the present invention is made by weight percentage by following component:
1-thiosulfonic acid sodium base-2-dimethylamino-3-thiosulfonic acid base propane is the desinsection list, 5-30%
2-dimethylamino-1, the two thiosulfonic acid sodium base propane of 3-are dimehypo, 10-35%
Cosolvent 0-2%
Activator 0-1%
Toner 0-0.05%
Surplus is a water.
Compounded preparation of pesticide compound method of the present invention is: get the raw materials ready by said ratio, stir in the aqueous solution with solid powdery desinsection list adding part dimehypo, obtain mix suspending solution, again this mix suspending solution and cosolvent, activator, toner are slowly added in the aqueous solution of another part dimehypo, add fashionable will evenly the stirring, until whole dissolvings, promptly.
Cosolvent of the present invention is organic acid and sodium salt or amides compound.
Activator of the present invention is ammonium sulfate or ammonium chloride or ammonium hydroxide.
Toner of the present invention is toner or inorganic toner.
Compounded preparation of pesticide of the present invention possesses following characteristic:
1, be aqueous solvent, when using be former medicine use need not the dilution.
2, insecticidal spectrum is wide.Can be used for preventing and treating multiple defoliator, borer pest on the forest, aphid, leafhopper, plant hopper, thrips, mite class etc. are also had good control efficiency.
3, has multiple insecticidal action.Insect is had very strong stomach poison function, also have certain fumigation action, certain food refusal effect is arranged.Adult, larva, ovum are had lethality, and existing quick-acting has long lasting effect again, thereby when using in the field, the optimum period for applying fertilizer is long, and control efficiency is stablized.
4, mechanism of action is special.This product is a sandworm toxin insecticide, is the chemical constitution according to nereistoxin, bionical synthetic insecticide.Though insecticides such as nereistoxin insecticide and organic phosphor, carbamate, pyrethroid belong to never poison together, the mechanism of action difference.Its site of action is a cholinergic synapse, and the moon is held back neural normal delivery and made the nerve of insect not produce melon to external irritant, and after the insect contact or getting the food medicament, very fast drowse, the paralysis of polypide is until death.But polypide does not have spasm or overwrought symptom after poisoning.Because the difference of action target, there is not the cross resistance problem with insecticides such as organic phosphor, carbamate, pyrethroids, in pest control, do not produce the phenomenon of cross resistance yet, therefore the insect that above-mentioned three insecticides are developed immunity to drugs adopts the nereistoxin insecticide control that good effect is still arranged.
5, low toxicity and low residue.So far the kind that develops, all in low toxicity and medium malicious scope, safe in utilization to the toxicity of people and animals, birds, fish and aquatic animal.Little to environmental influence, use the back and decompose easily at natural world, there is not residual toxicity.
6, fallen leaves even dead can appear after having harmful effect such as ligustrum lucidum ait, southern magnolia etc. to use to certain some seeds and crop.The seedling of brassicaceous vegetables such as crops Chinese cabbage, wild cabbage is to this product sensitivity, and is more responsive when summer high temperature or plant growth are more weak; Beans, cotton etc. are responsive especially to this product, are subject to poisoning.
7, be mainly used in the control of forest defoliator, be adapted to the forest defoliator control of forestry and gardens department.
