Description
Technical field
The invention belongs to compounded preparation of pesticide and preparation method thereof technical field.The present invention can be directly used in the particularly main soil insect in the tobacco planting process (mole cricket, cutworm, wireworm, grub etc.) of the general crops of control.During soil insect, adopt the back earthing of spreading manuer in holes in the control tobacco planting process.
Background technology
(a) present, high-toxic pesticide causes a lot of problems, and particularly the dispenser personnel poison and the residual problem that exceeds standard of agricultural product.On the other hand, United Nations Environment Programme and Food and Agricultural Organization of the United Nations formulate in Rotterdam on September 10th, 1998 " about in international trade to Rotterdam's pact of some hazardous chemical and pesticide recovery prior informed consent program " (being called for short " Rotterdam's pact " or " PIC pact "), China's signature in 1998 adds, and comes into force due on February 24th, 2004 approximately.This pact is shortlisted acephatemet, parathion-methyl (parathion-methyl), parathion (1605), nuvacron, phosphamidon.As containing the residual of these agricultural chemicals in the agricultural products in China, certainly will have a strong impact on the reputation of outlet and agricultural product, it is imperative to stop using.
(b) to substituting the requirement of medicament: effect should be not less than replaced medicament; Use cost should be high more not too many than replaced medicament; Low to person poultry toxicity's requirement, can not be high drugs kind; Influence to environment can not be bigger than replaced kind, mainly is natural enemy risk and aquatile risk; Development of drug resistance speed to insect will have corresponding assessment; The peasant grasps understanding easily.
(c) chlorophos is a kind of hypotoxicity agricultural chemicals, the wide organophosphorus insecticide of insecticidal spectrum.In weak lye, become dichlorvos, but unstable, very fast decomposition failure.Insect there is very strong stomach poison function, has action of contace poison concurrently, plant is had permeability, but inhale conduction in not having.Be applicable to the pests with chewing mouthparts of crops such as tobacco, water paddy and wheat class, vegetables, tea tree, fruit tree, mulberry tree, cotton, duckweed, reach the control of animal parasite, sanitary insect pest etc.The use of chlorophos list agent has the effective component content height, the cost height, and easily deliquescence caking and reduction drug effect are used inconvenient shortcoming, and be only effective to the pests with chewing mouthparts of crop.
Phoxim is the high-efficiency low-toxicity organophosphorus insecticide, tagging and stomach toxicity, and no systemic action, insecticidal spectrum is wide, and the power of knocking down is strong, and is very effective to lepidopterous larvae.Use in the field, because of to photo-labile, very fast decomposition failure, so the longevity of residure is very short, labile unfavorable factor, residual danger is minimum, the general longevity of residure 2-3 of foliar spray days; But this medicine applies in the soil, can effectively avoid its unfavorable factor to the easy decomposition failure of photo-labile, and the term of validity can reach 1-2 month.Be suitable for preventing and treating soil insect, particularly the larva to the multiple lepidoptera pests of crops such as the tobacco of causing harm, peanut, wheat, paddy rice, cotton, corn, fruit tree, vegetables, mulberry, tea has special effect, worm's ovum also there is certain lethal effect, also is suitable for preventing and treating warehouse and sanitary insect pest.
The use of phoxim list agent has the effective component content height, and is the cream preparation of making solvent with environmentally harmful toluene and dimethylbenzene, and is very effective to lepidopterous larvae.At present, the composite cream preparation of making solvent with environmentally harmful toluene and dimethylbenzene of being more common in of chlorophos and phoxim, meaningless to environment.
The composite advantage of chlorophos and phoxim:
1, widens the pesticide control spectrum: can learn from other's strong points to offset one's weaknesses between each single agent, have complementary advantages, and enlarge the control spectrum and the scope of application of agricultural chemicals;
2, increase insecticidal effect.
Toxicity, poisoning or residual when 3, reducing use: both increase malicious phenomenon at composite nothing, improve safety in utilization, have surpassed to reduce the degree that consumption can reach.As normally used chlorophos and phoxim emulsifiable concentrate; not only labour intensity is big when using spraying; and the used solvent of missible oil is toluene or dimethylbenzene; all can and do deposits yields pollution and residual after the use to bad border; and the composite solid particle of chlorophos and phoxim or the exploitation of microparticle formulation; thereby reduced the application of toluene or dimethylbenzene; back content is low owing to be mixed; further reduced toxicity; can directly spread fertilizer over the fields with hand safely, on crops, reach the residual quantity in the environment after corresponding reduction is used big Tanaka.
4, save dosing, reduce the control cost.Generally can reduce dosage 20-30%.
Summary of the invention
