Abstract
A composite miticide in the form of microemulsion, emulsified oil, solution, or suspension contains abamectin and hexythiazox in weight ratio of 1: (2-14). Its advantages are high and durable effect and low cost.
Description
Technical field
The invention belongs to the composition pesticide field, a kind of specifically miticide composition that is used to prevent and treat fruit tree and the insect pest of crops mite class.
Background technology
Mite pest is commonly called as two spotted spider mite, is one of main insect pest of crops such as fruit tree, cotton, vegetables, not only has a strong impact on the growing way of fruit tree and crops, and damages output and the quality of fruit, vegetables, cotton, reduces peasant's economic benefit greatly.Because the generation algebraically of mite class is many, breeding spreads fast, and many generations alternately grow up, thereby the control quite difficulty of getting up, again because mite class and general agricultural pests physiological mechanism different, general efficient pesticides does not almost have preventive and therapeutic effect to the mite class.In the past, it is less that China is used to prevent and treat the specialized acaricide of mite class, generally is to use dicofol, tetradiphon, and isocarbophos, mixture of azacyclotin and they and diesel oil etc. etc., control efficiency is undesirable.The twentieth century end, develop some abroad and be used to prevent and treat the new varieties of mite class, as Hexythiazox, pyridaben, propargite and Avermectin etc., these new products are having its original effect preventive and therapeutic effect better aspect the harm of control mite class, but also exist deficiency in some aspects.
Avermectin (abamectin) claim avermectin again, it is a kind of Biocidal miticide newly developed, Avermectin has stomach toxicity and action of contace poison to mite class and insect, what mechanism of action was different with general insecticide is to disturb the neurophysiology activity, stimulate to discharge γ-An Jidingsuan, and aminobutyric acid has inhibitory action to arthropodan nerve conduction.Permeability is strong, and soup is sprayed onto to infiltrate rapidly behind the plant leaf surface and forms numerous miniature anther sacs in the mesophyll, the adult of mite class and the larval feeding of insect with contact soup after paralysis symptom appears immediately, inertia, do not get food, death in 2-4 days.Be applicable to crops such as vegetables, oranges and tangerines, cotton, be used to prevent and treat diamond-back moth, leaf miner, two spotted spider mite etc.
The weak point of Avermectin is the effect of not killing the acarid ovum.
Use mite time-likes such as Avermectin control two spotted spider mite, rust mite the earliest, generally add 1.8% Avermectin 20-33 milliliter (valid density 3.6-6 mg/litre) with 1.8% Avermectin 3000-5000 times liquid or per 100 premium on currency.But because the drug-fast increase of insect pest now increases greatly with concentration.
Hexythiazox (hexythiazox) trade name hexythiazox, it is the novel miticide of a kind of thiazolidine ketone, and the plant epidermis layer is had penetrability preferably, but inhales conduction in not having.This agent has strong ovum extremely, kills the children if the characteristic of mite has the effect that inhibition is hatched to the ovum that female adult worm produced that touches soup the harmful mite of various plants.This medicine belongs to non-response to temperature miticide, and the effect of using when high temperature or low temperature does not have significant difference, and the lasting period is long, and drug effect can keep about 50 days.Its weak point is not kill into the mite activity, so the drug effect performance is slower.This medicine is good to the tetranychid preventive effect, to rust mite, the anti-heterodyne of goitre mite.Applicable crops is oranges and tangerines, apple, cotton, hawthorn etc.
Because there are above-mentioned deficiency in Avermectin and Hexythiazox aspect the control mite class, particularly current China peasant drug level is low, not science, often use same pesticide species continuously, and improve constantly and use concentration, cause the resistance level of insect pest to grow with each passing day, control efficiency obviously reduces.And the increase of insect pest resistance is had to again improve and is used concentration, and certain areas peasant's working concentration has reached the degree of only diluting 1000 times at present.
One of solution route that the solution insect produces anti-medicine to single pesticide species is that the agricultural chemicals that two or more is different carries out compounded combination, if experimental results show that synergy mutually between each component of composition, said composition promptly can be used as single agent that replacement produced resistance and develops and utilize.At present, the composition of insecticide aspect is varied, but aspect miticide, the exploitation direction of known miticide composition is mainly still in order to reduce acaricidal production cost and unit price, multiselect is acaricidal composite with other with diesel oil or low-cost dicofol etc., though it is this series products can adapt to the demand of current rural purchasing power, not ideal enough to the control efficiency of mite class.Miticide composition is the complex composition of main component as adopting dissimilar efficient miticides such as Avermectin and Hexythiazox preferably, does not occur as yet, does not at home and abroad also appear in the newspapers in the document.
Summary of the invention
The objective of the invention is provides a kind of novel control efficiency comparatively ideal miticide composition in order to overcome the deficiency that existing miticide exists to market.The inventor is according to the pests occurrence rule of mite class and prevent and treat present situation, by the analysis and research of Avermectin and these two kinds of acaricidal characteristics of Hexythiazox are thought, the product type of Avermectin and Hexythiazox, structure, performance characteristics, acaricidal action mechanism etc. are all inequality, and it is killing into mite and is killing and can carry out complementation aspect the ovum, use its compounded combination, will obtain desirable control efficiency.Indoor preliminary test shows that after both carried out compounded combination, its coefficient of synergism can reach 140～170%, and obvious synergistic effect is arranged, thereby selects for use miticides such as Avermectin and Hexythiazox to carry out compounded combination, and the development of new miticide is feasible.
Technical solutions according to the invention are a kind of novel miticide compositions, it is characterized in that it contains Avermectin and Hexythiazox etc. and kill mite active ingredient.
Test shows that the usage ratio in the miticide composition of the present invention between active ingredient Avermectin and the hexythiazox has a direct impact the control efficiency of said composition to the mite class, therefore screening between the two also be one of major technique feature of the present invention with magnitude relation.By assay to both compound synergic coefficients (co-toxicity coefficient) and control efficiency, the inventor confirms, weight consumption ratio in this miticide composition between Avermectin and the Hexythiazox should be: Avermectin: Hexythiazox=(0.1～5): (0.1～20) (by the weight ratio of folding 100% former medicine, as follows);
Part by weight is preferably: Avermectin: Hexythiazox=1: complementation and synergistic effect are better in (1～50), this scope;
Preferred part by weight is: Avermectin: Hexythiazox=1: coefficient of synergism all is higher than 140% in (2～14), this scope;
Best part by weight is: Avermectin: Hexythiazox=1: coefficient of synergism all is higher than 160% in (4～6.5), this scope.
When Avermectin: when the part by weight of Hexythiazox was 1: 5, coefficient of synergism was 174.5%.
Miticide composition of the present invention is except that containing active ingredients such as Avermectin and Hexythiazox, can add suitable all kinds of usual auxiliaries, solvent or carrier, formulations of pesticide processing method according to routine, as auxiliary agent, solvent, carrier and the processing method of being introduced in " formulations of pesticide process technology " (Liu Bulin work), be processed into suitable formulation, as microemulsion, missible oil, soluble liquid, suspending agent and other common formulations.
The suitable formulation that miticide composition of the present invention is recommended is a microemulsion, and its processing method is as follows:
Content of effective generally can be controlled in (0.2～20) % in the miticide composition of the present invention.According to the rule of pesticide processing, active constituent content is high more in the formulation, helps saving the consumption of auxiliary elements such as auxiliary agent, solvent, carrier more, reduce raw material and carrying cost, reduce environmental pollution, therefore, active constituent content can also be higher in the miticide composition preparation of the present invention.Because the most preferred dosage form that the present invention recommended is a microemulsion, its environmental pollution is slight, consider that China peasant medication custom generally is to use after adding 1000～2000 times of dilutions of water, therefore the inventor to recommend the active constituent content scope be 1～5% better, the content range that when active constituent content is 3%, uses for the optimum peasant.
Because the type as the Avermectin of the main active ingredient of miticide composition of the present invention and Hexythiazox is different, the source is different, the structural behaviour and the mechanism of action and all inequality to the prevention and treatment range of mite class, its complex composition is processed as novel miticide, to obtain the remarkable result of two aspects, one is that significant synergistic effect is arranged; Another is to carry out complementation in many-side.
The inventor adopts the blade infusion process, the miticide composition of the present invention of different Avermectin and Hexythiazox usage ratio being killed the virulence of citrus red mite tests, and calculate coefficient of synergism (co-toxicity coefficient), the result shows, in usage ratio scope of the present invention, synergistic effect is all arranged, particularly when the part by weight of Avermectin and Hexythiazox 1: in the time of in (2～14) scope, coefficient of synergism is 140～175%, and significant synergistic effect is arranged.
The main active ingredient Avermectin and the Hexythiazox of miticide composition of the present invention have tangible complementation, Avermectin has very high activity to the children as if mite, one-tenth mite, and it is very low to the activity of mite ovum, Hexythiazox is just in time opposite, it has strong killing action to the mite ovum, and to one-tenth mite nearly unavailable, but can cause that female one-tenth mite is sterile, both complementations aspect effect worm attitude; Avermectin is active high to becoming mite, shows good quick-acting, and Hexythiazox almost to becoming mite not have direct killing action, becomes mite still in activity after the medication, and quick-acting is poor, and both can be complementary; Because Avermectin is to the ovum weak effect, thereby the lasting period is short, has only 15 days, the main effect of Hexythiazox is to kill ovum and sterile effect, and after the medication, insect population quantity reduces gradually, and recovering also needs certain hour, and the lasting period can reach 30～50 days, and both are just complementary; The acaricidal activity temperature influence of Avermectin is big, acaricidal activity height when temperature is high, and acaricidal activity was also low when temperature was low, and the acaricidal activity of Hexythiazox temperature influence not substantially, both have stronger complementation; With Avermectin and Hexythiazox is the miticide composition that main active ingredient is re-dubbed, and can kill ovum and can kill mite again, has improved quick-acting, has prolonged the lasting period, and can also can show effect preferably when low temperature.
The miticidal effect of miticide composition of the present invention is quite desirable.Use the miticide composition of the present invention of active ingredient 3%---i.e. 3% A Wei hexythiazox micro-emulsion, dilute 1500 times of medications, control efficiency generally can reach more than 93%, even near 100%.Contrast 1500 times of medications of 1.8% Avermectin dilution, control efficiency is lower about 10～20 percentage points than the present invention.1500 times of 5% Hexythiazox (hexythiazox) dilutions, control efficiency is lower about 10 percentage points than the present invention.
Under identical preventive effect, present composition use cost hangs down 5～10% than single with Avermectin or Hexythiazox (hexythiazox).
The preferred dosage form that the present invention recommends is a microemulsion, it replaces the oil base form with water base form, and having reduced with dimethylbenzene is the consumption of the organic solvent of representative, has reduced the pollution to environment, meet China's agricultural chemicals developing direction, so miticide composition promotion prospect of the present invention is wide.
Miticide composition of the present invention not only is used to prevent and treat the mite class, and it also has the significantly double effect of controlling to other fruit tree, grain, cotton, vegetables insect pest.
