Abstract
The invention provides a film diffusing oil agent combined reagent for preventing and treating rice planthopper. The film diffusing oil agent combined reagent consists of an active ingredient, a film agent, a cosolvent and a solvent. When the reagent is used, a film diffusing oil agent is directly poured in a paddy field and dilution using water is not required. The film diffusing oil agent entering water is diffused in the form of oil films in the whole paddy field, and can climb along a rice rod, so that rice planthopper can be effectively prevented and treated, and rice borers can be prevented. The film diffusing oil agent combined reagent is a novel efficient pesticide formulation.
Description
Technical field
The present invention relates to a kind of film-spreading oil solution combination medicament of preventing and treating rice hoppers, belong to technical field of pesticide preparations.
Background technology
MTI-446, chemical name are 1-methyl-2-nitro-3-(tetrahydrochysene-3-furfuryl) guanidine, (EZ)-(RS)-1-methyl-2-nitro-3-(tetrahydrochysene-3-furfuryl) guanidine, N-methyl-N'-nitro-N''-[(tetrahydrochysene-3-furans) methyl] guanidine.Water solubility is 40g/L.This medicament have tag, strong, quick-acting height of absorption in stomach toxicity and root, the characteristics such as the lasting period is long, insecticidal spectrum is wide, and sucking insect is had excellent preventive effect, and has namely shown very high insecticidal activity at very low dosage.Be mainly used in preventing and treating aphid, leafhopper, plant hopper, thrips, aleyrodid and resistant strain thereof on the various crop such as wheat, paddy rice, cotton, vegetables, fruit tree, tobacco leaf.And carbamate chemicals for agriculture effect wide spectrum, can by tag, the stomach poison function kill pests.MTI-446 and carbamates medicament can effectively be prevented and treated for the rice fulgorid occurrence characteristic.
In recent years, the generation of China's rice hoppers is always in rising trend.Rice fulgorid adult and nymph are clustered on the stem stalk of rice clump bottom thorn and inhale juice, it is caused harm to paddy rice, inhale juice except directly stinging, make growth retardation, when serious, the rice clump is agglomerating withered, outside the dead stalk lodging in even full field, lays eggs and also can stab plant, destroy conducting tissue, hinder the nutriment viral disease of transporting and spread disease.Prevent and treat at present rice hoppers, usually adopt traditional conventional spray pattern to prevent and treat.But this conventional spray method not only takes a lot of work, time-consuming, and easily make the drift of medicine mist cause the environment around dispenser ground to be polluted.In addition because rice hoppers is mainly inhaled juice in thorn on the stem stalk of rice clump bottom, when paddy rice Feng Hanghou carries out conventional foliar spray control, not only make medicament be difficult to spray application to rice clump bottom stem stalk because the rice strain is too close, and because the drift of medicine mist, photodissociation are run off, the dosage that causes medicament to be delivered to the paddy rice base portion also reduces greatly.So with conventional spray method control rice fulgorid, the medicament availability is low, actual effect is also low.And along with the appearance of China's aging population and recruitment famine, the labour becomes rare resource just gradually, and human cost improves constantly, and agriculture production cost continues to increase; Agricultural production is obviously seasonal, and rice hoppers often needs a large amount of manpowers to prevent and treat at short notice.
At present, 201210125077.2), " 5% preparation of ether chrysanthemum ester film-spreading oil solution and operation technique research ", " 5% ether chrysanthemum ester film-spreading oil solution prepare and to the control efficiency of rice fulgorid ", " 8% Buprofezin film-spreading oil solution is prevented and treated the rice hoppers Probe into effect " patent and related article report about control rice fulgorid film-spreading oil solution has " preparation of ether chrysanthemum ester film-spreading oil solution and the application on the control rice fulgorid thereof " (application number:, ether chrysanthemum ester itself there is no internal absorption characteristic, and Buprofezin is slower action time.And ether chrysanthemum ester and Buprofezin water-soluble are relatively poor, are respectively 1ug/L and 0.9mg/L, thus medicament to make after film-spreading oil solution the valid density in water less, crystallization in Yi Zaishui and lose effect.When medicament after the rice stem base portion is assembled on kill rice fulgorid after conducting; protect without medicament but make in the paddy rice body because active ingredient concentration is low; rice fulgorid is migratory pest, causes rice fulgorid can not effectively prevent and treat the insect that the later stage migrates after the death of tagging.The conventional pesticides such as Buprofezin, ether chrysanthemum ester, Imidacloprid, use separately for a long time at present, and rice fulgorid has been produced certain pesticide resistance, causes drug effect to descend.
Summary of the invention
For take a lot of work in present rice fulgorid preventing and controlling, time-consuming, consumption is seriously polluted greatly, the agricultural chemicals availability is low, actual control efficiency is low, reduce the consumption of single dose MTI-446, delay the problem of drug-fast generation or development, a kind of saving of labor who the object of the present invention is to provide, laborsaving, environmental contamination reduction, raising agricultural chemicals availability, the actual control efficiency that improves, and the film-spreading oil solution combination medicament of the anti-paddy rice borer of holding concurrently when realizing the control rice fulgorid.
The present invention realizes that the technical scheme that above-mentioned purpose is taked is: a kind of film-spreading oil solution combination medicament of preventing and treating rice hoppers comprises the component of following weight proportion:
