Abstract
The invention discloses a pesticide component containing fipronil and the application thereof. The invention is composed of component A and component B, wherein, the component A is the fipronil, the component B is composed of any one of thiodicarb, isoprocorb or metolcarb, wherein, the component B also comprises auxiliary materials, and the component A and the component B form a compound dispensed component according to the mass proportion of 0.1 to 10 shares: 99.9 to 90 shares. The compound dispensed component can be made into various application dose types, and the dose types comprise water dispersion granule, wettable powder, suspending agent and emulsifiable oil. The cost is low, the dosage is low, the prevention effect is good, the durable period is long, the use is convenient, and the residual on the crop is less; according to the adjustment of the compound dispensing proportion of the medicine and the auxiliary materials, the characteristic that the prevention effect of the invention can be enhanced by 1.5 times can be reached, and the invention has the synergic function for pest killing, and is used for rice planthopper prevention.
Description
Technical field
The present invention relates to a kind of composition pesticide, concrete relating to is used for a kind of insecticides and application thereof that contains fluorine worm nitrile of rice hoppers control.
Technical background
The two prestige of sulphur belong to carbamyl oximes insecticide, the insecticidal activity height, and toxicity is low, mainly is stomach poison function to insect, also has certain ovicidal action, and rice planthoppers of rice, rice leaf roller and two, paddy stem borer all have fabulous control.
Mobucin and meta-tolyl-N-methylcarbamate (MTMC): all belong to the substituted-phenyl carbamate compounds, desinsection is identical, all water rice hopper is prevented to give prominence to, and action of contace poison is strong, soup is rapid, still the long defective of effect is held in existence.
According to national agricultural [technology service centre data show, climatic variation in recent years, the worm source influence of constantly moving into overseas, the south China of present China, southwest, the south of the lower reaches of the Yangtze River all general large tracts of land in every year takes place, area only took place in 2007 to be reached more than 3,500 ten thousand mu, increased more than 50% with 2006, and occurrence scope is more and more wider, resistance is increasing, the generation overlap phenomenon is serious, and procreation and migration are fast, and great outburst situation in some areas is very common, at present since above-mentioned single agent prescription hold and imitate and quick-actingly do not reach unification, and single agent resistance power is big, can not continue to use, and has caused large tracts of land to be subjected to plague of insects loss serious, the situation is tense, and the composite kind that existing market is sold has: Imidacloprid and Buprofezin composite, the harm of the composite uncontrollable plant hopper of dichlorvos and dimehypo.But these composite kinds exist consumption very big, and the agricultural chemicals remaining quantity is big, waste extremely seriously, can't play good shortcomings such as control efficiency again.
Summary of the invention
It is low to the purpose of this invention is to provide a kind of cost, and control efficiency is good, and the lasting period is long, and is easy to use, a kind of insecticides that contains fluorine worm nitrile that the residue that crops retain is few.
Another object of the present invention provides the application of the insecticides that contains fluorine worm nitrile.
Technical scheme among the present invention is to solve like this: a kind of insecticides that contains fluorine worm nitrile, substantive distinguishing features that it is outstanding and obvious improvement are to contain by component A and component B to be formed, its described component A is a fluorine worm nitrile, described component B is any one composition in the two prestige of sulphur, Mobucin or the meta-tolyl-N-methylcarbamate (MTMC), wherein component (B) also includes auxiliary material, is component A in quality than ratio: component B=0.1 part～10 parts: form complex composition for 99.9 parts～90 parts.
Any described a kind of application that contains the insecticides of fluorine worm nitrile of a kind of claim 1-7, substantive distinguishing features that it is outstanding and obvious improvement be in above-mentioned said component A and component B in quality than ratio weigh mix after, filler in water or the auxiliary material is mended into becoming 100 parts, can make different application forms, its formulation comprises: water dispersible granules, wetting powder, suspending agent, missible oil.
Described fluorine worm nitrile is a kind of Phenylpyrazole insecticides, to insect with stomach toxicity and tagging, systemic action is main, it is again never poison, desinsection is general wide, can be used for the multiple insect pest of Different Crop, wherein in recent years in the rice insect pest control, rice fulgorid and two, paddy stem borer are all had fabulous control, and the lasting period is long.
Through overtesting, now develop the AB composition and be used for the plant hopper control, the A composition is a fluorine worm nitrile in this Chemical composition that, the B composition is the two prestige of sulphur, Mobucin and meta-tolyl-N-methylcarbamate (MTMC), single agent use cost that the AB composition has reduced the A composition has effectively improved the quick-acting of A composition again, and has improved the persistence of B composition.Reduced use cost, the preventive effect great raising of having got back, not only preventive effect is outstanding, and is beneficial to and promotes the use of.
In order to prevent and treat the rice planthoppers of rice insect pest, be that the two prestige of sulphur, Mobucin and meta-tolyl-N-methylcarbamate (MTMC) have been carried out mutual composite synergy research with composition A fluorine worm nitrile, composition B, rice hoppers has been carried out Toxicity Determination and used the prescription screening with different proportionings.Test medicine provides former medicine for producer, this experiment adopts growth rate method to carry out, and be mixed into contrast with equivalent aqua sterilisa and medium, calculate virulence equation and lethal concentration of 50 EC50 with method of least squares, calculate different proportioning synergy ratio (SR) toxicity indexes of medicament and the toxicity index that the abundant method of Sun Yun is calculated medicament according to the Wadley method, the co-toxicity coefficient of using with (CTC method), wherein the abundant method of Sun Yun is calculated the toxicity index of medicament, the co-toxicity coefficient of using with (CTC method), co-toxicity coefficient is an antagonism less than 80,80～120 is summation action, is synergistic effect greater than 120.
