Description
Technical field
The present invention relates to a kind of agricultural chemicals of preventing and treating small brown rice planthopper, particularly a kind of granule that is used for controlling Laodelphax striatella in wheat fields.
Background technology
In recent years, small brown rice planthopper was taken place rampant in China paddy and wheat crop rotation district, cause it to break out greatly as vector-borne stripe disease year after year, caused the paddy rice underproduction, and rice quality descends.
Small brown rice planthopper all can survive the winter in the most of area of China.After the rice harvesting in late fall, the wheatland of mainly moving into is survived the winter, the rice seedling bed or early plant the paddy rice of causing harm in the rice field moved into again after the wheat harvesting in the 2nd year, and propagate the stripe virus disease poison.Except that factors such as weather, crop varieties and cropping system, another main cause that small brown rice planthopper breaks out is that the special effect agent Imidacloprid to the past has produced pesticide resistance, make and after Imidacloprid is used in the rice field, still have under a large amount of small brown rice planthopper survivals, and move in the wheatland and survive the winter, become the 2nd year big radix that takes place.Annual May early and middle ten days, small brown rice planthopper is in low age nymph peak period in the wheatland, is the favourable period of control, but has following difficulty wheatland control small brown rice planthopper this period, first, small brown rice planthopper is lighter to the harm that wheat is caused, and is difficult to cause peasant's attention; The second, at present be used in producing to prevent and treat that the medicament of small brown rice planthopper is most of is formulations such as missible oil, wetting powder, require to convert water spray and use, under the wheatland environment, the water source is far away, the water intaking difficulty; Three, this moment, wheat colony was big, and the wheat leaf is folded mutually to hide, strongly fragrant degree of covering height, and small brown rice planthopper is got food and causes harm in the middle and lower part of wheat, even the big yield spraying also is difficult to soup is delivered to the straw bottom, the small brown rice planthopper polypide is difficult to contact medicament.In view of above 3 points, the control of wheatland small brown rice planthopper often can't effectively be implemented, and poor effect.
The conventional method of control small brown rice planthopper, control stripe disease is the striatellus imago of moving into from wheatland in the control of rice seedling bed phase at present.Because the anti-drug resistance of adult is higher than the low age nymph far away, must increase substantially the dosage of medicaments such as Imidacloprid; And this moment small brown rice planthopper continuously from the wheatland rice seedling bed of moving into, control pressure is big, is " three days anti-two " in actual production, or even " one day anti-once ", makes that the pesticide dosage on the unit are increases rapidly.This extraordinary agricultural chemicals usage amount and occupation mode will cause small brown rice planthopper to produce even more serious pesticide resistance, and the small brown rice planthopper in the rice seedling bed of moving into is before being killed by medicament, often directly or by laying eggs propagate the stripe virus disease poison, therefore still be difficult to effectively control the generation of stripe disease.
The chemical name of chlopyrifos is O, O-diethyl-O-3, and 5,6-trichloro-2-pyridyl phosphorothionate, international title chlorpyrifos, U.S. Dow chemical company succeeds in developing nineteen sixty-five, is one of pesticide species of output maximum in the world so far.Pure product are white crystalline solid, relative density 1.398, fusing point 42.5-43 ℃, saturated vapor pressure 2.4 X 10 in the time of 25 ℃
-3Pa is soluble in most of organic solvents.
The chemical name of dichlorvos is O, O-dimethyl-O-(2, the 2-dichloroethylene) phosphate, and international title dichlorvos is a kind of organophosphorus insecticide of efficient, quick-acting, wide spectrum.Pure product are colourless to amber color liquid, and fragranced is arranged, relative density 1.415, and boiling point is 35 ℃ (6.667Pa), saturated vapor pressure 9.9Pa in the time of 40 ℃ can be dissolved in most of organic solvents.
That chlopyrifos and dichlorvos all have is stifling, stomach toxicity and action of contace poison, and biting mouth parts insect and sucking insect are all had good control efficiency.Domestic existing about chlopyrifos and the atgard mixed patent application that becomes cream preparation.As CN1251261 " a kind of composite formula insecticide " and CN1256866 " insecticide emulsifiable concentrate that contains chlopyrifos and dichlorvos ", these two patent applications all are cream preparations, and all do not classify the wheatland small brown rice planthopper as controlling object.
