Abstract
The present invention is a kind of insecticides containing four Tolfenpyrads, Rynaxypyr or bromine cyanogen insect amide, belong to chemical prevention field, it is made of four Tolfenpyrad of active ingredient, Rynaxypyr or bromine cyanogen insect amide and its auxiliary agent, has good synergistic effect to prevention lepidoptera pest especially striped rice borer.The insecticides indoor biometrics are 20 to the synergic ratio of striped rice borer:1~1:20.The present invention has synergistic effect notable, and preventive effect is good, and dosage is low, and to environment and target organisms safety, the features such as being controlled a medicine, this composition simultaneous can control other homoptera pests more（Such as planthopper, Bemisia tabaci）, have good effect to the drug resistance of medicament to slowing down striped rice borer.
Description
Technical field
The invention belongs to Chemical Control of Harmful Insects fields, and in particular to a kind of prevention lepidoptera pest, especially striped rice borer
Compounded pesticides.
Background technology
Striped rice borer（Chilo suppressalisWalker）Belong to Lepidoptera, Pyralidae, popular name borer, borer, moth
Stalk worm etc. is that one of Occurrence the most serious is endangered on China's rice, tillering stage it is aggrieved cause withered sheath, withered heart seedling,
Insect bite strain and dead ears are caused ear period is aggrieved, the general time underproduction 3%~5%, the underproduction is more than 3 one-tenth when serious.Occur in recent years
Quantity is in the situation obviously risen.Striped rice borer is in addition to hazard rice, moreover it is possible to endanger wild rice stem, corn, sorghum, sugarcane, rape, silkworm
The weeds such as beans, wheat and reed, barnyard grass, Leersia Sw.Domestic each rice region is distributed, wide but main compared with yellow rice borer and pink rice borer distribution
Will with the Yangtze river basin and on the south rice region occur heavier, reach Heilungkiang Keshan County in distribution in China north, south is to Hainan Island.If not into
The reasonable effectively preventing striped rice borer of row, China's rice injured area will further expand.
Four Tolfenpyrads are a kind of new and effective insecticides, have the characteristics that ultra high efficiency, low toxicity, low-residual, nuisanceless,
It is high to the activity of the larva of lepidopterous insects and other many pests.
Rynaxypyr, common first names health is wide, is used to prevent the Lepidopteras such as striped rice borer, rice leaf roller evil all the time
Worm, but due to the increase of dosage, rice is vertical and striped rice borer is increasingly severe to the resistance of Rynaxypyr.
Bromine cyanogen insect amide also known as cyanogen insect amide belong to ryanodine receptor inhibitor insecticides, can effectively prevent Lepidoptera
Equal pests.
So far, not yet find that four Tolfenpyrads and Rynaxypyr or the insecticides of bromine cyanogen insect amide are anti-
Control the report of striped rice borer.
