The pesticide of the compoundings such as Cupric sulfate is applied in agricultural production.
Rice is China's staple food crop, and the snout moth's larva of rice and plant hopper are the primary pests in Rice Cropping, wherein and with
Rice leaf roller, striped rice borer and brown paddy plant hopper, white backed planthopper harm is very.
Striped rice borer Chilo suppressalis (Walker) is that Occurrence the most serious is endangered on China's rice
One of, tillering stage it is aggrieved cause withered sheath, withered heart seedling, cause insect bite strain and dead ears ear period is aggrieved, the general time underproduction 8%~
10%, the underproduction is more than 3 one-tenth when serious.Domestic each rice region is distributed, wide compared with yellow rice borer and pink rice borer distribution, but mainly with the Changjiang river
Basin and on the south rice region occur heavier, it is in the situation that obviously rises that quantity occurs in recent years.Striped rice borer is in addition to hazard rice, moreover it is possible to
Endanger the weeds such as the crops such as wild rice stem, corn, sorghum, sugarcane, rape, semen viciae fabae, wheat and reed, barnyard grass, Leersia Sw.
Striped rice borer is not only the important pests in China's Rice Production, and in external paddy fields, distribution is also very wide, for example,
The harm of the country such as Korea, Japan, Philippine, Vietnam, Thailand, Malaya, Indonesia, India striped rice borer is also very tight
Weight.
Rice hoppers (rice planthopper) belong to Homoptera Delphacidae.Hazard rice mainly has brown paddy plant hopper, white
Backward flight lice and three kinds of small brown rice planthopper.Endangering heavier is brown paddy plant hopper and white backed planthopper, early rice early period based on white backed planthopper, the later period with
Based on brown paddy plant hopper；Middle late rice is based on brown paddy plant hopper.
Planthopper causes harm to rice, removes direct piercing and sucking juice, makes growth retardation, and rice clump is agglomerating withered when serious, even
The complete dead stalk lodging in field is outer, and oviposition can also stab plant, destroy conducting tissue, interfere nutriment transport and transmitted virus disease.
Currently, prevention and treatment the snout moth's larva of rice and plant hopper compounded pesticides kind it is more, mainly have to planthopper control efficiency compared with
Good imidacloprid with to the preferable Cupric sulfate of snout moth's larva control efficiency, Hostathion, phoxim, chlopyrifos, avermectin, Bassa etc.
