Abstract
A pesticide in the form of seed coating agent, suspension, powder, or emulsifiable concentrate for the pests (rice stem maggot) is prepared from fipronil and imidacloprid in wt. ratio of (0.1-1):(0.1-1). Its advantages are high effect (87.5%), no damage to human body, livestock, fish and useful insects, and no environmental pollution.
Description
The present invention relates to a kind of insecticide of preventing and treating insect pests such as paddy rice, a kind of insecticide that is mainly used to kill rice stem maggot of definitely saying so.
Paddy rice is the staple food crop of China, and cultivated area accounts for 30% of cereal crops, and output accounts for 40% of total grain output.Rice Production plays crucial effects to the development of the national economy and the stable living standards of urban and rural residents.Rice pest is the important biomolecule disaster that influences the rice high yield stable yields, according to domestic and international expert determination, rice growing season throughout the year due to illness the production loss that causes of insect pest be about 10-15%.At home, both the central and local governments, governments at all levels all pay much attention to the harmful volume increase of paddy rice control, and the expense that is used for the extermination of disease and insect pest every year all reaches more than several hundred million units.
Rice stem maggot is the sporadic rice grub in some areas at home of a kind of past, never paddy rice is caused heavy losses.But since the mid-90, the most of at home rice of rice stem maggot district breaks out causes disaster, and the damaging range rapid spread enlarges in a short time, nearly 100,000,000 mu of area.This worm hides always and endanger the tender growing point of children in rice plant after rice seedling is invaded, and after the plant children fringe first half of being injured was eaten, the degeneration of grain husk flower can not form normal grain.Showing as the tassel first half after the heading does not have grain, only has a little degeneration to turn white and props up stalk or the little clever shell of deformity, and grouting back tassel is the not killed shape of eave tile.Because the final directly hazard rice fringe front portion of rice stem maggot, the production loss that causes is very big.According to investigations, the general lost units 10-20% in the field that is injured, the loss of heavily harmful field surpasses 30%.
For just breaking out the rice stem maggot that causes disaster in recent years, domesticly do not work out ripe supporting Prevention Technique as yet, great majority are injured the district peasant in the face of serious harm loss, still feel simply helpless so far.According to the test of domestic many research and production department, at present in the domestic and international existing insecticide, except that the highly toxic pesticide furans pellet of forbidding has the control efficiency of 70-80%, other medicament is to the rice stem maggot nearly unavailable.
The objective of the invention is to: provide a kind of special-purpose control rice stem maggot, the double high-efficient low toxicity insecticide of controlling other rice grub.
The objective of the invention is that following technical scheme realizes by implementing:
The insecticide of control rice stem maggot, by fluorine worm nitrile and two kinds of medicament mixed preparing of Imidacloprid, its formulation weight ratio is a fluorine worm nitrile: Imidacloprid=1: 0.1～0.1: 1; Fluorine worm nitrile, chemical name: (±)-5-amino-1-(2,6-two chloro-α, α, α-three fluoro-p-tolyl-)-4-trifluoromethyl one sulfinyl pyrazoles-3-carbonization nitrile), its molecular formula: C
12H
4CL

4OS; Imidacloprid, chemical name: 1-(6-chloro-3 picolyls)-N-nitro rice azoles-2-enamine), its molecular formula: C
9H
10CLN
5O
2These two kinds of medicaments are made this insecticide raw material and all can be buied by market.
Utilize said components and proportional quantity can make kind of a clothing agent, seed dressing, suspending agent, pulvis, the insecticide of multiple different dosage form such as missible oil.
The invention has the advantages that: to rice stem maggot desinsection drug effect height, generation that can the effectively preventing insect pest with spread.In the heavily harmful district of rice stem maggots such as Sichuan Province's Mianzhu, the field trial demonstration result that carries out shows: the different dosage form such as the agent of kind clothing, seed dressing, suspending agent that utilizes medicament of the present invention, the average effect of control rice stem maggot is 87.5%, the control efficiency that is higher than highly toxic pesticide furans pellet, the medicament application area is retrieved paddy loss 25-50 kilogram for every mu, every mu increases income 20-40 unit, and the input and output ratio is 1: 4～8, and economic benefit is fairly obvious.
Second advantage of the present invention is: the toxicity of this medicine is very low, and the medicament of making various formulations all compares safety to aquatiles such as useful insect such as people and animals, paddy field spider and fish.In the paddy field, after the dispenser, can not produce as using highly toxic pesticide furans pellet environment such as rice field, water source are produced severe contamination, cause directly problem such as poisoning and chronic murder by poisoning of people and animals.
The toxicity test report is mended with test of pesticide effectiveness report back.
