Description
Technical field
The present invention relates to technical field of pesticide, particularly a kind of preparing technical field of preventing and treating the pesticidal preparations of rice hoppers and other rice pests.
Background technology
Paddy rice is the important cereal crops that depend on for existence of 35% people in the world, and the height of its output is concerning social stability.But paddy rice usually suffers the invasion and attack of various damage by disease and insect, particularly insect pest in the whole growth growth course, and wherein snout moth's larva, rice leaf roller and rice fulgorid are the three big primary pests of paddy rice of causing harm.Because it is dim that global climate becomes, insect worm attitude changes, and in recent years, insect large tracts of land such as the snout moth's larva of rice, rice fulgorid are broken out, serious threat the sustainability production of paddy rice.Rice grub is more and more rampant, and general insecticide can not reach desirable control efficiency, and the higher agricultural chemicals of some toxicity though can play certain preventive and therapeutic effect, has very big harm equally to people and environment.Along with the raising of people's living standard, people to the requirement of rice by scalar type to the conversion of high-quality type, the development pollution-free rice trend that is inevitable.
The nimbin botanical pesticide is exactly one of them typical case's representative.Neem extract has significant effect to the common insect in most of rice fields, reports that wherein more is the rice fulgorid and the snout moth's larva of rice etc.Dash etc. utilize 5%NSKE and 1%Repelin spraying to handle white-backed planthopper and brown planthopper, and the result shows that two kinds of preparations have the better controlled effect to plant hopper.The Dash key evaluation effect of common in the market seal chinaberry preparation to the rice field primary pest; Find that nearly all reagent agent all has remarkable result to brown planthopper and white-backed planthopper, paddy stem borer is also had medium control action, in these medicaments, Rakshak and Nimbecidin drug effect are best.Employing honeydew method of draining such as Krishnaiah have been studied NG4, RakshaK, the Neem Azal T/S food refusal effect to brown planthopper, white-backed planthopper and nephotettix bipunctatus, and all are handled all positive effect.In 2%NG4,1.0%Rakshak, 1.0%Neem Azal T/S handled, the food refusal rate reached 82.91%, 86.76%, 84.76% respectively.Dhaliwal etc. have estimated the field effect of Rakshak, Neem, Azal T/S, Nimbecidine control rice leaf roller and paddy stem borer.The rice leaf roller of 5%Neem Azal T/S treatment region and the paddy stem borer rate that causes harm significantly reduces.Utilize seal chinaberry preparation can also effectively control the rice root insect.
Chakroborti has estimated the effect to paddy stem borer, paddy rice armor and rice case bearers of neem oil, neem cake, seal chinaberry kind nuclear extract and chemical pure nimbin, finds that neem extract has the effect suitable with chemical pesticide to 3 kinds of insects.
Nimbin (azadirachtin) is the outstanding biopesticide of generally acknowledging, active component derives from the seal chinaberry.The main insecticidal action mode of nimbin is food refusal, suppress to grow, stomach toxicity, avoid and keep away, suppress to breathe and various active such as sterile, wherein with suppress to grow, food refusal and deterrent effect be particularly remarkable.At present, seal chinaberry preparation is widely used in preventing and treating insect on cotton, vegetables, fruit tree, tea tree, paddy rice and the pea.Seal chinaberry insecticide has almost reached all requirements of present pesticide developing: wide spectrum, and efficient, selectivity is good, and to non-target organism safety, to people and animals' low toxicity, noresidue is degraded rapidly in no poisoning in environment.
Rynaxypyr (chlorantraniliprole) is the O-formammidotiazol-benzamide broad spectrum pesticide, mainly prevents and treats the lepidoptera pest of various crop, and other insects are also had preventive effect preferably; The mode of action is stomach toxicity and contact toxicity, and wherein stomach toxicity is the main mode of action.Its mechanism of action is to activate blue Buddhist nun's alkali acceptor, discharges the calcium of storing in smooth muscle and the striated muscle cell, causes that the muscle adjusting is weak, the fiber crops illness, until insect death.Rynaxypyr can also can move by the root absorption with at xylem in stem, leaf surface infiltration plant corpus.
Rynaxypyr is because its unique chemical structure and the brand-new mode of action, have safely, dispenser personnel, poultry, domestic animal are not all had harm, to insect natural enemy and also not influence of environment, simultaneously again target pest (rice leaf roller, striped rice borer etc.) is had special efficacy, and the lasting period is long.As Rynaxypyr 200g/L suspending agent the paddy rice rice leaf roller there are higher activity and control efficiency.
But the unitary agent of above nimbin preparation and Rynaxypyr has run into serial problem in actual use.Exist production cost higher as the nimbin preparation in use in the field, nimbin makes drug effect, the lasting effect of nimbin be subjected to influence because photodissociation, hydrolysis etc. easily take place in natural environment in addition, and the control efficiency of insect has been subjected to certain influence.Rynaxypyr has the better prevention effect to rice grub at present as a kind of chemical pesticide of new listing, but in order to improve the control efficiency of medicament to insect, the peasant constantly improves the using dosage of medicament, and insect easily produces resistance to medicament in addition.
