Description

Nitenpyram and indoxacarb Recompounded pesticide
Technical field
The invention belongs to technical field of compounded pesticide, be specially Nitenpyram and indoxacarb Recompounded pesticide.
Background technology
Paddy rice is the principal item in China cereal crops, and cultivated area is large, and disease, worm, crop smothering kind are many, and harm is heavy.According to agricultural sector statistics, every year due to illness, the harm such as worm, grass, production loss reaches 20~30%.The agricultural chemicals quantity that disease, worm, crop smothering on the control paddy rice uses accounts for 50% left and right of China's agricultural chemicals year usage amount.Area is controlled to the medicine of rice grub in the whole nation, and throughout the year 1,200,000,000 mu of left and right, insect outbreak year medicine is controlled area can be larger.
The pesticide species of control Insect Pests in Rice as the control rice leaf roller, for many years, uses the desinsection list, and chlopyrifos is more, nearly 3~5 years, uses the medicaments such as Avermectin, Affirm (Merck Co.) hydrochloride.Large area control to rice leaf roller has reached good effect, but develop immunity to drugs afterwards for many years owing to using, control efficiency descends year by year, in recent years introduce the medicaments such as indoxacarb that du pont company produces, Rynaxypyr, lepidoptera pest on the control paddy rice, dosage is few, and preventive effect is good, but pesticide price is high, and spread uses also certain difficulty.And for example prevent and treat the rice fulgorid class pest, since the nineties in last century, used Buprofezin (claiming again buprofezin), the agricultural chemicals such as Imidacloprid are got the control of national rice fulgorid and have been gone larger achievement.But since this century, the agricultural chemicals such as Imidacloprid have produced stronger pesticide resistance to brown planthopper, and control efficiency descends.So that the medicament exploitation of control rice fulgorid becomes the task of top priority.
In China paddy rice producing region, especially the rice district's paddy growth middle and later periods on the south the Yangtze river basin, lepidoptera pest such as snout moth's larva, rice leaf roller and homoptera pest such as rice fulgorid class are mixed often sends out.Especially rice leaf roller and brown planthopper become the primary pest of paddy rice middle and later periods.When selecting pesticide species, consider the double former medicine kind of controlling effect, can receive that just preventive effect is good, reach again saving of labor, economical purpose.For this reason, some obligate insecticides are carried out composite, enlarging insecticidal spectrum just has this purpose.
Summary of the invention
For the above-mentioned problems in the prior art, the object of the invention is to design provides the wider Nitenpyram of a kind of low toxicity, insecticidal spectrum and the technical scheme of indoxacarb Recompounded pesticide, its quick-acting and lasting effect are good, and paddy rice lepidoptera pest and homoptera pest are had better control efficiency.
Described Nitenpyram and indoxacarb Recompounded pesticide is characterized in that containing the following material of weight percentage: Nitenpyram 1.5~2.5%, indoxacarb 1.5~2.5%.
Described Nitenpyram and indoxacarb Recompounded pesticide is characterized in that: Nitenpyram content is 1.6~2.2%, and indoxacarb content is 1.6~2.2%.
Described Nitenpyram and indoxacarb Recompounded pesticide is characterized in that: Nitenpyram content is 1.8~2.0%, and indoxacarb content is 1.8~2.0%.
Nitenpyram (Nitenpyram) is anabasine insecticide, and low toxicity, good water solubility, desinsection principle are mainly that insect cynapse acceptor is had the nerve block effect.To homoptera pest such as rice fulgorid have efficiently, low toxicity, interior suction and without advantages such as cross resistances.
Indoxacarb, English common name (Indoxacarb) has another name called safety hit, An Guan, Ammate, Vatar.To the little poison of higher mammal, fool proof to people, animal, fool proof to birds and aquatile.The insecticidal mechanism of indoxacarb is the sodium channel inhibitor, and the main sodium channel of passing through in blocking-up insect nerve cell makes the coordination of target pest impaired, numb fraud occurs, and is finally lethal.
Described Nitenpyram and indoxacarb Recompounded pesticide according to its purposes, can be processed multiple formulation, as aqueous emulsion, add solvent, emulsifier to make by former medicine; Also can make water dispersant, add bleeding agent, diffusant, wetting agent, binding agent, filler etc. to make by former medicine.The production technology that specifically is mixed and usual auxiliaries all belong to existing known technology, do not repeat them here.
Above-mentioned Nitenpyram and indoxacarb Recompounded pesticide, greater than 120, both are composite has obvious synergistic effect, and the homoptera pests such as Brown Planthopper and lepidoptera pest are had better control efficiency to the co-toxicity coefficient of Brown Planthopper.This Recompounded pesticide low toxicity, insecticidal spectrum are wider, and quick-acting and lasting effect are good, and production cost is low.
Proportioning in present patent application is the weight percentage of the pure material of active ingredient.

Test two. the field control effectiveness test of above-mentioned Recompounded pesticide to Brown Planthopper.Be the reliability of checking proportioning screening, heading stage carried out 4% Nitenpyram indoxacarb mixed agent (formula 3) field trial at hybrid rice (excellent No. one of middle Zhejiang) in by the end of August, 2010-September.
1. field reagent kind and consumption:
(1) 4% Nitenpyram indoxacarb mixed agent (formula 3) mu consumption 100 grams;
(2) 3% indoxacarb aqueous emulsion mu consumption 80 grams;
(3) 5% Nitenpyram aqua mu consumption 50 grams;
(4) blank.
2. method: adopt deployment residential quarter, triplicate.Before medication, 7 days, 11 days employing dish bat methods after medicine are investigated hundred clumps of worm amounts of brown planthopper adult, nymph and the spider of each residential quarter.Calculate after medicine the brown planthopper insect population decline rate, control efficiency of 7 days, 11 days and to the fragmentation effect of spider.
3. result of the test sees Table 9.
Figure 606788DEST_PATH_IMAGE001
Result of the test shows: 4% Nitenpyram indoxacarb mixed agent (formula 3) mu is used 100 grams, and after medicine, the insect population decline rate of 7 days, 11 days brown planthoppers is respectively 75.7% and 82.1%, and control efficiency is respectively 81.1% and 86.1%.Compare with the contrast medicament, higher than indoxacarb, slightly lower than the control efficiency of mu with the Nitenpyram of 50 grams.Carry out the field control effectiveness test of Brown Planthopper with formula 1-2 and formula 4-5, also can reach the test effect similar to formula 3.
