Abstract
Fipronil and fenobucarb composite pesticide characterized in that its constituents include Fipronil 0.2-10%, Fenobucarb 10-40%, the pesticide can be made into the forms of missible oil by charging organic solvent and emulsifying agent into raw medicine, or made into aqueous emulsion by charging organic solvent, auxiliary solvent, wetting agent, dispersing agent, anti-freeze agent, emulsifying agent and water into crude pesticide. The pesticide can be used for controlling rice pests and locusts, especially for controlling Chilo supperssalis and rice case worm.
Description
Technical field
The invention belongs to technical field of compounded pesticide, be specially fluorine worm nitrile and fenobucarb composite pesticide.
Background technology
Fluorine worm nitrile obtained interim registration (5% suspending agent) in 1994 on China paddy rice, registration number is LS94007.Be widely used in the control of rice grub and migratory locusts in recent years,, good control efficiency arranged as insects such as rice gall midge, rice thrips, striped rice borer, rice fulgorid, oryza chinensis to rice grub.But the control efficiency to paddy stem borer, rice leaf roller is undesirable, and is bad to the pink rice borer control efficiency that takes place on the paddy rice, therefore, using the paddy rice producing region in 3～4 years of fluorine worm nitrile, and the population ratio of pink rice borer rises very fast.In addition to the toxicity height of fishes and shrimps, in the network of rivers, the lake region uses and also can be subjected to certain restriction.The quick-acting of fluorine worm nitrile agricultural chemicals is poor slightly simultaneously, agricultural chemicals price height (6～7 yuan every mu), and this also is to limit this medicine in one of widely used factor of China.
Fluorine worm nitrile is this to have a moderate toxicity in order to make, and insecticidal spectrum is wide and can adapt to China rice grub to the agricultural chemicals of advantages such as pest controling effects such as striped rice borer are good and prevent and treat market, can play better effect in the rice disease and pest integrated control.If adopt China that certain production scale, low toxicity (comprising fish, honeybee), the lower-cost agricultural chemicals of now using are arranged at present, carry out reasonably composite with it, test through series of selection, the tangible composition of selective advance, as pesticide species such as Bassas, strengthening quick-acting, enlarging insecticidal spectrum, reduce pesticide cost is the key point of Firponil compounded pesticide.
Summary of the invention
The object of the invention is to solve the above-mentioned problems in the prior art, and design provides a kind of fluorine worm nitrile of low toxicity and the technical scheme of fenobucarb composite pesticide, and its insecticidal spectrum is wide, and quick-acting good with lasting effect, cost is lower.

In order to screen fluorine worm nitrile and different composite dose of control efficiency thereof to rice leaf roller, select paddy rice institute base double cropping late rice (kind is No. 11, elegant water) field, make the field small plot experiment.Paddy rice is in jointing-booting stage.The rice leaf roller adult mostly is and falls groove August 14 (Yun Na) and move into, and it is more neat that larvae development is gone through the phase.The sub-district area is 30m
2, every chemicals treatment triplicate.Because leaf roll rate occurrence degree is inconsistent before each sub-district medicine, therefore, blank is provided with five repetitions, in the hope of representing the insect pest situation abiogenesis degree of Quan Tian.Test in dispenser on September 3, rice leaf roller larvae is the 2-3 length of time, because the leaf roll of existing some before the medicine, therefore, respectively investigated the leaf roll rate once in 7 days before medicine and behind the medicine, calculate the leaf roll growth rate, each is handled and the relative control efficiency of the clean Growth Rate Calculation of the leaf roll of blank, observe each medicament simultaneously and have or not poisoning to take place paddy rice.
The secondary multiple ingredients of 30% fluorine, 5% fluorine worm nitrile suspending agent, 40% Bassa missible oil, 40% chlorpyrifos ec, the field control effectiveness test of blank control rice leaf roller, its test data is as follows:
The field test effect table of 30% fluorine worm nitrile fenobucarb composite agent control rice leaf roller
| Handle | The mu dosage | Average leaf roll rate before the medicine | 7 days average leaf roll rates behind the medicine | Leaf roll rate net added value | The leaf roll growth rate | Relative control efficiency |
| (gram) | (％) | (％) | (％) | (％) | ||
| The secondary multiple ingredients of 30% fluorine | 100 | 11.3 | 12.6 | 1.3 | 11.5 | 88.5 |

Measurement result shows that the co-toxicity coefficient of prescription one is 739; The co-toxicity coefficient of prescription two is 786; The co-toxicity coefficient of prescription three is 606; The co-toxicity coefficient of prescription four is 564; The co-toxicity coefficient of prescription five is 614, all greater than 100, has obvious synergistic effect.Each proportioning synergy is obvious, consider from the lasting effect of reagent cost and medicament, with fill a prescription two and prescription three as preferably.
Control efficiency result of the test through the field to striped rice borer shows: 30% fluorine worm nitrile fenobucarb composite agent (0.9+29.1% proportioning) mu medication, 100 gram control striped rice borer, checked that withered heart rate only was 0.23% in 20 days behind the medicine, and control efficiency is 97.3%; The withered heart rate of 5% fluorine worm nitrile is 0.28%, and control efficiency is 96.7%; The withered heart rate of 40% Bassa missible oil is 2.43%, and control efficiency is 71.0%.Domestic 20% triazophos emulsifiable solution mu medication, 100 grams commonly used at present, withered heart rate reaches 3.1%, and control efficiency only is 63.1%.As seen, the composite dose of control efficiency to striped rice borer of fluorine worm nitrile and Bassa is best.The above-mentioned medicament of respectively handling does not have bad reaction to rice growth, the treatment region of fluorine worm nitrile fenobucarb composite agent, and the rice is doing well, and the leaf look delicate and pretty, and the later stage heading is neat.
In the field rice leaf roller is prevented and treated test, the result is as follows: 30% fluorine worm nitrile Bassa (0.9+29.1% proportioning) Recompounded pesticide mu restrains with 100, and the leaf roll net added value is 1.3, and control efficiency is 88.5%; 5% fluorine worm nitrile suspending agent mu restrains with 30, and the leaf roll net added value is 3.2, and control efficiency is 71.7%; 40% Bassa missible oil mu restrains with 100, and the leaf roll net added value is 7.5, and control efficiency is 33.6%.Best agricultural chemicals-the chlopyrifos of domestic present control rice leaf roller, mu restrains with 100, and the leaf roll net added value is 0.7, and control efficiency is 93.8%.As seen, the agent of fluorine worm nitrile fenobucarb composite also has the better prevention effect to rice leaf roller.Above-mentioned each medicament has no adverse reaction to rice growth.
Single with 5% fluorine worm nitrile suspending agent mu medication, 40 grams, pesticide cost is 6.0 yuan.If with 30% fluorine worm nitrile fenobucarb composite agent, in mu medication 80 grams, pesticide cost is about 2.4 yuan, descends 55～65% than single mu with fluorine worm nitrile with cost.
