Abstract
The present invention discloses a compound insecticide of fipronil, which belongs to the technical field of compound insecticides. The compound insecticide of fipronil is characterized in that the compound insecticide comprises 0.2 to 6 percent of fipronil and 10 to 40 percent of profenofos. The cotoxicity coefficient of the compound insecticide of fipronil reaches 639 to 897, and the effect of controlling pests, such as striped rice borers, prodenia lituras, etc., is good; experiments indicate that the controlling rate of the striped rice borers reaches 97.3 percent, and the death rate of the prodenia lituras reaches 94.7 percent; the quick effect and the durable effect are good, the harm to the environment and human bodies is small, and the cost is low and is reduced about 30 to 50 percent than the cost of fipronil insecticide.
Description
Technical field
The invention belongs to technical field of compounded pesticide.
Background technology
Fluorine worm nitrile agricultural chemicals used on China paddy rice and obtains interim registration (5% colloidal suspending agent) in 1994, and 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 goitre line, 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, and therefore, in the paddy rice producing region of using fluorine worm nitrile 3-4, the population ratio of pink rice borer rises very fast.Higher to the toxicity of fishes and shrimps in addition, in the network of rivers, the lake region uses and also can be subjected to certain restriction.Simultaneously, the quick-acting of fluorine worm nitrile agricultural chemicals is poor slightly, agricultural chemicals price higher (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, and can play better effect in the rice disease and pest integrated control.If adopt China that certain production scale, low toxicity (comprising fish, honeybee) are arranged at present, the lower-cost agricultural chemicals of now using, as pesticide species such as Profenofos, carry out reasonably composite with it, test through series of selection, the tangible composition of selective advance strengthens quick-acting, and reducing pesticide cost is the key point of Firponil compounded pesticide.
Summary of the invention
Based on the problems referred to above, the technical scheme of the Firponil compounded pesticide that insects such as the object of the invention is to provide a kind of poisoning, cost is low, insecticidal spectrum is wide, control striped rice borer, Noctuidae are effective.
Described a kind of Firponil compounded pesticide is characterized in that: contain fluorine worm nitrile 0.2-6%, Profenofos 10-40%.
Described a kind of Firponil compounded pesticide is characterized in that: the content of fluorine worm nitrile is 0.2-4%, and the content of Profenofos is 10-35%.
Described a kind of Firponil compounded pesticide is characterized in that: the content of fluorine worm nitrile is 0.2-2.5%, and the content of Profenofos is 20-30%.

The 30% fluorine worm nitrile Profenofos Recompounded pesticide of analyzing said ratio is to striped rice borer co-toxicity coefficient determination test data, and measurement result shows that the co-toxicity coefficient of fluorine worm nitrile and Profenofos different proportion prescription all has the notable synergistic effect greater than 100.With 30% fluorine third (prescription three) co-toxicity coefficient maximum, consider that wherein 30% fluorine third (prescription two, prescription three) can be used as prioritization scheme and selects from pesticide cost and drug effect.
Control efficiency result of the test from above-mentioned field to striped rice borer can be found out: composite dose of 30% fluorine worm nitrile Profenofos (prescription three), and every mu of dosage 100g, withered heart rate only are 0.23%, control efficiency is 97.3%; 5% fluorine worm nitrile mu restrains with 40, and withered heart rate is 0.28%, and control efficiency is 96.7%; 40% Profenofos mu restrains with 100, and withered heart rate is 3.5%, and control efficiency is 58.3%.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, composite dose of control efficiency to striped rice borer of 30% fluorine worm nitrile Profenofos is best.
Simultaneously, measure from the above-mentioned lethality that Noctuidae prodenia litura 3 instar larvaes are done: composite dose 1000 times, 2000 times, 3000 times liquid of 30% fluorine worm nitrile Profenofos, the lethality of Spodoptera litura larvae is respectively 95.0%, 94.7% and 77.8%; 1000 times, 2000 times, 3000 times liquid of 5% fluorine worm nitrile suspending agent, the lethality of Spodoptera litura larvae is respectively 50%, 25% and 0%; 1000 times, 2000 times, 3000 times liquid of 40% Profenofos missible oil, the lethality of Spodoptera litura larvae is respectively 95.2%, 57.9% and 37.5%; The result shows, composite dose of 30% fluorine worm nitrile Profenofos has the better prevention effect to noctuidae pests.
Composite dose of 30% fluorine worm nitrile Profenofos, in every mu of medication 60-80 gram, pesticide cost is about 3-4 unit; And single with 5% fluorine worm nitrile suspending agent, in mu medication 40 grams, pesticide cost is about 6 yuan.As seen, the cost of composite dose of 30% fluorine worm nitrile Profenofos is than 5% fluorine worm nitrile decline 30%-50%.
