Abstract
The present invention discloses a fipronil compound pesticide which belongs to the technical field of the compound pesticide. The fipronil compound pesticide is characterized in that the fipronil compound pesticide comprises 0.2 to 10 percent of fipronil and 10 to 50 percent of malathion. The cotoxicity coefficient of the fipronil compound pesticide to striped rice borers reaches 230 to 536, the effect on controlling pests, such as the striped rice borers, rice leaf rollers, etc., is good, the controlling rate for the striped rice borers reaches 98.7 percent, the controlling rate for the rice leaf rollers reaches 89.4 percent, the quick effect and the durable effect are good, the harm to environment and human bodies is small, the cost is low, and compared with the cost for solely using fipronil pesticides, the present invention reduces the cost about 25 percent.
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 malathions, 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, rice leaf roller are effective.

The 25% fluorine worm nitrile malathion 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 malathion different proportion prescription all has the notable synergistic effect all greater than 100.With 25% fluorine horse (prescription two) co-toxicity coefficient maximum, consider that wherein 25% fluorine horse (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 25% fluorine worm nitrile malathion (prescription three), and every mu of dosage 100g checked that withered heart rate only was 0.11% in 20 days behind the medicine, control efficiency is 98.7%; 5% fluorine worm nitrile mu restrains with 40, and withered heart rate is 0.28%, and control efficiency is 96.7%; 45% malathion mu restrains with 100, and withered heart rate is 2.43%, and control efficiency is 71.0%.Use current common pesticides, 20% triazophos emulsifiable solution mu medication, 100 grams, 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 in 25% fluorine worm nitrile malathion is best.
Simultaneously, find out from above-mentioned field control effect test data to rice leaf roller: composite dose of 25% fluorine worm nitrile malathion (prescription three), checked that control efficiency reached 89.4% in 7 days behind the medicine; 5% fluorine worm nitrile mu is that 71.7%, 45% malathion mu restrains with 100 with 30 grams, control efficiency, and control efficiency is 29.2%; The result shows, there is the better prevention effect composite dose of 25% fluorine worm nitrile malathion to rice leaf roller.
Composite dose of 25% fluorine worm nitrile malathion, producer price per ton is about about 4.0 ten thousand yuan, reduces cost about 25% than single with fluorine worm nitrile.
