Description

Efficient pesticides

The present invention relates to a kind of insecticide, be specially adapted to prevent and treat the lepidoptera pest on the snout moth's larva of rice and fruit tree, cotton, the tealeaves.

Snout moth's larva is to endanger one of the most serious insect pest in China's south rice production.In recent years, because the change of cropping system, as bridging host's single cropping rice cultivated area expansion, thereby the harm of snout moth's larva more became seriously, and snout moth's larva all has distribution in China southern and northern rice district.Endanger light paddy rice loss and can reach 1-2, serious reaches 4-5.At present, the medicament of control snout moth's larva mainly contains agricultural chemicals such as dimehypo, desinsection list, Hostathion, parathion-methyl, acephatemet.The toxicity height that these medicaments have, preventive effect is still undesirable; What have uses through for many years, and insect develops immunity to drugs.To 1997, many experts cry out in alarm, and snout moth's larva is near the situation that pasts medical help.The application's efficient pesticides is that Olivomitecidin and Triazoxide as built-up form, and it is wide to have an insecticidal spectrum, and the insecticide efficiency height is to characteristics such as the person poultry toxicity are low.Snout moth's larva is prevented and treated efficient to be reached more than 95%.

The present invention's purpose is to provide a kind of composition ratio difference, but can effectively prevent and treat the insecticide of other lepidoptera pests such as the snout moth's larva of rice.

The present invention is to be Main Ingredients and Appearance with Hostathion, Olivomitecidin, and interior solubilizer and an amount of " high osmotic agent ", " synergist " process.The part by weight of its main composition Hostathion, Olivomitecidin is: 0.2-40: 0.0001-0.8.

The insecticide that makes by above-mentioned prescription compared with prior art, manufacturing conditions requires low, permeability is strong, good disinsection effect, it not only has good preventive effect to the low age insect, and high instar larvae is also had very strong lethal effect; Secondly, the ability of the anti-rain drop erosion of insecticide of this invention is stronger, and general dispenser is just rained after 2 hours effectively.According to the test on crops such as paddy rice, cotton, fruit tree, to the preventive effect of snout moth's larva and other lepidoptera pest all more than 95%.
