High-efficiency and low-toxicity composite bird repellent containing thiram and dimethyl phthalate

Abstract

The invention provides a high-efficiency and low-toxicity composite bird repellent containing thiram and dimethyl phthalate. The composite bird repellent contains active components of thiram and dimethyl phthalate, wherein the mass ratio of the thiram to the dimethyl phthalate is (4: 1)-(1: 20). The composite bird repellent has a very good bird repelling effect; and the thiram and the dimethyl phthalate have an obvious synergistic effect, have no direct bird killing capability and have low toxicity to humans and other mammals, so that the composite bird repellent is long in lasting effect and safe to crops, and can effectively reduce damage of birds to field crops, orchards and the like.

Description

technical field [0001] The invention belongs to the field of agricultural chemical bird repellent, and specifically relates to a high-efficiency, low-toxic compound bird repellant containing thiram and dimethyl phthalate, which is mainly used for repelling seeds during sowing, crop maturity, orchards, etc. Bird damage in the field. Background technique [0002] In recent years, the state has gradually increased its efforts to protect bird resources, and most birds have become key protected animals. But as bird populations continue to increase, the birds are causing more and more problems in areas such as crop production. Birds have begun to attack more and more crops. Not only citrus, loquat, grapes, rice, peanuts and other crops are not spared, but even bagged fruits are also endangered by long-billed birds such as gray magpies and crows. When the crops are just sown, the birds will plan and eat the seeds, which will harm the sowing of the crops and cause uneven emergence...

AI Technical Summary

Problems solved by technology

Thiram is used to repel birds, and it has been recorded in the literature. However, when used alone, the effect of repelling birds in common doses is very poor. Although it has improved at high doses, it is still not ideal, and it is not economical when used in large quantities, and it is not conducive to environmental protection.

The use of dimethyl phthalate in agriculture for bird removal has not been reported in the literature. According to the experiment of the inventor, a very high dose of dimethyl phthalate (0.4% higher than the seed mass) is less than 50% % bird repellent activity, and this dose has a certain effect on emergence
