Problems solved by technology

The combined infection of H.filipjevi and H.avenae in the Huanghuai wheat region and the main wheat producing areas in Henan not only aggravated the yield loss of wheat, but also brought new opportunities for the promotion of disease-resistant varieties and the control of wheat cyst nematodes. Great challenge to wheat production, while the threat to wheat production is even more serious

Abstract

The invention, which belongs to the field of pest control, particularly relates to a compound medicament for preventing cereal cyst nematode and aphid of wheat. The effective components of the compound medicament comprise imidacloprid and fluopyram in a mass ratio of 3: (0.4-6.7). According to the invention, the proportion of effective components in the compound medicament is improved, and finally, imidacloprid and fluopyram in a certain proportion are selected to be compounded as the effective components. Indoor sterile soil cultivation tests and field tests prove that the compound medicamentis free of phytotoxicity, high in budding rate and good in cyst nematode prevention and control effect; meanwhile, the compound medicament has a good inhibition rate and prevention and control effecton aphids.

Description

technical field [0001] The invention belongs to the field of insect pest control, and in particular relates to a compound agent for preventing wheat sporogenes and aphids. Background technique [0002] Wheat cereal cyst nematode (Heterodera avenae) is a worldwide important pathogenic nematode that harms wheat, barley, oats, rye and a variety of grass crops. It has been reported in more than 40 countries around the world. Production poses a serious threat. The control measures of wheat cereal cyst nematode mainly include: land fallow and non-host crop rotation, selection and utilization of disease-resistant varieties, chemical control, biological control, etc. The use of non-host plant rotation methods can reduce the nematode population density in the field to a certain extent, but the host range of cereal crop cyst nematodes is wide, it is difficult to eradicate, and the economic loss is large, which is not suitable for my country's agricultural planting mode and national c...
