Abstract

The invention designs a weeding composition containing monosulfuron-ester and halosulfuron-methyl. The weeding composition containing the monosulfuron-ester and the halosulfuron-methyl is optimally composed of the monosulfuron-ester and the halosulfuron-methyl as two active ingredients, as well as a vector and an auxiliary, wherein weight ratio of the monosulfuron-ester to the halosulfuron-methylis (1 to 80) to (80 to 1). The weeding composition is capable of producing relatively good synergistic effects so as to inhibit and delay resistance production of weeds, as well as enlarging prevention and treatment spectrum; moreover, the weeding composition is long in effective time, so that medication cost is reduced. The weeding composition containing the monosulfuron-ester and the halosulfuron-methyl can be used for preventing and treating weeds in wheat fields.

Description

technical field [0001] The invention relates to the field of pesticide herbicide and relates to a herbicide composition containing monosulfuronate and chlorpyrazosulfuron-methyl. Background technique [0002] Monosulfuron ester (monosulfuron ester) is another super-efficient herbicide developed by Nankai University following the industrialization of monosulfuron-methyl. Monosulfuronate can be used in winter and spring wheat to prevent and control weeds such as quinoa, succulents, mustard, and wormwood in the field, and the effective dosage is only 1-1.5 grams per mu. As an ultra-high-efficiency creative pesticide with independent intellectual property rights in my country, the research results show that monosulfuronate has a good control effect on weeds in wheat fields at a dose of 1.5 g / mu, and has a good control effect on weeds in wheat fields. Very safe, this feature is obviously superior to other sulfonylurea compound herbicides. But a single agent is not sensitive to s...
