Embodiment 1

[0063] Embodiment 1 co-toxicity coefficient measurement:

[0064] In order to better understand the joint action and effect of the herbicide composition of the present invention on weeds, it is detected by the following method, specifically as follows:

[0065] Adopt co-toxicity coefficient method to evaluate the synergistic effect of herbicide composition provided by the invention and pharmaceutical preparation thereof: with the growth inhibition percentage or the fresh weight inhibition percentage (Y) of the natural logarithm of drug concentration (X) and drug to target weeds ) to find the regression equation, and calculate the EC50 value or EC90 value of the agent on weeds, and then find the co-toxicity coefficient. The co-toxicity coefficient was used to evaluate the joint effect of compound agents on weeds. The co-toxicity coefficient > 120 was indicated as synergistic effect, the co-toxicity coefficient between 80 and 120 was expressed as additive effect, and the co-toxi...

Abstract

The invention relates to the technical field of herbicides, and in particular relates to a weeding composition and a special herbicide for a nursery hedge. The weeding composition is composed of threeeffective components A, B and C, A is oxyfluorfen, B is any one of pendimethalin, metolachlor and S-metolachlor; and C is any one of quizalofop-p-ethyl, high-efficiency fluazifop-butyl, fluazifop-p-butyl and clethodim; and the weight ratio of A, B and C is (0.1-90) : (0.1-90): (0.1-90). The compound A, the compound B and the compound C are compounded, and the co-toxicity coefficient of the weeding composition is 120, the weeding composition has a synergistic effect; and the weeding composition is good in prevention and treatment effects and fast in effectiveness, the weeds can be killed thoroughly, the gramineous and broad-leaf weeds can be removed, the use amount of the pesticides can be reduced, the drug resistance of weeds can be delayed, and the safety is high.

Description

technical field [0001] The invention relates to the technical field of herbicides, in particular to a herbicide composition and a special herbicide for nursery hedges. Background technique [0002] A nursery is a base for breeding and cultivating seedlings. Its task is to use advanced science and technology to cultivate high-quality seedlings of various types, specifications and purposes in a short period of time and at a low cost according to market demand, so as to meet the needs of urban and rural greening. Hedgerows are densely planted by shrubs or small trees with a close row spacing, planted in single or double rows, and closely combined in a regular planting form. Because of the selected tree species, it can be trimmed into various shapes and combined with each other, thus improving the ornamental effect and artistic value; in addition, the hedge can also play the role of covering bad viewpoints, isolating protection, preventing dust and noise, and guiding tourists t...
