Pinellia ternata post-seedling herbicide mixture and use method thereof

Abstract

The invention discloses a pinellia ternata post-seedling herbicide mixture and a use method thereof. The prepared pinellia ternata post-seedling herbicide mixture consists of ethyl carboxyflurane andquizalofop-p-ethyl, wherein the ethyl carboxyflurane is processed by the following raw materials in part by weight: 6-12 parts of ethyl acetate, 30-42 parts of acifluorfen and 10-14 parts of emulsifying agent. In the pinellia ternata post-seedling herbicide mixture and the use method thereof, by mixing the carboxyflurane and the quizalofop-p-ethyl according to a ratio of 4:1, pinellia ternata post-seedling weeds are safely and effectively controlled and removed; the application cost investment of the pinellia ternata post-seedling herbicide mixture is about 100 yuan, so that the cost per mu can be saved by about 400 yuan; by the use of a pinellia ternata post-seedling herbicide composition, gramineous weeds and robad-leaved weeds can be effectively controlled and removed; by the combined use of two herbicides, the dosage is reduced, the drug damage is avoided, and drug residues are reduced, therefore, safety and reliability are realized; the use method is simple, the investment cost islow, and control and removal effects are obvious.

Description

technical field [0001] The invention relates to the technical field of herbicides, in particular to a herbicide mixture for post-emergence Pinellia field and its use method. Background technique [0002] With the continued stability of the pinellia market, the large-scale planting area is increasing, especially in Guizhou. Since Hezhang Pinellia passed the geographical indication certification of the General Administration of Inspection and Quarantine, the scale of pinellia planting has continued to expand, and it has become a poverty alleviation tool in the Bijie test area. The main industry of the tackling strategy, but in recent years, in the process of large-scale planting of pinellia, weeds in Pinellia fields are flooded, and the cost of manual weeding is too high. Herbicides are divided into killing and selective herbicides according to their functions. Most of the derivatives of nitrophenol, chlorophenol or carbamic acid are effective. The development of herbicides in...

[0002] With the continued stability of the pinellia market, the large-scale planting area is increasing, especially in Guizhou. Since Hezhang Pinellia passed the geographical indication certification of the General Administration of Inspection and Quarantine, the planting scale of pinellia has continued to expand, and it has become a poverty alleviation in the Bijie test area. The main industry of the tackling strategy, but in recent years, in the process of large-scale planting of pinellia, weeds in Pinellia fields are flooded, and the cost of manual weeding is too high. Herbicides are divided into killing and selective herbicides according to their functions. Most of the derivatives of nitrophenol, chlorophenol or carbamic acid are effective. The development of herbicides in the world is gradually stabilizing, mainly developing varieties with high efficiency, low toxicity, broad spectrum and low dosage, and disposable treatment agents with little environmental pollution are gradually It has become the mainstream, so there is an urgent need to provide a safe, low-cost, and effective post-emergence weeding program for pinellia bases and large growers.
