Problems solved by technology

[0004] Most of the existing cornfield weeding uses herbicides containing one active ingredient, which is not only costly, but also has a relatively narrow herbicidal spectrum, which cannot achieve the purpose of controlling multiple weeds at one time

Embodiment 1

[0013] Example 1: Nicosulfuron, Bromoxynil Octanoyl and Fluroxypyr Compound Herbicide (8% dispersible oil suspension formulation)

[0014] (1) Formula: by weight percentage, nicosulfuron 2%, bromoxynil 5%, fluroxypyr 1%, urea 0.5%, 1-dodecylazepane-2- Ketone 2%, Nongru 1601 15%, turpentine-based vegetable oil 74.5%.

[0015] (2) Preparation method

[0016] 1) According to the above ratio, add various raw materials in proportion to the stirring tank and stir for 30 minutes, and shear at the same time during the stirring process;

[0017] 2) After stirring for 30 minutes, the material is ground by a sand mill. The qualified standard for grinding is that the material detection particle size D50 shall not be greater than 8 microns;

[0018] 3) After passing the grinding, transfer the material into the shearing kettle and shear for 30 minutes;

[0019] 4) After shearing, take samples for testing of various indicators in the laboratory;

[0020] 5) After passing the test, it ...

Embodiment 2

[0022] Example 2: Nicosulfuron, Bromoxynil Octanoyl and Fluroxypyr Compound Herbicide (24% Dispersible Oil Suspension Formulation)

[0023] (1) Formula: by weight percentage, nicosulfuron 4%, bromoxynil 15%, fluroxypyr 5%, urea 0.5%, 1-dodecylazepane-2- Ketone 2%, Nongru 1601 15%, pine resin-based vegetable oil 58.5%.

[0024] (2) The preparation method is the same as in Example 1.

Embodiment 3

[0025] Example 3: Nicosulfuron, bromoxynil octanoyl and fluroxypyr compound herbicide (38% dispersible oil suspension formulation)

Abstract

The invention relates to a herbicide compounded from nicosulfuron, bromoxynil octanoate and fluroxypyr. The technical scheme is as follows: the herbicide takes the nicosulfuron, the bromoxynil octanoate and the fluroxypyr as effective components, and the mass ratio of the nicosulfuron, the bromoxynil octanoate to the fluroxypyr is 1:(1-10):(0.5-3). The herbicide also comprises a stabilizing agent, a synergistic agent and / or a filling agent. The herbicide can be prepared into dosage forms, such as a dispersible oil suspending agent, wettable powder, a suspending agent, a water dispersible granule and soluble powder or missible oil, and the weight percentage of the effective components is 10%-50% in the dosage forms of the herbicide. The herbicide disclosed by the invention has obvious synergistic effect and the effect of increasing grass control speed after the nicosulfuron, the bromoxynil octanoate and the fluroxypyr are compounded, is low in toxicity and low in residue, enlarges the weed control spectrum, outstandingly reduces the dosage, the drug delivery times and the application cost and is favorable to prolonging the succession speed of a weed community and prolonging the service life of the herbicide.

Description

technical field [0001] The invention belongs to the field of herbicides, in particular to a compound herbicide mainly used for controlling annual weeds in corn fields. Background technique [0002] The use of chemical herbicides is one of the main measures for farmers to reduce labor intensity, effectively control weed damage in farmland, and obtain high yields of crops. For a long time to come, it is inevitable to use chemical herbicides to control field weeds , reduce labor intensity and increase crop yield. [0003] Corn is one of the three major food crops in the world. It has a long history of cultivation. It is a high-yield crop and a nutritious feed crop. It is known as the "king of feed". Cornfield weeds have a long period of occurrence, a large amount, and many types. In the current weed management system in cornfields, herbicides still play a very important role. Moreover, weeding in cornfields is also a complicated agricultural activity. Chemical weeding Can eff...
