Embodiment 3

[0046] Example 3 (Tebisulfone·thiatonsulfuron·octanoyl bromoxynil water-dispersible granules).

[0047]

[0048] Put the above materials together into the conical mixer and mix them evenly, and then crush them through the jet mill, and then mix the crushed materials through the conical mixer. Knead into a plastic material, and finally put this material into an extrusion granulator to extrude and granulate. After granulation, it is dried and sieved to obtain the corresponding weight percentage of tembotrione thiatonsulfuron octanoyl bromide Benzonitrile water dispersible granules.

Abstract

The invention discloses a herbicide for a corn field. The herbicide is composed of an effective ingredient A, an effective ingredient B, an effective ingredient C and a proper pesticide auxiliary. The effective ingredient A is tembotrions, the effective ingredient B is selected from one of thiencarbazone-methyl and nicosulfuron, and the effective ingredient C is bromoxynil octanoate. The composite is composed of, by weight, 1%-40% of the effective ingredient A, 1%-10% of the effective ingredient B, 1%-40% of the effective ingredient C and the balance the pesticide auxiliary. By means of the herbicide, the weeding effect is improved, the herbicide controlling spectrum is enlarged, low toxicity and low residues are achieved, the herbicide using amount, the herbicide using frequency and the use cost are obviously reduced, the effect of the composite is obviously better than that of single dosages, and the herbicide a good novel composite agentia for preventing and removing annual weeds of the corn field.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and specifically relates to a synergistic response herbicide with tembotrione, thionsulfuron-methyl or nicosulfuron, and bromoxynil octanoyl as active ingredients, which is suitable for controlling annual weeds in corn fields . Background technique [0002] Tembotrione is a triketone selective herbicide, which can effectively control the main broad-leaved grasses and some grass weeds, such as velvetleum, amaranth, quinoa, Polygonum, barnyardgrass, crabgrass, etc. Good control effect, can be used for pre-emergence sealing treatment and post-emergence stem and leaf treatment. [0003] Thiencarbazone-methyl is a sulfonylaminocarbonyl triazolinone herbicide and an acetolactate synthase inhibitor. Thiensulfuron-methyl can effectively control grass weeds in corn fields such as crabgrass, goosegrass, barnyardgrass, foxtail, etc. and most broad-leaved weeds. It is registered for use in corn (field, ...
