Problems solved by technology

However, herbicides are a double-edged sword. During the use of herbicides, due to their own characteristics and processing quality problems, backward technology used by users, and poor environmental conditions, etc., they will also cause negative effects such as phytotoxicity on crops.

preparation example Construction

[0060] The third aspect of the present invention provides the preparation method of the dispersible oil suspension concentrate, comprising the following steps: mixing, shearing and grinding the herbicidal composition, adjuvants and dispersion medium to obtain the finished product.

[0061] In a preferred embodiment, the preparation method of the dispersible oil suspension comprises the following steps: mixing the herbicidal composition, dispersant, emulsifier, wetting agent, thickener antifreeze agent and dispersion medium, Shear and disperse for 10-60 minutes; then grind it with a sand mill until the D97 is 1-10 μm.

[0062] In a more preferred embodiment, the D97 is 3±1 μm.

[0063] D97 refers to the corresponding particle size value when the cumulative distribution percentage from small to large reaches 97% in the particle size distribution. That is to say, in a certain powder, the number of particles with a particle size smaller than D97 accounts for 97% of the total numb...

Embodiment 1

[0070] Embodiment 1 provides an aqueous solution of a herbicidal composition, the herbicidal composition is isoxaflutole and terbuthylazine, the concentration of the isoxaflutole is 3.75g / L; The concentration is 25g / L.

Embodiment 2

[0072] Embodiment 2 provides an aqueous solution of a herbicidal composition, the herbicidal composition is isoxaflutole and terbuthylazine, the concentration of the isoxaflutole is 3.75g / L; The concentration is 50g / L.

Abstract

The invention relates to the technical field of pesticides, in particular to a weeding composition and application thereof. The invention relates to a weeding composition, which comprises isoxaflutoleand terbuthylazine, and the weight ratio of isoxaflutole to terbuthylazine is 1: (0.1-150). The weeding composition provided by the invention is environment-friendly, has no harm to crops, has no influence on next-stubble crops, generates a synergistic effect through the combined effect of the two herbicides with different weeding mechanisms on weeds, reduces the dosage, expands the weeding spectrum, improves the prevention effect and overcomes the defect of poor prevention effect of a single agent on main weeds; the weeding effect is remarkable, and the weeding effect on piemarker, quinoa, green bristlegrass and crab grass is especially excellent. Besides, the raw materials of a prepared dispersible oil suspending agent form a synergistic effect, so that the dispersible oil suspending agent has relatively high emulsifying dispersity and storage stability, is good in spreading permeability on crop surfaces during use, reduces loss of effective components, and has an obvious synergistic effect, thereby improving the medicinal effect of herbicides.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a herbicidal composition and its application. Background technique [0002] Pesticides play a very important role in the planting industry. The development of pesticides should have high efficiency, low toxicity, low residue and no pollution. Therefore, in the selection of pesticides, the pesticides of compound mixtures have naturally become the preferred and effective way at present. By adjusting the ratio of pesticides, the performance can be complemented, and the pesticides can get the best synergy. Herbicides play a huge role in protecting crops from weeds, promoting crop growth, and improving the quality and quality of agricultural products. They have rapidly developed into an important means of agricultural weeding and have been rapidly popularized and applied in production. However, herbicides are a double-edged sword. During the use of herbicides, due to their own cha...
