Example Embodiment

[0019] Example 1: The herbicidal composition is an oil suspension concentrate, and the percentages of each component are:

[0020] Active ingredient A 1~30%,

[0021] Active ingredient B 1~30%,

[0022] Dispersant 2~10%,

[0023] Wetting agent 2~10%,

[0024] Thickener 0.1~2%,

[0025] Packing balance.

[0026] The specific operation steps are as follows: mix the active ingredients A and B, other additives and fillers, stir them evenly in a stirring tank, then pass through a jet flow mixer to shear and disperse until there are no visible solid particles, and finally in a ball mill The herbicidal composition oil suspension formulation of the present invention can be prepared by grinding for 2 to 3 hours to make the particle diameters below 5 μm.

Example Embodiment

[0027] Example 2: The herbicidal composition is a wettable powder, and the percentages of each component are:

[0028] Active ingredient A 1~30%,

[0029] Active ingredient B 1~30%,

[0030] Dispersant 2~10%,

[0031] Wetting agent 1~5%,

[0032] Packing balance.

[0033] The specific operation steps are: mixing the active ingredients A and B, other auxiliary agents and fillers, fully stirring in a stirring tank, pulverizing by a jet mill, and mixing uniformly to prepare a wettable powder formulation of the herbicidal composition of the present invention.

Example Embodiment

[0034] Example 3: The herbicidal composition is water dispersible granules, and the percentages of each component are:

[0035] Active ingredient A 1~30%,

[0036] Active ingredient B 1~30%,

[0037] Dispersant 5~15%,

[0038] Wetting agent 1~10%,

[0039] Disintegrant 1~5%,

[0040] Packing balance.

[0041] The specific operation steps are as follows: mix the active ingredients A and B, other additives and fillers evenly, pulverize with an ultra-fine jet mill, knead and add to the fluidized bed granulation dryer for granulation, drying, and sieving. Then, the water-dispersible granule preparation of the herbicidal composition of the present invention can be prepared.

[0042] The auxiliary agents in the above dosage forms are selected from the following.

[0043] The wetting agent can be dioctyl sulfosuccinate sodium salt, sodium butyl naphthalene sulfonate, fatty amide N-methyl taurine sodium salt, lignin sulfonate, alkylphenol polyoxyethylene ether phosphate, petroleum One or a mixtu...

Abstract

The invention relates to a weeding composition containing pyribenzoxim and pyrazosulfuron. The effective constituents are pyribenzoxim and pyrazosulfuron. The mass fraction ratio of pyribenzoxim to pyrazosulfuron is 1:20-20:1, and the preferred mass fraction ratio is 5:1-1:5. Compared with single usage of the pyribenzoxim or the pyrazosulfuron, the weeding composition not only can raise the weeding effects obviously and enlarge the weed control spectrum, but also can reduce the resistance risks caused by single usage. The weeding composition can reduce the usage frequency and the control cost, has good environmental compatibility, and is an ideal new-type composition for controlling weeds in paddy fields.

Description

technical field [0001] The invention relates to a pesticide herbicide composition, specifically a herbicide composition with saflufenacil and pyrazosulfuron-methyl as active ingredients, which is applied to the control of annual weeds in paddy fields. Background technique [0002] Rice is one of the main food crops in my country. There are many kinds of weeds in paddy fields. There are more than 200 kinds of weeds in the rice areas of the country, of which there are about 40 kinds of weeds that are common and seriously harmful. Therefore, weeding in paddy fields is an important aspect of production. a big problem. Chemical weed control is the main means of weed control. However, in recent years, due to the large-scale use of some herbicide varieties alone, many weeds have developed resistance. Therefore, there is an urgent need for new medicaments for weeding rice fields with high efficiency, low toxicity, economy and safety. [0003] Saflufenacil is a high-efficiency and...
