Problems solved by technology

[0004] Strawberry production, whether it is in the breeding nursery or handed over to the field, weeds have been growing together, and the damage is serious. First, there are many types of weeds, and single-leaf weeds and broad-leaved weeds can breed; second, strawberry The amount of fertilization is large, and it is easy to fertilize and grow fierce grass; the third is that the weeds multiply quickly and the density is high, and the symbiosis conflicts with strawberries to compete for glory, fertilizer, and water are large; the fourth is that the reproduction of weeds induces pests and diseases

Embodiment 1

[0037] 12% Mesotrione·Sumesulfuron Tetrazosulfuron effervescent granules (5:1), including the following components in the following weights: (based on 100 kg, the same below)

[0038]

[0039] The preparation method of the herbicide composition effervescent granules special for strawberry planting: adopt the following steps:

[0040] (1) Under the condition of 15℃~25℃ constant temperature, 20%~25% constant humidity and humidity, add the binder to the absolute ethanol at the ratio of binder: absolute ethanol=1:2, stir and heat Until the binder is completely dissolved and transparent, an ethanol solution of the binder is prepared;

[0041] (2) Under the condition of 15℃~25℃ constant temperature and 20%~25% constant humidity and humidity, add the coating agent to the absolute ethanol at the ratio of coating agent: absolute ethanol = 1:2, stir and heat to wrap The agent is completely dissolved and transparent, and an ethanol solution of the coating agent is prepared;

[0042] (3) Mesotri...

Embodiment 2

[0048] 2.2% Mesotrione·Sumesulfuron-methyl granules (6.35:1), including the following components in the following weights:

[0049]

[0050] The herbicide composition granules special for strawberry planting are prepared by the adsorption granulation method, and the following steps are adopted:

[0051] (1) Mesotrione and sulfometuron, emulsifier, dispersant, stabilizer, and dispersion medium are weighed in proportion and cut in a shearing kettle for 40 minutes, and then placed in a series horizontal sand mill Continuous sand milling to a particle size D50<3μm to obtain a dispersible oil suspension concentrate;

[0052] (2) In the process of continuously stirring the filler, after the dispersible oil suspension agent prepared in step (1) is uniformly sprayed on the filler in the form of spray, the dispersible oil suspension agent is completely absorbed by the filler to obtain the herbicide Agent composition granules.

Embodiment 3

[0054] 17% Mesotrione·Sumesulfuron Tetrazosulfuron effervescent granules (5.8:1), including the following components in the following weights:

[0055]

[0056] The preparation method of the herbicide composition effervescent granules special for strawberry planting is the same as that of Example 1.

Abstract

The invention belongs to the technical field of agriculture, and particularly discloses a special herbicide composition for strawberry planting and a preparation method thereof. The special herbicide composition for strawberry planting includes 0.1% to 25% of active ingredients and 0% to 70% of the total weight of the herbicide composition, and the balance is fillers. The active ingredients are composed of mesotrione and rimsulfuron-methyl, and the weight ratio of the mesotrione and rimsulfuron-methyl is 1:10-80:1. The special herbicide composition for strawberry planting provides a convenient granule and effervescent granule for controlling weeds in strawberry planting; the prepared granule has good control effect on weeds in strawberry planting , used in conjunction with rimsulfuron-methyl, rimsulfuron-methyl can effectively improve the killing effect of mesotrione on weeds, and can be directly thrown into the planting nursery or mixed with fertilizer.

Description

[0001] 【Technical Field】 [0002] The invention belongs to the technical field of pesticides, and particularly relates to a herbicide composition special for strawberry planting and a preparation method thereof. [0003] 【Background technique】 [0004] In strawberry production, whether it is in the breeding nursery or handed over to the field, weeds always grow together, and the harm is serious. First, there are many types of weeds, and single-leaf weeds and broad-leaved weeds can breed; second, strawberries The large amount of fertilization makes it easy to fertilize the grass; the third is that the weeds multiply fast and the density is high, and the symbiotic contradiction of competing with strawberries for glory, fertilizer and water is large; fourth, the reproduction of weeds induces pests and diseases. Therefore, attention should be paid to the removal of weeds in strawberry planting. [0005] [Content of the invention] [0006] The invention provides a herbicide composition spec...
