Problems solved by technology

[0004] In the production of melons, whether 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; 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 the melon 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 · rimsulfuron tetrazole effervescent granules (5:1), including the following components by weight: (based on 100 kg, the same below)

[0038]

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

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

[0041] (2) Under the conditions of constant temperature of 15°C-25°C and constant humidity of 20%-25%, add the wrapping agent to absolute ethanol according to the ratio of wrapping agent: absolute ethanol = 1:2, stir and heat until wrapped The agent is completely dissolved and transparent, and the ethanol solution of the encapsulation agent is obtained;

[0042] (3...

Embodiment 2

[0048] 2.2% mesotrione · rimsulfuron-methyl tetrazole granules (6.35:1), including the following components by weight:

[0049]

[0050] The special-purpose herbicide composition granule for planting melons is prepared by an adsorption granulation method, and the following steps are adopted:

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

[0052] (2) In the process of constantly stirring the filler, evenly spray the dispersible oil-suspension concentrate prepared in step (1) on the filler in the form of a spray, and then completely absorb the dispersible oil-suspension concentrate through the filler to obtain the herbicidal Dosage Composition Granules.

Embodiment 3

[0054] 17% mesotrione · rimsulfuron tetrazole effervescent granules (5.8:1), including the following components by weight:

[0055]

[0056] The preparation method of the special herbicide composition effervescent granule for planting melon is the same as in Example 1.

Abstract

The invention belongs to the technical field of agriculture, and particularly discloses a special herbicide composition for melon planting and a preparation method thereof. The special herbicide composition for planting melons comprises 0.1% to 25% of active ingredients accounting for the total weight of the herbicide composition and 0% to 70% of auxiliaries accounting for 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 muskmelon planting provides a convenient granule and effervescent granule for controlling weeds in muskmelon planting; the prepared granule has good control effect on weeds in muskmelon 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, in particular to a special herbicide composition for melon planting and a preparation method thereof. [0003] 【Background technique】 [0004] In the production of melons, whether 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; 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 the melon to compete for glory, fertilizer, and water are large; the fourth is that the reproduction of weeds induces pests and diseases. Therefore, attention should be paid to the removal of weeds in melon cultivation. [0005] 【Content of invention】 [0006] The invention provides a special herbicide composition ...
