Problems solved by technology

[0006] (1) After the heat storage stability test, the particle size of diflusulam suspension concentrate will become larger, D 98 ≥5μm, the particle size of the system becomes larger, which is unfavorable for the stability of the product over time
[0007] (2) The diflusulam suspending agent foams seriously during the production process, and there are too many foams, which is not conducive to the packaging of the product

Embodiment 1

[0049] The 5% florasulam suspension concentrate obtained in Example 1 is applied to winter wheat fields to prevent and control annual broad-leaved weeds, the dosage of active ingredients is 3.75-4.5 g / ha, and 35 days after application, the overall plant control of broad-leaved weeds The control effect is 85.1%-89.7%, and the fresh weight control effect is 87.3%-92.6%, which is safe to winter wheat.

Embodiment 2

[0050] The 8% florasulam suspension concentrate obtained in Example 2 is applied to winter wheat fields to prevent and control annual broad-leaved weeds. The control effect is 87.5%-91.1%, and the fresh weight control effect is 88.6%-93.5%, which is safe for winter wheat.

Embodiment 3

[0051] The 10% diflusulam suspension concentrate obtained in Example 3 is applied to winter wheat fields to prevent and control annual broad-leaved weeds. The control effect is 86.2%-92.4%, and the fresh weight control effect is 85.9%-92.8%, which is safe to winter wheat.

Abstract

The invention discloses a florasulam suspension agent and a preparation method thereof. The florasulam suspension agent contains the ingredients in percentage by weight: 5% to 20% of florasulam, 1% to 8% of wetting dispersant, 1% to 10% of synergist, 3% to 6% of antifreezer, 1% to 3% of thickener, 0.1% to 1% of preservative, 0.1% to 1% of antifoamer and the balance of water. According to the preparation method of the florasulam suspension agent, disclosed by the invention, the antifoamer is added in batches, so that foam generated due to air admission during sanding is effectively eliminated. The florasulam suspension agent disclosed by the invention is environment-friendly and is high in suspension percentage, good in dispersity and good in stability, the preventive effect of florasulam on annual broadleaf weeds of winter wheat field is improved, and the preparation method is simple and convenient, so that industrial large-scale production is facilitated.

Description

technical field [0001] The invention relates to the field of agricultural herbicide suspensions, in particular to a florasulam suspension and a preparation method thereof. Background technique [0002] Florasulam (florasulam) is a triazolopyrimidine sulfonamide herbicide variety successfully developed by Dow AgroSciences. It is an ultra-efficient herbicide for post-emergence stem and leaf treatment of broad-leaved weeds in wheat fields. The mechanism is to prevent the biosynthesis of branched-chain amino acids by inhibiting the activity of acetolactate synthase, resulting in the destruction of protein synthesis, the cessation of cell mitosis, further leading to the cessation of plant growth and eventually death. The agent has a long-lasting effect and a wide herbicidal spectrum, and can effectively control most broad-leaved weeds such as pigtails and barley in wheat fields, and has a good inhibitory effect on the most difficult to control varnish in wheat fields; The drug e...
