Embodiment 1

[0035] Example 1 70% Hexazinone·Imazazole Water Dispersible Granules

[0036] The formula is: hexazinone 58.3%, imazethapyr 11.7%, polycarboxylate sodium salt 3%, calcium lignosulfonate 1.5%, sodium lauryl sulfate 1%, sodium lignosulfonate 1%, ammonium sulfate 0.75%, urea 0.5%, white carbon black to 100%.

[0037] The preparation method is as follows: mix hexazinone, imazethapyr, dispersant, wetting agent, disintegrant, and filler in a mixer evenly, pulverize it with a jet mill to a particle size of 20-40 μm, then mix evenly, and knead Add 20-30% water, carry out extrusion granulation, and dry at 40-60°C to make 70% water-dispersible granules.

Embodiment 2

[0038] Example 2 90% Hexazinone·Izaniacin Water Dispersible Granules

[0039] The formula is: hexazinone 45%, imazethapyr 45%, sodium polycarboxylate 3%, calcium lignosulfonate 1.5%, sodium lauryl sulfate 1%, sodium lignosulfonate 1%, ammonium sulfate 0.75%, urea 0.5%, white carbon black to 100%. The preparation method is the same as in Example 1.

Embodiment 3

[0040] Example 3 30% Hexazinone·Izaniacin Water Dispersible Granules

[0041] The formula is: hexazinone 5%, imazethapyr 25%, sodium polycarboxylate 3%, calcium lignosulfonate 1.5%, sodium lauryl sulfate 1%, sodium lignosulfonate 1%, ammonium sulfate 0.75%, urea 0.5%, white carbon black to 100%. The preparation method is the same as in Example 1.

Abstract

The invention discloses a weeding composition containing hexazinone and imazapyr and application of the weeding composition. The composition has a remarkable synergistic effect through compounding of the hexazinone and the imazapyr. The composition can be used for controlling and eliminating annual and perennial weeds one time and has excellent control effects on deep rooting plants, vine plants, bushes and the like, a weeding spectrum is expanded, the insecticide resistance of main weeds as well as the resurgence of secondary weeds are delayed, the service life of insecticides is prolonged, and environmental pollution is lowered. The weeding composition has the important economical, environmental and ecological significance.

Description

technical field [0001] The invention relates to a pesticide composition, in particular to a herbicidal composition containing hexazinone and imazethapyr and its application, and belongs to the technical field of pesticides. Background technique [0002] Hexazinone, chemical name: 3-cyclohexyl-6-dimethylamino-1-methyl-1,3,5-triazine-2,4-dione, also known as Wilbur. Hexazinone is a systemic selective herbicide, which can be absorbed by plant roots and leaves. It is mainly transmitted through xylem and does not harm the roots of pine trees. It is an excellent forest herbicide and is used for young evergreen coniferous forests. Weeding and irrigation before afforestation, maintenance of forest fire lines and forest stand transformation, etc., can prevent most monocotyledonous and dicotyledonous weeds and woody plants such as honeysuckle, pearl plum, hazelnut, willow-leaf spirea, thornwort, Aspen, birch, linden, Fraxinus mandshurica, yellow pomegranate, walnut, etc., but the eff...
