Embodiment 1

[0017] Embodiment one: Tests for determination of joint action types on annual weeds in paddy fields.

[0018] Test material: Chickweed[ Stellaria media (L.) Cyrillus] (seed collection in field preservation). barnyard grass [ Echinochloa crusgalli (L.) Beaw Setaria] (field collection of seeds for preservation).

[0019] Test equipment: controllable light incubator; POTTER precision laboratory spray tower; electronic balance (sensitivity 0.1mg); micropipette gun, etc.

[0020] Test method: First weigh a certain quality of 96% penoxsulam technical and 95% clomazone technical, add acetone to fully dissolve, then dilute with 0.1% Tween 80 aqueous solution, and prepare single-dose mother solutions respectively. Set a series of proportions for the purpose of mixing, and set 5 to 7 concentration gradients for each proportion. Select representative sensitive weed seeds according to the single-dose herbicidal spectrum for future use. After the treatment with the selected numbe...

Abstract

The invention discloses a penoxsulam-clomazone pesticide composition. The penoxsulam-clomazone pesticide composition comprises a common auxiliary agent, penoxsulam and clomazone, wherein the mass ratio of the penoxsulam to the clomazone is 20:1-1:30, preferably 10:1-1:20. After the penoxsulam is compounded with the clomazone, the synergistic effect is obvious, the dosage of the pesticide composition is obviously less than that of single use of the component, and the penoxsulam-clomazone pesticide composition is applicable to controlling annual weeds in dry-land raised rice seedling field.

Description

technical field [0001] The pesticide composition of the present invention uses penoxsulam and clomazone as active ingredients, and is used for preventing and controlling farmland weeds, especially for controlling annual weeds and the like in rice dry-raised seedling fields. Background technique [0002] Chemical weeding is one of the main means of controlling weeds in agriculture. In recent years, due to the large-scale single use of some herbicide varieties, many weeds have developed resistance. At the same time, when weeds occur, the grass phase is complex, not only annual and perennial weeds are mixed, herbs, vines and shrubs are mixed, but also the emergence of weeds is uneven, and the seeds, young and old weeds are staggered, so the herbicide species alone When used, all will show some defects and limitations. [0003] Penoxsulam is a broad-spectrum herbicide for post-emergence paddy fields. It can effectively control barnyard grass, stephae and annual Cyperaceae weed...
