Embodiment 1

[0021] Embodiment 1 is a dosage form preparation example, and embodiment 2 is a biological embodiment,

[0022] Example 1

[0023] a: wettable powder

[0024] A composition of 20 parts by weight of bentazone and fenmetrazone, 2 parts by weight of sodium dodecylbenzenesulfonate as a wetting agent, and 5 parts by weight of sodium lignosulfonate as a dispersant , 15 parts by weight of white carbon black used as an inert filler and 58 parts by weight of kaolin are ultrafinely pulverized in a jet mill.

[0025] b: water dispersible granules

[0026] The composition of 70 parts by weight of bentazone and fenmetrazone and 2 parts by weight of sodium dodecylbenzenesulfonate used as wetting agent, 10 parts by weight of carboxylate used as dispersant, 3 parts by weight Part by weight of sulfonate used as a wetting agent and 15 parts by weight of kaolin used as a filler are jet-milled, kneaded with an appropriate amount of water, granulated and dried.

[0027] c: suspending agent

...

Embodiment 2

[0029] Example 2, the control effect of bentazone and fenmetazone mixed on weeds in cornfield

[0030] Location: Jiangsu, Xinyi

[0031] Application period: Weed 2-3 leaf stage investigation: 30 days after application: 2011

[0032]

[0033] Conclusion: The actual control effect of the mixed use of Bentazone and fenmetazone is higher than the expected theoretical control effect of the combination, and at the same time it can expand the herbicidal spectrum. .

Abstract

The invention belongs to an improved weeding composition, and relates to a preparation method and purposes. The weeding composition is a mixture of compounds bentazone and topramezone. The weeding composition can effectively prevent annual grassy weeds and broad leaf weeds in a corn field. The control effects of the weeding composition are remarkably higher than those of bentazone or topramezone, and application doses of a plurality of active substances are greatly reduced.

Description

Technical field: [0001] The present invention relates to herbicidal compositions having improved properties. Background technique: [0002] The chemical name of the compound bentazon is 3-isopropyl (1H)-benzo-2,1,3-thiadiazin-4-(3H)-one 2,2 dioxide, and the common name in English has bentazon ( ANSI, CSA, WSSA) bentazone (ISO, BSI, JMAF); Bendioxide (So. Africa). The trade names include Pai Cao Dan; Benda Song; Bentazon; Basagran; bendioxide; Entry; Leader; Pledge. CA Registry No. 25057-89-0, EEC No. 246-585-8. Bentazon was first reported by A. Fischer for its herbicidal activity (Proc. 9th Br. Weed Control Conf., 1968, p. 1042), and was popularized by Badische Anilin-and Soda-Fabrik AG in 1972. [0003] Bentazone is a contact herbicide. It can be used to control soybeans, corn, peas, rice fields Abutilon, shepherd's purse, iron water chestnut, thornless mandala, sunflower, Polygonum, purslane, ragweed, cocklebur, bermudagrass, heteromorphic Sedge, melon skin grass, tri...
