Embodiment 1

[0026] Test name: Indoor activity test of tembotrione, clomazone and isoproturon mixed with weeds.

[0027] Purpose of the test: Through the greenhouse pot activity assay test, the synergistic effect of the mixed use of tembotrione, clomazone and isoproturon on weeds is more clear, and the weed control between the compositions and between the composition and a single agent is further compared Activity, in order to better illustrate the herbicidal composition of the present invention.

[0028] Test target: Rice Lishihe was selected as the test target.

[0029] Test agents: 97.4% tembotrione TC, 95% clomazone TC and 98% isoproturon TC.

[0030] Test medicament and preparation: Weigh a certain amount of the original drug, choose a suitable organic solvent to dissolve it to make a mother liquor, and dilute it with distilled water containing 0.1% Tween-80 to make a test dose according to the set dose for treatment.

[0031] Cultivation of test materials: The soil used for the tes...

preparation Embodiment

[0040] In the following examples, 97.4% tembotrione TC, 95% clomazone TC and 98% isoproturon TC are used as the active ingredients, and the percentages of each component are weight percentages.

[0041] Example 1: 9% tembotrione. clomazone. isoproturon (0.6:2.1:6.3) floating granules

[0042]Liquid phase A was obtained by dissolving 2.1 kg of clomazone technical product, 3 kg of thick milk 500#, and 2 kg of Ningru 34# in 10 kg of methyl oleate. Put 0.6 kg of tembotrione technical material, 6.3 kg of isoproturon technical material, 1 kg of wetting agent EFW, 4 kg of dispersant NNO, and 40 kg of kaolin into a mixing kettle, mix evenly, and then jet mill to obtain powder phase B. Add expanded perlite with a particle size of 1 to 2 mm in the disc granulator, add liquid phase A for adsorption during the rotation process, add powder phase B after the adsorption is uniform and continue to rotate and adsorb, and sieve the particles after the adsorption is uniform to obtain Floating g...

Embodiment 2

[0043] Example 2: 9% tembotrione. clomazone. isoproturon (0.9:2.1:6.3) granules

[0044] Mix 2.1 kg of clomazone, 3 kg of methyl oleate, 1.5 kg of concentrated milk 500# and 0.9 kg of Ningru 34#, and then absorb with 3.5 kg of white carbon black to obtain powder phase A. Put 0.6 kg of tembotrione technical, 11 kg of powder phase A, 6.3 kg of isoproturon technical, 1 kg of wetting agent EFW, 4 kg of dispersing agent NNO, 0.5 kg of adhesive CMC, and 100 kg of kaolin into the mix After mixing uniformly in the kettle, jet milling is obtained to obtain a powder, and then water is added to knead and granulate and dried to obtain a granule.

Abstract

The invention discloses a compound herbicidal composition. The compound herbicidal composition includes three effective components, namely tembotrions, clomazone and isoproturon, in the mass ratio of (0.4-1.0):(1-4):(1-10), and the sum of the mass ratios of the three effective components in the composition is 1-60%. The herbicidal composition is suitable for controlling the majority of grassy weeds and broadleaf weeds in a paddy field, especially has a good control effect on leerisia orygoides, the lasting period is long, the use is convenient, and the compound herbicidal composition has no harm to rice.

Description

technical field [0001] The present invention relates to a herbicidal composition and its application. In particular, it relates to a herbicidal composition compounded by three active ingredients of tembotrione, clomazone and isoproturon, which belongs to the technical field of pesticides. Background technique [0002] Tembotrione, chemical name 2-{2-chloro-4-methylsulfonyl-3-[(2,2,2-trifluoroethoxy)methyl]benzoyl}cyclohexane-1 , 3-diketone is a triketone cornfield herbicide developed by Bayer in 2007. It is mainly used in cornfields and is a post-emergent HPPD (p-hydroxyphenylpyruvate dioxygenase) inhibitor herbicide. Block the biosynthesis of prenyl quinone in plants, causing chlorosis, discoloration, tissue necrosis, and finally death within 2 weeks. Teratrione has a wide weeding spectrum and a long suitable period for weeding. It mainly controls various broad-leaved weeds and grass weeds in the middle and late stages of corn fields after budding. It is one of the most ...
