Embodiment 1

[0025] Weigh 10% thiadidiuron, 10% phenylpeptidamine, 3% Nongru 500#, 5% TX-10, 2% Nongru 1601#, 2% epichlorohydrin, 10% N-methylpyrrolidone, Cyclohexanone is added to 100% by weight. The above raw materials are mixed, stirred and dissolved completely to prepare 20% thiadizuron·phenylpeptidyl acid soluble solution.

Embodiment 2

[0027] Weigh 15% thiadizuron, 10% phenylpeptidyl acid, 4% TX-10, 5% Nongru 1601#, 15% dimethylformamide, and add acetone to 100% by weight. The above raw materials are mixed, stirred and dissolved completely to prepare a 25% soluble solution of thiadizuron·phenylpeptidyl acid.

Embodiment 3

[0029] Weigh 20% thiadizuron, 5% phenylpeptidyl acid, 8% Nongru 1601#, add deionized water to 100% by weight. The above raw materials are mixed, stirred and dissolved completely to prepare a 25% thiadizuron·phenylpeptine acid aqueous solution.

Abstract

The invention discloses a defoliant containing thidiazuron and phethalanilic acid and application thereof. The defoliant is prepared from a first active component thidiazuron, a second active component phethalanilic acid and an additive, wherein the weight ratio of the first active component to the second active component is (1 to 30) to (30 to 1), preferably (1 to 20) to (20 to 1) and more preferably (1 to 10) to (10 to 1); the sum of the contents of the first active component and the second active component is 1 to 60 percent of the total weight of the defoliant. The defoliant can be prepared to be in the dosage forms of agriculturally allowable soluble liquid, water, dispersible oil suspending agent, wettable powder, a water dispersible granule and a suspending agent. The defoliant usesa compositional formulation, is used for defoliating cotton and capsicum annuum, is obvious in synergistic effect and is safe to a crop; the medication amount and the medication times are reduced andthe prevention and treatment costs are decreased.

Description

technical field [0001] The invention relates to a defoliant, which is composed of the first active ingredient thiadizuron, the second active ingredient phenylpeptidyl acid and auxiliary agents, and belongs to the technical field of compound pesticides. Background technique [0002] Thidiazuron, English name thidiazuron, chemical name is 1-phenyl-3-(1,2,3-thiadiazol-5-yl)urea. Thidiazuron is a plant growth regulator used as a defoliant. After being absorbed by the leaves of cotton plants, it can promote the natural formation of the separation tissue between the petiole and the stem as soon as possible to cause the leaves to fall, which is beneficial to the mechanical harvesting of cotton and can make the cotton harvest about 10 days in advance, which helps to improve the cotton grade. [0003] Phenylpeptidic acid, the chemical name is o-(-N-benzoyl)benzoic acid. Phenylpeptidic acid is a biologically active plant growth regulator. Spraying on the leaves can quickly soak into...
