Problems solved by technology

In terms of herbicide damage detoxification research, the current methods are: washing with water, early application of seedling fertilizer, topdressing quick-acting fertilizer, strengthening intertillage loosening, and application of special antidotes (such as isoxadifen, cyprosulfonamide, pyridoxine, etc.) Metofen-pyrrofen, Jieduquine, naphthylamine, etc.), spraying alkaline substances such as baking soda water, etc., but the above methods can only alleviate the slight herbicide damage, and basically have no effect on the severe herbicide damage
And the above-mentioned methods are all remedial measures taken after the herbicide injury occurs, and do not fundamentally solve the problem of the herbicide injury

preparation example Construction

[0062] A preparation method of a herbicide composition containing paclobutrazol is carried out according to the following steps. Each component is weighed according to the formula ratio and mixed to obtain the composition.

[0063] Application of the paclobutrazol-containing herbicide composition: it is used in paddy fields to control annual grass weeds or other family weeds.

[0064] As a further embodiment, the application of the paclobutrazol-containing herbicide composition: it is used for controlling grass weeds, broad-leaved weeds or sedges in paddy fields.

Embodiment 1

[0067] A herbicide composition containing paclobutrazol, made up of the following components by weight: 1 part of paclobutrazol, 11.5 parts of herbicides; wherein, said herbicide consists of 1.5 parts of penoxsulam and 10 parts of cyanogen Composition of Fluoxate.

[0068] The above paclobutrazol-containing herbicide composition is prepared into an oil suspension, and the amount of the paclobutrazol-containing herbicide composition accounts for 12.5% ​​of the total weight of the oil suspension.

[0069] The oil suspending agent is used for post-emergence prevention and treatment of resistant barnyardgrass in paddy fields, the dosage is 150 grams per mu, the control effect is over 95%, and it is safe for paddy rice.

Embodiment 2

[0075] A herbicide composition containing paclobutrazol, made up of the following components by weight: 4.5 parts of paclobutrazol, 30 parts of herbicides; wherein, said herbicide consists of 20 parts of quinclorac and 10 parts of saponin phosphorus composition.

[0076] The above paclobutrazol-containing herbicide composition is made into a dispersible oil suspension, and the dosage of the paclobutrazol-containing herbicide composition accounts for 34.5% of the total weight of the separable oil suspension.

[0077] The above-mentioned oil-separable suspending agent is applied to the direct seeding field to prevent and control gramineous weeds (barnyard grass), and the dosage is 150 grams per mu. After 25 days after direct seeding, the stems and leaves are treated, and the control effect is more than 95%, which is safe for rice.

Abstract

The invention discloses a herbicide composition containing paclobutrazol, a preparation method and application thereof. The herbicide composition containing paclobutrazol of the present invention is made up of the following components by weight: 1-99 parts of paclobutrazol, 1-90 parts of herbicide. The herbicides are cyhalofop-ethyl, penoxsulam, oxafenacil, bispyribac, quinclorac, sapon, bensulfuron-methyl, pyrazosulfuron-methyl, pyrimazafen, One or a mixture of two or more of grass pine, chlorpyrazosulfuron-methyl, bicyclic sulcotrione, dipenpyril, fluroxypyridine, 2-methyl-4-chloride, and fluroxypyr-ethyl isooctyl. The invention has a synergistic effect on weed control, improves the weeding efficiency, and can improve the safety of herbicides on crops, fundamentally solves the problem of herbicide phytotoxicity in agricultural production, and at the same time increases crop yield by regulating crop growth .

Description

technical field [0001] The invention relates to a herbicide composition, in particular to a paclobutrazol-containing herbicide composition and its preparation method and application. Background technique [0002] Herbicides are agents that kill weeds and protect crops, also known as herbicides. Herbicides are widely used in agriculture because of their low cost, high efficiency, easy operation, labor saving, and obvious weed control effects. However, improper use of herbicides often causes phytotoxicity to crops. When herbicides are used Excessive dosage, improper mixing, and abnormally bad environmental conditions will cause phytotoxicity to crops. Herbicide phytotoxicity leads to abnormal growth of crops, twisted stems and leaves, clumps, dwarfed plants, flowers but not fruit, and even dead seedlings and reduced yield. The herbicide's phytotoxicity is light and the yield is reduced by 10-40%, and the serious one is completely lost. With the development of agricultural s...
