2-methyl-4-chlorophenoxy acetic acid and 2-methyl-4-chlorophenoxy acetic acid salt water-dispersible granule or tablet and preparation method thereof

Abstract

The invention discloses a 2-methyl-4-chlorophenoxy acetic acid and 2-methyl-4-chlorophenoxy acetic acid salt water-dispersible granule or tablet and a preparation method thereof. The 2-methyl-4-chlorophenoxy acetic acid and 2-methyl-4-chlorophenoxy acetic acid salt water-dispersible granule or tablet consists of the following materials in percentage by weight: 0.1 to 80 percent of 2-methyl-4-chlorophenoxy acetic acid and 2-methyl-4-chlorophenoxy acetic acid salt, 0.5 to 15 percent of dispersing agent, 0.5 to 8 percent of wetting agent, 0.1 to 35 percent of disintegrating agent, 0 to 10 percent of binder and the balance filler. The preparation method of the 2-methyl-4-chlorophenoxy acetic acid and 2-methyl-4-chlorophenoxy acetic acid salt water-dispersible granule or tablet includes the following steps: all the materials of the 2-methyl-4-chlorophenoxy acetic acid and 2-methyl-4-chlorophenoxy acetic acid salt water-dispersible granule or tablet are mixed, ultra-finely milled by jet, pelletized, dried, granulated or tableted, chosen and inspected, and thereby the 2-methyl-4-chlorophenoxy acetic acid and 2-methyl-4-chlorophenoxy acetic acid salt water-dispersible granule or tablet is obtained. The 2-methyl-4-chlorophenoxy acetic acid and 2-methyl-4-chlorophenoxy acetic acid salt water-dispersible granule or tablet is safe for the environment, the human being, livestock and other beneficial organisms, cannot easily produce chemical hazards, can be accurately weighed, and is convenient to use; the 2-methyl-4-chlorophenoxy acetic acid and 2-methyl-4-chlorophenoxy acetic acid salt water-dispersible granule or tablet can be rapidly disintegrated; the storage stability of the 2-methyl-4-chlorophenoxy acetic acid and 2-methyl-4-chlorophenoxy acetic acid salt water-dispersible granule or tablet is high, the preparation process is simple, and the 2-methyl-4-chlorophenoxy acetic acid and 2-methyl-4-chlorophenoxy acetic acid salt water-dispersible granule or tablet is suitable for industrialized production and wide popularization and application.

Description

Technical field: [0001] The invention relates to a water-dispersible granule / or tablet of a plant growth regulator and a preparation method thereof, in particular to a dimethyltetrachloride and dimethyltetrachloride salt water dispersible granule / or tablet and a preparation method thereof. Background technique: [0002] In agriculture, it is used as a plant growth regulator to prevent early flower and fruit drop of tomatoes and other fruits, and form seedless fruits, promote early maturity of crops, and accelerate rooting of cuttings. It can also be used as a herbicide, which is easily absorbed and conducted by stems and leaves. It is used for post-emergent control of various annual and perennial broad-leaved weeds in small grains, rice, peas, lawns and non-cultivated areas. This product has special effects on broad-leaved and triangular grasses, and can also control various dicotyledonous and some monocotyledonous weeds, but it is ineffective against barnyard grass.
