Abstract
Agriculturally acceptable pesticidally active ingredients, such as herbicides, fungicides, and insecticides of low melting point, typically in the range from about 30.degree. C. to about 130.degree. C. and preferably in the range from about 30.degree. C. to about 90.degree. C. and low water solubility, typically in the range from about 0.01 ppm to about 1000 ppm and preferably in the range from about 0.01 ppm to about 300 ppm are frequently formulated as water-dispersed agrichemically acceptable formulations such as wettable powders (WP), water-dispersible granules (WG), and suspension concentrates (SC) and the like.
Claims39
An aqueous, stable pesticidal suspension which comprises:
- a low melting temperature pesticide active ingredient;
- a nucleating agent selected from the group consisting of carboxylic acids, esters, and amides having a melting point in the range from about 30.degree. to about 130.degree. and having a chain length in the range from about 3 to about 30;
- water;
- and
- a plurality of porous carrier particles dispersed in said water, said particles having mean size in the range from 2 to 20 .mu.m, said active ingredients being crystallized in said porous carrier particles and said active ingredient containing said nucleating agent.
A porous carrier composition containing a low melting pesticide, said composition comprising:
- a pesticide having a low melting temperature;
- a nucleating agent selected from the group consisting of carboxylic acids, esters and amides, said agent having a melting point in the range from about 30.degree. to about 130.degree. C. and having a chain length in the range from about 3 to about 30;
- and,
- a plurality of porous carriers, said pesticide being in crystallized form in said porous carrier, said crystallized pesticide containing said nucleating agent.
A suspendable water-dispersible composition containing a low melting temperature pesticide, said composition comprising:
- a plurality of porous carrier particles, said particles having mean size from 2 to 20 .mu.m;
- p1 a low melting temperature pesiticide, said pesticide being crystallized in said porous carrier particles;
- a nucleating agent in said pesticide, said nucleating agent selected from the group consisting of carboxylic acids, esters and amides, said agents having a melting point in the range from about 30.degree. to about 130.degree. C. and having a chain length in the range from about 3 to about 30.
