Tablet formulations of pesticides

A tablet formulation consisting essentially of, by total weight of the formulated composition:

• (i) 20% to 75% of a pesticide or growth regulant having a melting point of at least 100.degree. C. and a water solubility at 20.degree. C. of no more than 5% by weight, and
• (ii) 25% to 80% of a delivery system characterized by a panel of components complementary to the pesticide of (i) that consists essentially of the following components:
• (a) 5% to 20% of a dibasic or tribasic organic carboxylic acid or a mixture thereof;
• (b) 7% to 50% of an ammonium or alkali metal carbonate or bicarbonate or a mixture thereof;
• (c) 0.5% to 20% of a dispersant,
• (d) about 0.1% to 5% of water-insoluble cross-linked polyvinylpyrrolidone, and
• (e) 0.1% to 5% of an anionic or nonionic wetting agent;
• the formulation forming a dispersion in water, fine enough to pass a 50 mesh screen without clogging it and having a specific gravity greater than 1.00.
