Abstract
A water dispersible gel comprising: (a) an effective amount of an ionic, water soluble agrochemical; (b) an effective amount of a cross-linked polyacrylic acid; (c) water; and, (d) an amount of a base sufficient to cause a mixture of (a), (b) and (c) to gel.
Claims13
A containerization system comprising a water dispersible gel contained in a water-soluble or water dispersible bag;
- the water dispersible gel comprising:
- (a) 1-60% by weight of an ionic, water-soluble agrocherical;
