Abstract
Stable aqueous spore-containing chemical formulations having a low to medium viscosity profile are provided. The formulations comprise at least one spore in a mixture of water and at least one water miscible solvent, optionally at least one surfactant, optionally at least one stabilizer such as a metal salt, optionally at least one biocide, optionally at least one buffer, and optionally at least one chemical insecticide or fungicide or a mixture thereof. The formulations are particularly suitable as a seed coating and foliar spray. Methods of preparation as well as methods of treating a plant are also provided.
Claims18
An agriculturally acceptable stable aqueous formulation comprising
- (a) at least one spore present in an amount of from 3% w/w to 80% w/w,
- (b) at least one water miscible solvent and/or at least one aqueous emulsion of a hydrophobic agent, in an amount of 2 to 90% w/w, and
- (c) balance water.
A method of protecting a plant comprising:
- (a) providing an aqueous formulation, the formulation comprising
- at least one spore in an amount of from 3% w/w to 80% w/w;
- at least one water miscible solvent and/or an aqueous emulsion of a hydrophobic agent in an amount of 5% w/w to 50% w/w,
- from 1% w/w to 60% w/w of an insect control agent, pesticide and/or fungicide,
- optionally, from 0.2% w/w to 20% w/w of at least one nonionic surfactant;
- optionally, from 0.1% w/w to 10% w/w of at least one anionic surfactant or wetting agent;
- optionally, 0.1% w/w to 20% w/w of at least one polymeric dispersant;
- optionally, from 0.5% w/w to 20% w/w of at least one stabilizer of alkaline or alkaline earth metal or salt of aluminum, ammonium, zinc and/or iron;
- optionally, from 0.5% w/w to 10% w/w of at least one suspension aid;
- optionally, from 0.1% w/w to 10% w/w of at least one biocide;
- optionally, from 5% w/w to 30% w/w of at least one adjuvant;
- optionally, at least one buffer;
- and
- water in sufficient amount to bring the total to 100% w/w;
- and
- (b) applying the formulation to the plant in an effective amount.
