Biopesticide compositions comprising water soluble polyols
View Patent ↗Provided are liquid compositions comprising inactive biopesticide precursors comprising a glucosinolate concentrate, a plant material comprising a myrosinase enzyme complex, and a water soluble polyol. Further provided are methods of making and using such compositions.
1. A method for making a liquid composition comprising an inactive biopesticide precursor comprising mixing:
(a) a glucosinolate concentrate;
(b) a plant material comprising an active myrosinase complex in a concentration sufficient to release an effective amount of glucosinolate breakdown products upon the addition of water; and
(c) a water soluble polyol,
to obtain a liquid composition substantially free of glucosinolate breakdown products.
2. The method according to claim 1 wherein the plant material is a seed meal.
3. The method according to claim 1 wherein the plant material is a mustard seed meal.
4. The method according to claim 1 wherein the water soluble polyol is at least about 80% pure.
5. The method according to claim 1 wherein the liquid composition additionally comprises at least about 1% water and up to about 20% water.
6. The method according to claim 1 wherein the active myrosinase complex is present in a concentration of from about 1 unit to about 10 units per gram in the liquid composition and the glucosinolate is present from about 25 mg to about 500 mg per gram in the liquid composition.
