Mixtures of mustard plant material for the control of pests and methods of making
A composition for controlling pests comprising a mixture of plant material obtainable from a mustard plant of the species Sinapis alba and plant material obtainable from a mustard plant of the species Brassica juncea is described.
1. A composition for controlling fungicidal pests comprising a mixture of (a) a plant material obtained from a mustard plant of the species Sinapis alba comprising from about 0.3% to about 15% (w/w) of the mixture, and (b) a plant material obtained from a mustard plant of the species Brassica juncea comprising from about 99.7 to about 85% (w/w) of the mixture, and said composition comprising an effective amount of a glucosinolate breakdown product.
2. The composition according to claim 1 wherein the plant material obtained from a Sinapis alba mustard plant, or from Brassica juncea mustard plant is a processed plant material.
3. The composition according to claim 1 wherein the plant material obtained from a Sinapis alba mustard plant, or from Brassica juncea mustard plant is a mustard seed.
4. The composition according to claim 1 wherein the plant material obtained from a Sinapis alba mustard plant, or from Brassica juncea mustard plant is a seed meal.
5. The composition according to claim 1 further comprising a carrier.
6. The composition according to claim 1 wherein the glucosinolate breakdown product is an allyl thiocyanate, allyl isothiocyanate, allyl cyanide, 1-cyano-2-hydroxy-3-butene, goitrin or a hydroxyl benzol.
