Bacillus mycoides isolate J (BmJ) induced resistance provides control of bacterial, fungal, oomycete and viral pathogens on a wide range of crop plants. BmJ induced resistance is signaled through the NPR -1 gene and involves several PR proteins and ethylene. Optimal systemic resistance induction occurs 3-5 days after application of live cells and provides disease control for 14-21 days depending on the plant induced. BmJ is compatible with pesticides including; triazole, EDBC, and QoI class fungicides and a wide range of insecticides. Disease control equal to commercial standards has been achieved with BmJ alone or in combination with fungicides where BmJ replaces half the fungicide used in fungicide alone programs. BmJ has also been demonstrated to be of benefit to triazole and QoI fungicide resistance management programs in Cercospora leaf spot of sugarbeet control programs. BmJ used in combination with insecticides and rouging has produced >50% control of potato PVY in multiple years in the field. Research results also support disease control in cucurbit crops, tomato, pepper, potato, pecans, spinach, lettuce and sugarbeet with comparisons to commercial pesticide standards. BmJ is licensed to CERTIS USA by Montana State University and will be sold as a WDG formulation. Application rates are based on 1 x 107cfu/ml ( 60-240 gm/A depending on spray volume). Registration is expected with Canada’s Pest Management Registration Authority (PMRA), the USEPA.
