Sweet Corn European corn borer (ECB) adult catches have become somewhat more consistent in southern NJ over the past week, but with very few individuals captured north of Burlington County (see ECB map). This late summer flight appears to be a fairly week one. As always, consider treating when the number of infested plants in […]

The first late blight fungicide application is recommended once 18 DSVs accumulate from green row. Green row typically occurs around the first week in May […]

Additional treatments will only be required on very late varieties, and only if trap counts exceed 6 moths per trap. We are seeing some high trap captures in some orchards. Tufted Apple Budmoth (TABM): We are […]
