Lots of moisture, humidity and these temperatures will mean a higher incidence of Disease in the Beets, Beans, & Corn.  Remember - the fungicides we have today are mainly for prevention of disease with some cure.  Early application is always the best!

The #1 corn insect pest is Corn Rootworm Larvae!  Larvae control is obtained two ways; either GMO Rootworm seed or Corn Rootworm Beetle Control at tassel time to prevent egg lying.  Both control options are needed!  GMO Rootworm corn is not enough due to resistance issues.  Spraying the beetles prior to egg lying is very economical.  Tank mixing with Headline Amp for plant health and disease control is my recommendation!  Call for more details.
