    It’s always amazing to see apparently still thriving winter annual weeds underneath the snow or following some really cold weather.  Even the dandelions in the lawn appeared healthy yesterday, although they can be one of the first weeds to turn purple following really cold weather.  Their healthy appearance and lack of symptomology is actually somewhat disturbing since I treated them just prior to the recent deep freeze and had higher expectations.  Our best advice at this point on

    From many of the samples we recovered both Pythium spp. and Fusarium spp..  Both are well-known seedling pathogens.  Our next step was to examine what the Pythium spp. were and then to determine if these were sensitive to metalaxyl.  In approximately 60% of the locations we were able to obtain a good quality sequence and a metalaxyl test for 28 isolates.

    Modified Relay Intercropping (MRI) is the planting of soybeans into headed wheat that may occur up to 6 weeks or more prior to wheat harvest; whereas Double Cropping (DC) is the planting of soybeans after wheat harvest.    Vyn et al, found that relay intercropping of soybeans yielded better than double cropping of soybeans north of I - 70 in Indiana (
