Bt and Herbicide Tolerant Traits in Corn and Current Resistance of Target Insect Pests
Listed below are the corn trait packages to make it easier to understand seed guides, sales material and bag tags. It is an abbreviated version of the Bt trait table plus related extension materials free online at: https://www.texasinsects.org/bt-corn-trait-table.html. Information listed Includes the name of each trait package, bag tag code, Bt toxins expressed (Cry1 types and Vip3A for caterpillars, Cry3 types for rootworms), refuge requirement (RIB=% refuge in the bag or REF=% structured refuge) and herbicide tolerance (GLY= glyphosate /Roundup-Ready, LL=glufosinate/Liberty Link, 2,4D or group 1 ‘fops’ type herbicides). Note that older trait packages, with limited or no commercial availability, are listed, so you can look back and interpret previous year’s planting records, seed guides, and research results.

Fusarium Crown Rot in Squash
A County agent sent pictures of squash that were turning yellow and wilting (fig. 1). This was found to be Fusarium crown rot caused by the fungus Fusarium solani f. sp. cucurbitae with a little Anthracnose caused by Colletotrichum orbiculare mixed in with it. In the field, Fusarium crown rot is generally a problem in summer and winter squash, and some pumpkin cultivars, but most cucurbits have been found to be susceptible.

Summary of the Comparative Efficacy of Common Active Ingredients in Organic Insecticides Against Difficult to Control Insect Pests
There exists a lack of control efficacy information to enable decision-making about which organic insecticide product works best for a given insect pest. Here we summarize results of 153 field trials on the control efficacy of common active ingredients in organic insecticides against groups of the most difficult to control insect pests. The performance of organic products Entrust (spinosad), Azera (pyrethrin and azadirachtin), PyGanic (pyrethrin) and Neemix (azadirachtin) varied widely among pest groups, as well as among pest species within a group, providing an overall reduction in pest infestations by 73.9%, 61.7%, 48.6% and 46.1%, respectively.

Early-Season Scouting For Wheat Diseases
Spring is a busy time on the farm that demands a lot of different tasks; one of the tasks that can be overlooked is scouting your small grains now for the presence of diseases, especially this year considering many areas of the state are off to a wet start. For a few select diseases, scouting now could pay off later in the season.
