Entomology Updates

The 2019 Mid-Atlantic Commercial Vegetable Recommendations guide is now available! A couple of corrections have come to my attention that you should be aware of. The first is that Vydate L is incorrectly listed in the Potato chapter. The correct formulation is Vydate CLV; Vydate L was introduced in 2018 and does not have potato on its label. It has a much lower % active ingredient than Vydate CLV. If accidentally applying Vydate CLV with the Vydate L use rate, you will apply more than a 2x rate of active ingredient! As always, pay attention to formulations and labels on products!

Several lambda-cyhalothrin containing products in the Sweet Corn chapter have an incorrect PHI listed. The PHI for Warrior, Besiege, and Lambda-Cy is 1 d PHI; the product Cobalt Advanced is a 21 d PHI as listed in the guide.

I’ve also shared the Handy Bt trait table for field corn with you before, you can find a link to it here: https://lubbock.tamu.edu/files/2018/11/BtTraitTableNov2018.pdf. At some of the recent winter meetings, I have mentioned a couple of soil insect pest sampling techniques. There’s a great 50 second video for baiting wireworms by Purdue that can be found here: https://www.youtube.com/watch?v=t3VUKw_TfKc.

For those of you wanting to know more about spotted lanternfly, the NE IPM Center will have a series of webinars focused for the hops, berry, and vegetable grower, the grape and tree fruit grower, Christmas tree growers, and the ornamental industry. See the announcement in this WCU for more information.
