Vesicular Stomatitis Virus (VSV) has been confirmed in a horse in Tillman County, Oklahoma. This is a viral disease that is an economically important disease of cattle and horses but can infect all cloven hoofed animals. Learn more, here: okla.st/2KezvW4

Q: How do you manage flies and mosquitos around cattle and 🐴s to prevent the spread of diseases? 🤔 A: Find out below with Dr. Justin Talley, @okstate Cooperative Extension livestock entomologist. 📺: @SUNUPtv okla.st/2SEV1Wh

We encourage growers to inspect their fields once a week. When aphids are detected in a field, increase sampling to two times per week. Look at three consecutive plants and examine one upper and one lower 🌱on each plant. Read the @okstate e-pest alert: okla.st/2YryC4d

Home gardeners may be concerned that their plants are suffering from Ramorum blight or SOD. At this time, new rhododendron plants purchased at Home Depot or Walmart from February-June 2019 are the only effected. Read the @okstate e-pest alert, here: okla.st/2XVvPke

Make sure to join us for the Pecan Crop Loading Thinning Field Day! 📆: August 1 ⏰: 2:30 p.m. 📍: Cimarron Valley Research Station bit.ly/2LqGFrN

Heavy feeding by Potato Leafhoppers causes the entire alfalfa leaf to turn yellow and heavily infested fields take on a yellow color, even from a distance. Read the @okstate e-pest alert, here: bit.ly/2LCIJfU

Crapemyrtle bark scale diminishes the appearance of infested trees and shrubs by depositing honeydew on the branches and foliage, which encourages the growth of black sooty mold. Read the @okstate e-pest alert, here: bit.ly/2LxTxMh

Dr. Tom Royer, @okstate Cooperative Extension entomologist and IPM coordinator, has advice for producers as summer crops mature. 📺: @SUNUPtv bit.ly/2LAluTu

Most pecan insects should be reported as the number per nut cluster or per tree. In the early season, the pecan nut case-bearer should be reported as the number of eggs or larvae per 100 clusters. bit.ly/2X5Wtqe

Abundant rainfall has produced some high-quality 🍅 plants this year, and hornworms and pinworms will reap the rewards if you’re not monitoring for them. #GardenTips Learn more from this @okstate e-pest alert: bit.ly/2XoMNGM

A number of serious fungal, bacterial, nematode, and viral diseases are common to stone fruits and should be of concern to all growers. Learn more, below! ⬇️ bit.ly/2XKmWpN

Up until adult emergence in early June, intensive shallow cultivation of soil may destroy pupae. This is the only cultural management strategy for grape rootworm, & there are no known natural enemies that attack this pest. Read the @okstate e-pest alert: bit.ly/2XIpzIN

Grape rootworms were found in large numbers feeding on grape leaves. This insect pest had not been seen in the Perkins vineyard since June 2008, and the sheer number of adult beetles encountered was alarming. Read the full @okstate e-pest alert, here: bit.ly/2XIpzIN
