on Plum and Cherry
The disease black knot is caused by a fungus. Black knot can occur on sweet and sour cherry, American, European, and Japanese varieties of cultivated plums and prunes as well as wild cherries and plums. The disease is common throughout much of Arkansas occurring on many wild plum and cherry trees. These serve as an annual source of infection for cultivated varieties.Black Knot

The pecan leaf phylloxera and the southern pecan leaf phylloxera feed primarily on the foliage, whereas the pecan phylloxera attacks the foliage, shoots and fruit and is therefore the most damaging (see image). The pecan phylloxera is a small, aphid-like insect that is rarely seen, but the galls it produces are prominent and easily noticed. Severe infestations can cause malformed, weakened shoots that finally die; such infestations can destroy entire limbs.Pesticide recommendations
INJECTION SITE MANAGEMENT
As cattle producers, we supply this nation with beef. Today’s consumer demands that our product is wholesome and free from blemishes. In order to meet this justified demand, we all need to be diligent in assuring quality in our final product. One very important factor in providing quality in the beef we produce is performing injections properly.
When injecting a medication or vaccine into a beef animal,remember to target the neck region. The landmarks outlining this region are noted in the injection zone triangle shown in Figure 1. Regardless of the animal’s age, all intramuscular and subcutaneous injections should be given in the neck region, never in the rump or back leg.
When injecting subcutaneously, remember to use the “tenting method” of injection shown in Figure 2. This method ensures that the product is delivered under the skin and keeps it out of the underlying muscle tissue.
