    ...Another hot week before a trend toward normal...

    This week will be marked by hot and humid conditions with rains later Tuesday into Wednesday from the remnants of Barry. Most places will likely see 0.50-1.00 inches but even with Barry going by the rainfall will be highly variable with some areas getting less than 0.50 inches and others getting over 2.00 inches.

    Spray drift not only results in wasting expensive pesticides and pollution of the environment, it may damage non-target crops nearby, and poses a serious health risk to people living in areas where drift is occurring. Drift happens! It accounts for about half of all non-compliance cases investigated by the Ohio Department of Agriculture.

    Two new factsheets summarizing key components of the work to update the Tri-State Fertilizer Recommendations are now available.

    Updated Grain Nutrient Removal Rates

    How many pounds of nutrients are removed with every bushel of corn, soybean and wheat harvested? This factsheet reports new numbers and shows how nutrient removal rates in harvested grain have decreased over the past 25 years.

    This year, due of the wet conditions we experienced during the spring, Fusarium head blight, also known as head scab, developed in a few localized areas of the state. Grain harvested from scab-affected fields is often contaminated with vomitoxin and other mycotoxins, because the disease and toxins go hand in hand. Severely affected kernels are usually small, shriveled, lightweight, covered with pinkish-white fungal mycelium, and most importantly, heavily contaminated with mycotoxins.

    Corn development varies tremendously across Ohio because of planting dates that range from late April to early July. Some corn is tasseling and silking but in many counties, corn stages range from V7-V12. Moreover, it is not unusual to see striking differences in plant height and growth within cornfields.

    It is important to understand corn growth and development in order to determine the health and status of the crop for effective use of management practices (e.g. application of post-emergence chemicals) and assessment of stress events (e.g. flooding, drought, hail, etc.).

    Waterhemp and Palmer amaranth are both now listed on the Ohio noxious weed law, which means that landowners must take steps to control infestations and prevent further spread.  Since these are annual weeds, preventing spread is achieved by preventing plants from reaching maturity and producing seed.  This is the basis for our “No pigweed left behind” effort, for which the goal is to create an understanding that the only way to beat these weeds is to prevent seed.  Prevention needs to occur in any area that might be subject to infestation, such as roadsides, parks, conservation seedings, par

    Week three of The Ohio State University Western bean cutworm (WBC) monitoring network has resulted in an increase of moths captured. Last week’s trap count included WBC adults captured from July 8 – July 13. A total of 24 counties monitored 75 traps across Ohio. Overall, trap counts increased, resulting in a total of 287 WBC adults (18 total last week) and a statewide average of 3.8 moths/trap (up from 0.3 average last week) (Figure 1).
