Staying hydrated is important, especially during periods of physical activity and in warmer weather. With the availability of so many choices, making a decision about the type of water to drink can be challenging.
At the Penn State Fruit Research and Extension Center in Biglerville, Pennsylvania, apple scab spore release is declining but still active. Apple scab, cedar apple rust, and cherry leaf spot infection periods and predictions through May 24th are attached.
Dr Alan Lakso at Cornell University has developed a carbohydrate balance model for apple, which we are testing for predicting fruit set. This model estimates carbohydrate supply and demand, and then calculates the carbon balance of the trees. During times of high supply and low demand (sunny and cool), the balance is positive and it is difficult to thin chemically. When the balance is slightly negative (0 to -20°F), chemical thinning becomes easier. When the balance drops to the range of -40°, the trees are under significant carbohydrate stress, and chemical thinning will be strong. Below -40°, the natural stress may be so severe that some fruits will be shed even when thinners aren’t used. Below -40° the response to chemical thinners is predicted to be very strong.
On May 16, 2011 the U.S. Environmental Protection Agency (EPA) announced improvements to the availability and usability of drinking water data in the Enforcement and Compliance History Online (ECHO) tool.
The insect pest control updates presented here are for the south-central part of Pennsylvania based on observations in Adams County, Pennsylvania. It is important to modify your integrated pest management practices based on scouting of your own orchard blocks.

Are you a new grower? Do you know what temperature is best for seed germination and maintaining healthy seedlings? I find that these and other tidbits about seed and seedling biology are extremely helpful for growing healthy seedlings in the greenhouse. By now, many of your seedlings are out in the field, but it's a good time to look back over what went right, and what went less than perfect in the greenhouse and make some notes for next year. Take a look at the following information and new factsheets for new organic vegetable growers.

Fruit growers report that this has been a challenging spring in terms of applying cover sprays, and now chemical thinners. Fortunately, a number of varieties were thinned last week when the temperature range was favorable. However, fruit size of some varieties was too small last week and these may still need to be thinned.
It is not unusual for Pennsylvania to experience plenty of April showers but this year was exceptionally wet. Some areas of Pennsylvania set new records for April rainfall.
Some of you have contacted me wondering if we are still in the primary apple scab stage. There have been reports indicating that primary scab is over in neighboring states and it has also been suggested that ascospore maturation would progress much faster, and therefore terminate early in the kind of weather we are experiencing this spring. To clarify, today we counted ascospores in numbers that far exceed our monitoring threshold so we are still in the primary apple scab phase of the disease. Also, we observed the first fruits with apple scab symptoms on nontreated trees here at the Penn State Fruit Research and Extension Center this morning.
Dr. Greg Krawczyk and Dr. Larry Hull, entomologists at the Penn State Fruit Research and Extension Center in Biglerville, will be posting insect pest control updates, or "Insect Bytes" each Friday. The updates are based on observations in Adams County, Pennsylvania, and it is important to adjust the recommendations for your specific orchard conditions.
