Why so little yellow shoulders in tomatoes this year? Normally at this time of year, I’d be writing about how bad yellow shoulders and other fruit ripening problems are in Maryland tomatoes. But this has been a strange season with May weather in March and March weather in May, which caused a great deal of catfacing problems this year.
Catfacing Problems in Tomatoes There have been some reports from growers and educators of several sets of tomato fruit with catfacing or that are deformed (Fig. 1). Catfacing results in fruit with deep indentations in the blossom end or fruit with significant distortions.  It is thought to be caused by a problem during the formation of the flower that results in the fruit not developing normally.
Potato Leaf Hoppers on Hops I do not usually look at hops very much as only a few farms have them, but they are becoming a bit more common in the last 10 years (Fig. 1). Visiting two farms withy hops I saw marginal leaf damage (Fig. 2) on some leaves (found some thrips too) and then marginal leaf scorch on others (Fig. 3).
Mites (Two Types) Found in Strawberries  While visiting some strawberry fields over the last few weeks, I ran into a few areas that had two spotted spider mite (TSSM) feeding. These were mostly in fields that had been using row cover. Spider mites Tetranychus urticae are well adapted to high-temperatures and can complete their life cycle in as little as 7 days when temperatures are > 80º F.
Allium (Onion) Leafminer The allium leafminer Phytomyza gymnostoma (also known as the onion leafminer) has recently been detected and confirmed from infested leeks in Lancaster County, PA.  This is the first confirmed infestation in the Western Hemisphere.
