2017: A Great Year for Spider Mites
Many areas in California have experienced a hot and dusty summer, perfect conditions that favor...
Spider mites can produce copious amounts of webbing. (Jack Kelly Clark)
Spiders, Spiders Everywhere
Here's one that I've never seen before. True spiders with webbing so heavy that it could interfere with the growing point of raspberry.
On approaching the field, once notices a lot of the very top of many raspberry plants in this field under tunnels with those leaves rolled up. Of course this sets off alarm bells that it could be LBAM, but closer inspection reveals a far heavier webbing than is customary for a leafroller. And... lots and lots of spiders.
What would the call be to do about this? Hard to say, readers if you have experience and/or suggestions what to do, write in and I'll post your answer.
