Friends of mine that I gave a plant to asked me to take a look at a problem with one of their plants. They said the leaves were yellowing on just one vine. I thought maybe an SVB. I decided to go take a look at it. No SVB, but I've never had this problem. The leaves have turned bright mustard yellow. They said its happened over the course of two or three days. Other than the leaves being yellow the plant doesn't show any signs of problems. The leaves aren't wilting and their small pumpkin that was just pollinated last week hasn't aborted. I got a pic and posted it in my diary again. What would cause this? We've had lots of rain and humidity lately but cool temps. They've been fertilizing once a week with a 20-14-13 water soluble fert. I told them to stop using the fert, that maybe its a soil imbalance issue or possibly a disease. Any ideas?

Speaking of darn svbs I thought I had them kicked but I guess not. Ive been picking their eggs off every day in the last couple of days I havent found any eggs so I though it was over. I came home yesterday and seen a wilted leaf by the stump. I looked at one of the back vines of the stump and cut into it. There was my first worm so I removed that vine. I checked the rest of the vines I didnt see anything else hopefully I only have to kill that one vine. Is there any chance my plant will survive and does anyone think its a possibility the svbs are gone for the season??

Some you loose, some just get huge gnarly looking scars... Just paint your Daconil on and keep watching it.

Hi Jason,
Is it just one egg in each spot or is it a cluster of eggs?
Do you have a picture of one of the squash vine borers?
Thanks,
Doug

JeffL, Yours looks similar but with the edge burn and patchy spots could also be spider mites....Check underneath the leaves and see if you find a crystalization....Put a piece of paper under the leaves, tap on the top sides of the leaves to dislodge and knock down onto the paper, try to smear the dots and debri...if they smear then its mites....some are so small, this is the only way to tell as it appears like tiny specs of dirt on the paper but are not, some are big enough to see crawling around with their tiny webs too. I sprayed last night for mine, Bayer Tree and Shrub for systemic, and Orthomax for contact under the leaves....I used 2 OZ in 5 gallons of water...I hate mites. It appears I moved them from one patch to another patch with my shoes.....Next year we hit it with Tree & Shrub before we plant. Hope this helps and I also would look for Steve Tremors advice.

Hey doug I wish I had a picture. There are a couple differnt kinds of borers. The most typical one will usually just leave a little reddish brown egg on the undersides of leaves scattered and some times on the stems. Another kind which is easier to spot are a shiny gold egg which you will find clumped togeteher. Theres also some that leave yellowish eggs clumped together. The ones that are hardest to find are the reddish orange ones. I dont have a picture but usually in the heat of the day youll see a bug that apears to look like a black wasp. But if you see it up close it actually resembles a moth and has a distinctive red marking on his back. There tricky to catch as theyll fly drunken all around your plants usually low and slow. If you see this bug watch out its a tough battle one unfortunetly im losing im afraid. The actual bug isnt the problem but the grubs that hatch from the eggs are. They will immediatly find a place to enter and borer on it. I thought it was over but like I said I found the grubs. A couple were already dead from chewing through the sprays, but they can do damage real quick. Your plants will look like they havent been watered in 100 days wilted to the ground. Be on the lookout Doug their in Georgia and still here im afraid.

I have sprayed my plants a lot with my Stihl mister. I don't see how anything could survive on my plants. With that said I'll check on the mites. Thanks
