Re: Serratia info

Hi all,

I just want to make one more point, which might help to avoid some confusion to less experienced AG growers. The link below talks about a disease called "yellow vine". I'm sure it's quite valid and something to be aware of. But... AG's can have "yellow vines", that is, they are yellow in color, and very healthy. Some AG plants have vines that are yellow in color, some have green, and I've even seen some that are splotches of yellow and green in the same vine. These are healthy plants. 

So, be on the lookout for "yellow vine", the disease. But don't assume that if your plant has vines that are yellow in color, that they have a disease. Many of them have that color naturally.

-Cliff

Subject: Serratia info

Here is a link to my local extension's information on this disease where I copied the info from.  It is a form of yellow vine, spread by squash bugs (sort of the same way malaria is spread my mosquitoes). 

Plucking them off in the morning (as prevoiusly suggested) is the best method to fight them, epecially if you only have a few plants growing. It may seem like a large undetaking beacuse of the amount of stem and leaves present, but is the safest and most effective.  You have to get rid of the inscets early in the season - monitor daisly for them!  Once they start traveling from plant to plant is when the damage is seen.

Any chemicals will probably kill or hurt beneficial inscets, as well as possibly clog pores on the leaves, which the plant needs to thrive.  Besides, who wants to spray toxic chemicals on their babies?
