Organic try neem oil mix with liquid antibacterial soap to help it stick this has been a great item for me 15+ years kills all stages of bugs.bacteria
Also controls fungicide and bacteria includes black spot...rust...scab...powdery mildew...Botrytis...some blight....alternaria....Downey mildew.....leaf spot.....go by directions on bottlebecause ginseng plants are in a shaded environment you can use a little bit more liquid concentrate because it's not exposed to extreme sunlight it won't hurt to the plant leaves
Usually mom and pop hardware stores have it ..worst case check ebay sellers carry a 70% i believe $15 a bottle works good mix a little dish soap to get the oil to stick and use warm water I don't like it for full sun plants but ginseng being shaded is perfect
Whitjr, Sysbee is right. You will be able to find it in pint containers in small stores. Around 10 bucks. Funky smelling stuff. My wife and I use it on our farm in FL. It doesn't work good on hard shelled bugs. Like stink bugs and potatoe beetles. Good product though on other issues like Sysbee said.
Those things will eat almost any plant that has a relatively soft stem and produces a berry or fruit. Yesterday I spent about 3 hours in the woods looking for them, it only took about 5 minutes for me to find some, the first ones that I found were nestled on my false unicorn plants, the next ones I found were at the Base of some goldenseal berries, and they were also present on my ginseng, my bloodroot has already dispersed their seed,so none was found there, I think that bloodroot may be relatively safe from these critters do to their early seed development. I continued to look and found them on mayapple plants,wild blackberry plants. Just out of couriosity I checked some Virginia creeper and found some on there as well, In growing wild simulated ginseng you are out of luck on pesticides but there are natural ways to combat these bugs, think about the food chain what would like to munch on these creatures? Spiders,praying mantis and the great aphid slayer...the common lady bug.
