minute 12:00 - lygus / tarnished plant bug
minute 13:12 - hoop house film and opacity

Wireworms - Chuck had positive experience planting a overcrop of flax to take care of wireworms that winter over in corn, fescue, and can effect potato crops. Symptoms of wireworm were described as wilting and dying plants of multiple families within two weeks. The stalks of the plants were cut open to find evidence of click beetle larvae.

Rust- Ann and Joern tried serenade, actinovate, and compost tea without much avail. Milky spore and nematodes were mentioned and discussed to fight rust. Clark from Lumpkin Co. extension mentioned the rust from surrounding pine trees should be a different species.

Nematodes: Chuck mentioned that the application of beneficial nematodes are crucial to their survival. Key things to note are that nematodes will drown easily. Use of a hose-end sprayer system may be the best way to apply and you need a lot! Sandy also noted there may be nematode eggs in worm castings.

Moles/Voles- Hildreth mentioned they may eat castor bean plant roots and die. Caution to be used with the toxicity of Castor Bean Plant.

Tarnished Plant Bug (Lygus) - Symptoms: irregularly-shaped, catfaced berries. The insects damage fruit by puncturing and then sucking the contents of individual seeds; which stops development of the berry in the area surrounding the feeding site. Ann mentioned they eat the stamina of the flowers. She said that Mycotrol, sticky traps and resistant varieties helped at their farm.

Hoop house plastic- Joern mentioned 55% opacity was not letting enough light in for berries. They are thinking of trying SolarIce Film (claiming 9 degrees cooler). Martine mentioned looking into SunMaster Films, a local company.

Spider mites- Ann mentioned they were able to control spider mites with ladybugs and beneficial mites

Worm Castings and compost tea- Sandy discussed achieving healthy plants and soil from using worm castings and compost tea. Also mentioning the book Teaming with Microbes by Jeff Lowenfels.
