weekly fruit and vegetable crop update 5-13-2014

Posted by Kyle Cecil -

1. 4 inch soil temp: 67.6 degrees F

2. Growing Degree Days (GDD):2014 = 130.0 GDD Average** = 95.0 GDD

3. The effectiveness of chlorine in produce wash water is affected by several factors. Clean, potable water should be used for wash water, and emptied when available chlorine gets low.  Organic matter debris and soil particles do adsorb chlorine, making it unavailable (do a pre-wash of harvested produce with potable water only before immersing in chlorinated water). Low pH (acidic water) also makes chlorine unavailable to disinfect. Water should be buffered to be neutral. High temperature causes volatilization of chlorine and it escapes into the air. ( Dr. James Thueri, U of I )

4. Effective aphid control depends on very thorough coverage of the insecticide  ... use enough water and pressure to get the insecticide spray to the parts of plants that are infested.  Click here for available products for control of this common pest in high tunnels.

5. Research farm update:  Horticulture Educator Chris Enroth, Commercial Ag Educator ( and Pathologist) Dr. Angie Peltier and I will be conducting a trial at the farm in Monmouth this year looking at no-till tomato and pepper production in crimped rye.  The rye is being crimped this week and the transplants should be going in ASAP.
