Mealybug Focused Project Sites - Alternatives to Organophosphates
Zabala. This site is being use to evaluate several biological control agents. Both mealybug destroyers and green lacewings have been released here. Due to the high presence of Argentine Ants at this site, both the mealybug destroyers and green lacewings have had difficulty establishing.
Cal Poly. This site has an established population of Obscure mealybugs on them. CCVT staff is using this site to evaluate biological control agents and reduced risk materials. This site has a well established population of Argentine Ants at this site making the establishment of biological control agents difficult.
Paragon. This site is going to be used to track the potential movement of some high risk materials in surface water runoff during simulated storm events, A rain simulator is being used to generate rainfall in a controlled experiment to try and quantify the potential movement.
Weed Focused Project Sites - Alternatives to Simazine
Sunnybrook. There are five under row weed control methods being investigated at this site. Weekly weed population samples are being taken at this site. As well as weed populations, insect populations are also being evaluated in association with each treatment. The effect of the treatments on vine growth, grape and wine quality will also be evaluated.
Hog Canyon. Two pre-emergent herbicides are being evaluated at this site. Weed populations are evaluated on a bi-weekly basis. Effect of treatments on vine growth is measured late in the season, and effect on yield is measured at harvest.
Chalk Knoll. Three weed control practices are being tested at this site. Two pre-emergent herbicides and cultivation practices are being looked at for their effectiveness on weed control. Measurements are taken on a bi-weekly basis. Vine growth and yield are measured late in the growing season.
