Lab Research Foliar application Tamarixia Continued from Page 33 Distribution optimization is the key. The goal there is to make sure the water is in the right place at the right time. Green said the soil type controls movement of the material and pore size dictates movement. Matching water delivery to the soil type will improve efficacy of the material applied. Green noted that regular maintenance and auditing of the water delivery system is important in micro and drip systems. ® The Grower’s Advantage Since 1982 Leonard supplied some of the basics for efficient use of imidacloprid delivered via irrigation. Admire systemic can be tank mixed with fertilizer, but needs agitation. In a 12 hour set, the product should be injected in a one to two hours period after the first three to four hours of the set to achieve the best distribution. It will take two to three weeks for the material to move up from the roots into the trees. The cooler the weather during that time, the longer it will take to move throughout the tree. The best strategy of use is to target the fall flush. Ventura coastal area growers have a more difficult time achieving success with this systemic application, Leonard said, due to the high clay and organic matter soils. If the material only reaches the sub lethal levels for ACP, it invites resistance. Comments about this article? We want to hear from you.
