Pro Gibb prevents the development of chlorotic areas caused by black aphid feeding on the foliage. In the past we have advised using the 4% Pro Gibb material since heavy rates or application at the wrong time can lead to negative results for your trees. However, the 4% material is no longer made and Valent has replaced it with a 5.7% material. This formulation is safe to use on pecans and is labelled at the 5 oz rate. Based on Dr. Ted Cottrell&#8217;s work at USDA in Byron,\u00a0 the schedule for Pro\u00a0 Gibb applications should be as follows:<\/p>\n<p>Mid July: <strong><em>Pro Gibb 5.7%<\/em><\/strong> at <strong>5 oz\/acre<\/strong><\/p>\n<p>Early August: Pro Gibb 5.7% at 5 oz\/acre<\/p>\n<p>Mid August: Pro Gibb 5.7% at 5 oz\/acre<\/p>\n<p>Late August: Same as above <em><strong>if needed<\/strong><\/em><\/p>\n<p>Apply an aphicide along with Pro Gibb when black aphids reach threshold levels (15% of the terminals sampled have more than one black aphid adult with nymphs present on a compound\u00a0leaf) in August.<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Black aphid nymphs and feeding damage For those battling black aphids and considering using Pro Gibb to prevent the damage caused by this insect, applications should begin in mid July and continue for a total of 3-4 sprays.
