The difference between pre-treatment and post- treatment for control trees was used to establish the control achieved with Dinocide.ġ) The purpose of this study was to evaluate the control of Black Scale, Saissetia ole, using three different dose rates of Dinocide 2ml, 3ml and 4ml containing 12% Dinotefuran.Ģ) To observe and rate the performance of these treatments as to their effectiveness of action following a single application.ĭinotefuran, the active ingredient in Mauget’s Dinocide, is translaminar, which means that it can pass from a tree’s xylem (the layer in a tree that circulates water from the roots) to its phloem (the tree layer nearest the bark, which transports sugars from the plant’s leaves.) This capability makes Dinocide uniquely effective against pests.ĭinotefuran is an insecticide widely used on forest, woodland and ornamental trees and shrubs and is known for its speed of action. Adults, and immature adults where counted on stems and leaves for each sample and recorded.Ī pre-treatment sampling was taken Jprior to treatments (Table1).Ī sampling was takes on August 5, 2015, 61 days after treatment to determine insect control for each dose rate (Table 1). Random plots of Five trees per plot were selected each containing 1 control tree with no treatment administered per plot.įive trees per dose rate plus one control tree per plot were sampled.įive samples of 5 inch stem and leaf bunches per tree where cut, bagged and taken into the laboratory which set up on site where all samples were examined microscopically. approximately 1-2 miles from the Pacific Ocean with soft coastal influences.Īll trees were situated on a well irrigated golf course with several hundred California pepper trees scattered throughout the golf course in clusters and heavily infested with Black Scale. Old Ranch Country Club, Seal Beach, California. Trail results indicate significant mortality and reduced population levels of immature Black Scale, Saissetia oleae, following an application of trunk injected Dinocide of all three dosage treatments of Mauget’s Dinocide, while scale populations became higher in untreated control trees. Black scale is one of the damaging soft scale pests in California and can be found on numerous hosts including almond, apple, apricot, aspen, bay, citrus, cottonwood, coyote brush, fig, fuchsia, grape, holly, maple, oleander, olive, palm, peppertree, pistachio, plum, pomegranate, poplar, privet, prune, rose, and strawberry tree. The insect was introduced to California before 1880 and has since become an economic pest primarily on olive, but it can also cause damage on citrus. In North America, the insect is distributed in southern and western United States as well as in Mexico and Central America. location approximately 1-2 miles from the Pacific Ocean with soft coastal influences was micro-injected at root crown level approximately 6 inches above soil level with treatments of 2ml, 3ml and 4 ml Dinocide.īlack scale, Saissetia oleae, is a soft scale insect native to southern Africa that is currently an agricultural and horticultural pest in southern Europe, North America, South America, Asia, Australia, and New Zealand.
