Thimet (Phorate) Applications

Thimet (Phorate) in the 10 percent granular form is being widely accepted in the South by seed orchard managers for insect control. This chemical, a systemic insecticide, is applied on the ground surface for absorbtion by the tree roots and translocation to all living tree tissues. Since Thimet is highly toxic to humans, extreme care must be used in its handling. For this reason the Virginia Division of Forestry designed and tested several new applicators for the safe handling and application of Thimet. The Division's Tree Improvement Program is rapidly expanding with more than 150 acres of loblolly pine seed orchard established to date. A goal of 300 acres will be reached within the next 2 years. In addition, a 30- acre white pine orchard and an 8-acre shortleaf pine orchard are already established, and a 10-acre Virginia pine orchard will be established in 1968. With all these seed orchard areas, insect control on the grafted trees is an absolute necessity.
