Evaluation of phorate and Di-Syston for potato insect control in New York

The systemic insecticides phorate and Di-Syston were applied at varying rates in bands in the row at planting time. Phorate gave good flea beetle control throughout the season during two years of the three that the experiments were conducted. Di-Syston was less effective.

A Physiological Response of Potato to Foliar Applications of the Insecticide, Guthion

Use of the phosphate triazine insecticide, Guthion® ( O, O -dimethyl S -4-oxo-1, 2,3-benzotriazin-3-(4H)-ylmethyl phosphorodithioate) as a foliar spray for potato insect control has resulted in increased yields of red-skinned potatoes above that normally obtained as a result of efficient insect and disease control. The magnitude of this increase averaged about 15% and was solely attributable to increases in set of tubers. Dry matter and potato grade based on size was not affected. While tuber set of white-skinned potatoes was also increased slightly, results were not significant, and yields were less than those obtained from other plots treated with insecticides.

Use of certain new materials in the control of potato insects in Michigan

In the spraying and dusting experiments at the Lake City Experiment Station during 1947 insect infestation was not a serious problem. Most consistent control of potato insects in general was accomplished by applications of DDT in either sprays or dusts. Of the new materials used, Parathion 3422 as a dust was the most promising particularly in the control of the potato leafhoppers, whereas applications of 5 per cent DDT gave almost complete control of the six-spotted leafhoppers, flea beetles, and tarnished plant bugs. Benzene hexachloride, as a dust, ranked with DDT in the control of tarnished plant bugs and flea beetles. In the control of leafhoppers, however, benzene hexachloride in dust or spray combinations was not as effective as DDT. No late blight was present. There were no significant differences between materials in the control of early blight, because of the early killing frost.

The use of new insecticides in the control of potato insects

In spraying and dusting experiments carried on at the Lake City, Michigan Experiment Station, potato leafhoppers, 6-spotted leafhoppers, spittle insects, and tarnished plant bugs were abundant throughout the growing season of 1946.

Promising new insecticides for control of potato insects in Western Washington

Dusts containing DDT, DDD, DMT or benzene hexachloride in mixture with CAC (Copper A Compound) fungicide were superior to standard calcium arsenate mixture for the control of flea beetles and aphids in 1946 at Arlington, Washington. However, tuber infestation by flea beetle larvae was greater in plots treated with the DMT-CAC mixture than in plots treated with any other combination of materials.
