Potato spraying in eastern Virginia in 1937

ConclusionsAs shown by these results spraying potatoes with a calcium arsenate-Bordeaux mixture gave significant increases in yield when potato flea-beetles or potato leafhoppers were present in injurious numbers, and did not give significant differences in yield when these pests were not present to an injurious extent.

Desilking Sweet Corn to Control Corn Ear Worms, and Notes on Control of Fall Armyworms

The corn ear worm, Heliothis obsoleta (F.), has been such a serious pest of sweet corn in southeastern Virginia that very few people attempt to grow this crop in this area. Carruth (1936), Pepper (1937), Ridgeway (1938) and Barber (1938) have reported varying degrees of success in controlling the corn ear worm on sweet corn by removing the silks at about 3-day intervals during the silking period. In the spring of 1938, it was decided to try this method of control on four varieties of sweet corn planted on three different dates at Norfolk, Va. The varieties used were Marcross C 3, an early developing sweet corn, Golden Cross Bantam, Money Maker and Stowells Evergreen. Plantings were made on April 21, May 23, and during the first week in July.

Control of Truck Crop Aphids

The control of truck crop aphids is a difficult problem which often varies with the species of aphid and type of crop attacked. From the published reports of many workers, it seems that no treatment gives entirely satisfactory results in all parts of the United States or even in one community under varied weather conditions. This paper is a summary of the results of experiments conducted at the Virginia Truck Experiment Station for the control of several species of truck crop aphids and of methods used by truck crop growers for the control of these pests in Tidewater, Virginia.
