Insecticide choice Soybeans usually are not damaged by potato leafhopper, but the breeding line on the right was very sensitive to potato leafhopper feeding in an MSU trial. Threebanded leafhopper, Erythroneura tricincta, and Virginia creeper leafhopper, Erythroneura ziczac, can both be found in eastern U.S. vineyards. Adults are yellowish green with a long, wedge-shaped body. Feeding is concentrated on young tissues near the shoot tips. As leafhopper feeding continues, the plants become stunted. While feeding, potato leafhoppers inject a watery saliva that includes an enzyme that reduces plant photosynthate movement. Yield loss occurs through reductions in intermodal length and stem height, and decreases in crude protein content. Most surviving adults will leave the field. Sample 35 leaves, three to five times in the field. Determining the need for leafhopper control: Some late instar nymphs have been observed and this is the time populations may, or may not, get rolling. Pest description and crop damage The most important leafhopper for potato producers in the PNW is the beet leafhopper, due to its ability to transmit the beet leafhopper transmitted virescence agent (BLTVA) phytoplasma. 1993, Foster and Flood 1995).

The adult potato leafhopper is pale to bright green and about 1/8 inch long. Because of this, stubble sprays are unnecessary. This means you should confirm that potato leafhoppers are still active in a field with hopper burn before making an insecticide application. Potato leafhopper can arrive in Ontario as early as May. Their hind legs are modified for jumping, and are covered with hairs that facilitate the spreading of a secretion over their bodies that acts as a water repellent and carrier of pheromones. For most of this time, control of leafhoppers has involved periodic insecticide applications to prevent excessive yield loss. Above 1 pt, no grazing or harvest for 21 days. Potato leafhopper density was determined from sweep samples on that same date before the foliar sprays were applied. A phytoplasma infection rate of 2% in leafhoppers was recommended as a standard to trigger insecticide treatments for the aster leafhopper in the Midwest (Mahr et al. The potato leafhopper does not overwinter north of the Gulf states. See Doane's Agricultural Reports "greenbook" at:  http://www.greenbook.net or other resources for additional registrations. Insecticides are the only effective therapeutic tool for reducing potato leafhopper populations that have exceeded the economic threshold. A leafhopper is the common name for any species from the family Cicadellidae.These minute insects, colloquially known as hoppers, are plant feeders that suck plant sap from grass, shrubs, or trees. There are five nymphal stages, with the fourth and fifth stages having noticeable wing pads. Preharvest interval 7 days after ½ pt, 14 days after 1 pt. The nymphal stages closely resemble the adult except that they are smaller, wingless, and more yellow in color. Scouting Notes Leafhoppers migrate into potatoes in early summer after alfalfa is cut. Among potato varieties, there are dramatic differences is susceptibility to hopperburn (or attractiveness to the potato leafhopper). Potato leafhoppers can be very destructive on hybrid or vinifera varieties that are sensitive to the saliva they inject while feeding. They are more commonly referred to as the potato leafhopper. Photos A-D. Leafhopper adults (1/4 inch long) are slender, wedge-shaped insects that fly or disperse rapidly when disturbed. Some parts of this site work best with JavaScript enabled. The immature forms, or nymphs, are pale green and wingless. In North America they are a serious agricultural pest. Insecticide sprays directed at the potato leafhopper, Empoasca fabae (Harris), conflict with the life cycle of Microctonus aethiopoides Loan, a parasite of the alfalfa weevil Hypera postica (Gyllenhal). MSU is an affirmative-action, equal-opportunity employer. Compute the number of leafhoppers per sweep and use the "Potato Leafhopper Economic Threshold Table" below to determine if control measures are needed. Be careful when opening the net; adult leafhoppers are very active and can easily escape without being noticed. This list is not inclusive. Empoasca fabae belongs to family Cicadellidae and genus Empoasca within order Hemiptera. Attacks apple as well as many agronomic crops. Sustainable Agriculture — Monitoring fields for populations and correctly identifying the leafhopper is essential to good management. Harvesting will kill a high percentage of potato leafhopper nymphs and some adults. Nevertheless, we do want to prevent severe hopper burn. DAMAGE DONE: Once damage is done by potato leafhopper, early harvest or insecticide application are the only two options available. When necessary, apply a selective insecticide against immature stages. (Photo by Chris DiFonzo, MSU) Monitor the population by examining leaf undersides, especially on younger trees.
