Scouting, prevention and control of the iris borer.

This insect is the most serious insect pest of iris in Nebraska and is found virtually everywhere in the state. Damage is characterized by dark, streaked, or watery areas and ragged edges on the developing leaves of iris in May and June and extensive destruction of the insides of the rhizomes in July and early August. Examination late in summer will reveal a large white to pinkish caterpillar from 1 1/2 to 2 inches long in the rhizome, usually accompanied by a foul-smelling soft rot.

Nutritional quality control begins with knowing and adjusting for variation in the moisture content of feed ingredients. Moisture variations in feeds are almost always of more importance than variations in protein, mineral, and energy. Inventory control is affected by moisture content of feeds. Some feeds on hand are constantly changing in moisture content, and these changes frequently lead to financial losses when a price adjustment is not made for moisture losses.

G73-62 Webworm Control In Sugarbeets (Revised March 1979), Arthur F. Hagen

Historical Materials from University of Nebraska-Lincoln Extension

The sugarbeet webworm and the alfalfa webworm attack sugarbeets. Frequent outbreaks have been reported in sugarbeets from both species, so they are now generally listed only as "webworms." Their life history, damage and control are similar and are discussed in this publication.


G73-61 Pale Striped Flea Beetle In Sugarbeets And Beans (Revised March 1979), Arthur F. Hagen Jan 1973

G73-61 Pale Striped Flea Beetle In Sugarbeets And Beans (Revised March 1979), Arthur F. Hagen

Historical Materials from University of Nebraska-Lincoln Extension

Only small areas of western Nebraska appear to be troubled by this insect at present, but it appears to be infesting larger areas of sugarbeets each year.

This publication discusses the life history, damage and control of the pale striped flea beetle in sugarbeets and beans.
