Spittlebugs have been hatching for some time now. Control with insecticides has not 

 been profitable for several years. However, if there is more than one spittlebug 

 nymph per stem , treatment may be justified. Use 1/2 pound of methoxychlor per acre 

 at least one week before harvest. 



CORN 



) 



Flea beetles will pounce on corn as soon as it emerges , particularly in southern 

 Illinois. The winter may have been severe enough to kill some of them, but the snow 

 cover may also have protected them. These small, black beetles jump when disturbed 

 and are difficult to find on corn leaves, since they leave the corn before you get to 

 the plant. They eat or strip the green from the plant leaf- -leaving tiny, white, 

 elongated scratch marks on the leaves. Damaged plants will generally turn silvery, 

 then brown. If enough plants are being killed to warrant the cost of insecticides, 

 apply 3/4 pound carbaryl (Sevin) or 1-1/2 pounds of toxaphene per acre, as a hand 

 spray over the row. 



Slender seed-corn beetles are active throughout the state. The phosphate insecticides 

 [diazinon, dasanit, Dyfonate, and phorate (Thimet)] --applied as a 7-inch band ahead 

 of the press wheel- -will control them. Diazinon seed-treater will also prevent seed 

 and seedling damage. 



European corn-borer pupation reached the 50-percent level this week- -as reported by 

 Earl Lutz, the Gallatin County Extension Adviser, at Ridgway. Further north, pupation 

 is well underway. Emergence in northern Illinois should be underway in 2 to 3 weeks, 

 depending on the temeprature. Not much corn will be susceptible to first-generation 

 damage . 



HOMEOWNER 



You can prevent ants, water bugs, spiders, crickets, and other insects from entering 

 your home by spraying the outside foundation wall with a 2-percent chlordane water 

 emulsion. Purchase chlordane as a liquid concentrate and mix it with water to the 

 proper strength (1 pint of 45-percent chlordane in 3 gallons of water gives a 2-percent 

 solution) . Spray the foundation wall from the soil to the sill area, or along the outer 

 wall for a distance of about a foot above the soil to the point of runoff. In addition, 

 spray 5 to 4 inches of soil adjacent to the wall and the expansion joints along porches 

 and steps, plus the edges of walks. In homes with a crawl space, spray the inside wall 

 of the foundation and any supporting pillars. Do not spray shrubbery or flowers, be- 

 cause the oil in the spray may burn the tender foliage. 



Three gallons of finished spray should do for the average house. The need for using 

 insecticides inside the home will be greatly reduced by using this type of treatment. 



Ticks are annoying campers, picnickers, hikers, fishermen, and other persons. They 

 cling to the vegetation along paths in and near wooded areas, waiting for man or other 

 warm-blooded animals to come along. They attach themselves by embedding their mouth- 

 parts into the skin. When entering wooded areas or ones suspected of being tick-infestei, 

 use a repellent on socks, pants, pants cuffs, and exposed parts of the body to prevent 

 tick bites. DEET (diethyltoluamide) is one of the best tick repellents. To control 

 ticks in the home yard as well as in parks or playground areas, spray the grass, shrubs, 

 and flowers with diazinon, malathion, or carbaryl (Sevin). Do not apply diazinon to 

 ferns or hibiscus, malathion to Cannaert red cedar, or carbaryl to Boston ivy. 



There are scattered reports of eastern tent-caterpillar infestations. These insects 

 form nests of webbing in the crotches of tree limbs --especially wild cherry, willow,
