Sod webworm larvae were reported damaging a few lawns. These were probably larvae that 

 overwintered in the soil and have just recently moved to the surface to feed. Only 

 occasionally are overwintering larvae numerous enough to cause damage. Actually, not 

 even the first-generation webworm larvae in June and July present the major problem; 

 rather, the second-generation ones in August. 



Carbaryl (Sevin) , diazinon, or trichlorfon (Dylox) as sprays or granules are effective 

 against sod webworms. Follow the instructions on the label relating to dosage, method 

 of application, and precautions. 



Crayfish . We were asked what to do about crayfish in low- lying lawn areas where rains 

 have been heavy. Our first thought was to stock the lawns with large-mouth bass, if 

 conditions are still wet enough; otherwise, wait until conditions dry. The crayfish 

 will disappear then. 



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 as tick- infested, 

 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. 



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 outside, 

 preventative treatment. 



WEEDS 

 INCORPORATING SOYBEAN HERBICIDES 



Most people incorporate herbicides to reduce the surface loss of volatile herbicides. 

 Treflan, Planavin, and Vernam are all subject to some surface loss when left exposed 

 on the soil surface. Label recommendations for these herbicides have changed during 

 the past year. 



Previously, the manufacturer of Treflan suggested that it be incorporated immediately. 

 The current recommendation is that incorporation can be delayed as much as four hours 

 after application. Weed control may be variable because of delayed incorporation- -if 

 the application is made to wet, warm soil or if the wind velocity is 10 m.p.h. or greater.
