Buy chlordane as a liquid emulsion concentrate and dilute it with water to the 

 proper strength (1 pint of 45-percent chlordane liquid concentrate in 3 gallons 

 of water gives a 2-percent solution) . Spray the foundation from the sill to the 

 soil until the spray runs off. Also, spray 2 to 3 inches of soil next to the 

 foundation wall. Spray in cracks or expansion joints, along porches and around 

 steps, also along the edges of sidewalks and driveways. In houses with crawl 

 spaces, treat the inside of the foundation wall, as well as the outside, and 

 spray support pillars. The average house requires about 3 gallons of finished 

 spray. Do not spray near wells or cisterns. Do not spray shrubbery or flowers, 

 because the oil may burn the foliage. Repeat the treatment in late summer for 

 protection in the fall. 



If you have noticed a sticky substance on the leaves of trees, shrubs, or flowers, 

 chances are that aphids are present. Cars parked beneath infested trees become 

 covered with these sticky spots. These small, green, black or red, soft -bodied 

 sucking insects secrete a sticky substance called "honeydew." White specks are 

 usually visible on the leaves; these are the cast-off skins of the aphids. Ants 

 are often attracted to the sugary material, and an abundance of ants on plants 

 may indicate aphids. The leaves of heavily infested plants will curl, yellow, 

 and turn brown. Damage is accentuated when soil moisture is low. For control, 

 spray foliage thoroughly, using 2 teaspoons of 50- to 57 -percent malathion or 

 25-percent diazinon emulsion concentrate per gallon of water. Do not use mala- 

 thion on African violets or cannaert red cedar. Do not use diazinon on ferns or 

 hibiscus . 



Tomato hornworms and tomato fruitworms (corn earworm) are attacking tomatoes in 

 the southern half of the state. Spray with carbaryl (Sevin) , using 2 tablespoons 

 of 50 -percent wettable powder per gallon of water. Repeat the treatment every 

 week if worms persist. There is no waiting period between treatment and harvest. 



Mosquito populations continue to be high in many areas. This is fast becoming a 

 record year for this insect, probably as a result of the wet weather during May 

 and June. 



To reduce the number of mosquitoes, follow these steps: (1) Eliminate standing 

 water in such places as eave troughs, old tires, tin cans, childrens' toys, storm 

 sewers, etc. (2) Apply a water-base spray containing 1-percent malathion (2 ounces 

 of 50- to 57 -percent liquid emulsion concentrate per gallon of water) to shrubbery 

 and tall grass. Repeat the treatment every week or two if needed. (3) Keep the 

 screens on doors and windows in good repair. (4) Hang plastic resin strips (2" x 

 10") containing 20-percent dichlorvos (DDVT)--one strip per 1,000 cubic feet of 

 space, or about one per room. These strips will kill mosquitoes and flies for 4 

 to 6 weeks. As an added precaution, hang the strips where children can't reach 

 them and away from fish bowls and food counters. A 0.1-percent pyrethrin space 

 spray- -applied from a pressurized spray can- -can be used for quick knockdown in 

 place of the dichlorvos resin strips. Frequent treatments will be needed during 

 problem periods. (5) When entering mosquito- infested areas, use a repellent. One 

 of the most effective mosquito repellents is DEET (diethyltoluamide) . (6) For 

 quick knockdown at cookouts, outdoor parties, or picnics, use either 0.1 -percent 

 pyrethrin or 0.5-to-l percent dichlorvos (DDVP) as an oil- or water-base space 

 spray. Spray the mist lightly beneath tables and chairs and into the air for a 

 few feet around the area. Repeat the treatment as needed.
