use them in any room where infants, the ill, or aged persons are confined. A 0.1- 

 percent pyrethrum 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 DHET (diethyltoluamide) ., 

 (6) For quick knockdown at cookouts, outdoor parties, or picnics, use either 0.1- 

 percent pyrethrum or 0.5-percent dichlorvos (DDVP) solution 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. 



Cereal product insects may be having lunch in your kitchen cabinets as uninvited house 

 guests. Many kinds of beetles and moths attack stored food products . They can be 

 found not only in packages or containers of food, but also in the cracks and crevices 

 in and around cabinets or cupboards. Follow these three simple steps: 



1. Remove all food packages from the cabinets and examine a small amount from suspect 

 packages under a bright light for signs of insects. 



2. Vacuum or carefully brush-out all cabinets and shelving. 



3. Spray the entire inside surface of the empty cabinets with a 0.5-percent diazinon 

 or 5.0-percent methoxychlor-oil solution from a pressurized spray can. 



WEEDS 

 DELAYED HERBICIDE APPLICATION 



How late after corn planting can you still apply a "preemergence" herbicide? This is 

 a common question, particularly because of the recent rains. If the weeds and corn 

 have not emerged and there is adequate moisture for herbicide activity (and there 

 probably is), most herbicides will still be effective. 



If the corn and weeds are just emerging, avoid using some of the herbicides with close 

 crop tolerances, such as Knoxweed, Londax, and Primaze. If the weeds and corn have 

 just emerged, consider rotary hoeing--where possible --along with a herbicide treatment. 

 The rotary hoe will control some of the emerging weeds; the incorporation will also 

 improve the effectiveness of the herbicide you use. 



If the grasses have emerged but have not reached the two-leaf stage, you can apply 

 Ramrod 65W (liquid form) and Ramrod/ atrazine as an early, postemergence treatment. 

 These treatments still require rain within 5 to 7 days for best results . 



If weeds are past the one- to two-leaf stage, consider an early, postemergence herbicide 

 treatment such as atrazine and oil. An AAtrex (atrazine) plus oil treatment is most 

 effective when the weeds (especially grasses) are no more than 1 to 2 inches tall. The 

 usual rate for grass control is 2-1/2 pounds, per acre of AAtrex SOW, plus 1 gallon of 

 special oil formulated for crop spraying. Occasionally, this treatment has injured 

 corn, under stress conditions such as excess moisture. 



The most-economical and effective postemergence treatment for most broadleaved weeds 

 in corn is 2,4-D. You can spray over the top until the corn is 8 inches high. On 

 taller corn, use drop nozzles (extensions) to keep the 2,4-D out of the corn whorls. 

 Be sure to apply no more than the recommended rate. For 2,4-D, that varies with the 

 formulation and the strength (the number of pounds per gallon) .
