Data obtained from interviews with women from varying socioeconomic levels indicate that nutrition claims in ads do not attract attention as do colorful layout, appetizing food, or familiar people; that nutrition claims create a more favorable impression of a product; and that, depending on certain variables among respondents, knowledge of nutrition terms is often poor.

Because some of the newer, more effective rust fungicides had not been evaluated for control of rust of chrysanthemum, a study was undertaken to identify which chemicals are most effective against the disease. Zineb and chlorothalonil provided excellent control when sprayed before infection; oxycarboxin, applied through drip or tube irrigation systems, provided excellent control with less worker exposure and no visible residue.

Specific quantities of certain growth retardants, when applied foliarly in June or July, had a slight mitigating effect on symptoms of Verticillium wilt of cotton caused by Verticillium dahliae and increased yield of cotton 10 to 29 percent, whether it was grown on land infested by V. duhliue or not.

Plants grown on soils that have been fumigated with methyl bromide usually show increased bromide concentrations. While there is a potential health hazard involved, particularly where animals consume the forage grown, this can be minimized by choice of crop and by monitoring the accumulation of bromide by plants.

In tests conducted to determine the effects of ozone and pesticides acting together on foliage, methomyl and ozone interacted to produce greater injury than that produced by the sum of the two applied separately, whereas diazinon and ozone interacted to produce an antagonistic response (less injury than when applied separately). These complex interactions, and the varying effects of different amounts of the substances, suggest the need for future research.
