Effect of acidification of insecticide sprays in pest control of sugar beet seedlings
The pH of dimethoate, formetanate and methidathion insecticide spray liquids was reduced from 8.0 to 4.0 by adding 0.1 M H3PO4. Acidification did not improve the effectiveness of sprays against Lygus rugulipennis, Chaetocnema concinna or Piesma maculatum. There were also no significant differences i...

| Summary: | The pH of dimethoate, formetanate and methidathion insecticide spray liquids was reduced from 8.0 to 4.0 by adding 0.1 M H3PO4. Acidification did not improve the effectiveness of sprays against Lygus rugulipennis, Chaetocnema concinna or Piesma maculatum. There were also no significant differences in root or top yields between plots treated with acidified insecticides and the incecticides alone. |
