| Author: | B. Nawrocka |
| Abstract:
The frit fly /Oscinella frit L./ has become the most serious pest of sweet corn in Poland in the last several years. Field population estimates on the number of injured plants during a 5 year study was high. The average number of damaged plants was 45 % and the yield decrease was 22.5 %. Injuries caused by frit fly larvae were satisfactorily controlled with insecticides applied as a seed dressing. The best results were observed with 35 % carbofuran, 30 % carbofuran with captan, 67 % furathiocarb and 25 % carbosulfan. | |
