A New Approach: Ethyl Formate Fumigation to Control Bemisia tabaci (Hemiptera: Aleyrodidae) in a Yellow Melon Vinyl House

Due to concerns over the resistance development existing pesticides, chemical poisoning among farmers, and residue on crops, sprung up a growing need develop new pest control strategies for utilization in protected houses Korea. A series of experiments tested technology using fumigant, ethyl formate, crops houses. It was revealed that glasshouse inadequate fumigation system fumigant since formate gas sharply decreased due leaking through gaps between glass frames. On other hand, concentration stable during process. Experiments were also conducted evaluate its phytotoxicity cucurbits (yellow melon). The fumigated at 20 °C three schedules (2, 4, 12 h). results developmental stages yellow melon showed no sign all conditions. However, damaged shoots red pepper higher humidity longer duration. Interestingly, Bemisia tabaci (100%) completely killed these Based above high efficacy zero phytotoxic effects melon, verification effectiveness thrice farmer’s vinyl once cucumber house. Results demonstrated 2 h g m−3 could 100% kill adults with effect crops. Therefore, we conclude 2-h would be alternative spraying methods.
