The two most commonly used fumigant formulations, one generating hydrogen cyanide (HCN) and the other phosphine (PH3), were compared in paired field trials using the spoon-gassing technique. The two formulations were equally effective in reducing rabbit numbers seen in spotlight counts. The PH3 generating formulation was more convenient and slightly cheaper to use. Safety and humaneness aspects...

New alternative insecticides are necessary for the chemical control of head lice. In this study the fumigant knockdown time 50% (KT50) and repellency index (RI) of three aliphatic lactones was compared with two essential oils and DDVP, against permethrin-resistance Pediculus humanus capitis from Argentina. In the fumigant assay, none of the lactones were effective compared to the highest activi...

Volatilization and soil transformation are major pathways by which pesticides dissipate from treated agricultural soil. Volatilization is a primary source of unwanted agricultural chemicals in the atmosphere and can significantly affect fumigan...

Watermelon (Citrullus lanatus var. lanatus) yield losses due to Fusarium wilt can be considerable and have been increasing in the United States, mainly emergence of new races oxysporum f. sp. niveum (FON). One potential management strategies reduce is use fumigants soil-applied fungicides. Field experiments were conducted 2018 2020 evaluate fumigant Pic-clor 60 (choloropicrin pre-mixed with 1,3...
