| Popis: | in greenhouse and growth - chamber studies, increasing the level of either light or temperature increased bentazon (3 - isopropyl - 1H- 2,1,3 -benzothiadiazin - 4(3H) - one 2,2 - dioxide) phytotoxicity to cucumber (Cucumis sativus L.). Light had a greater influence on phytotoxicity than did temperature. Light and temperature conditions after bentazon application had a greater influence on phyto - toxicity than did light and temperature conditions before application. Maximum phytotoxicity was obtained from treatment with low light level before application and high light level after application. mental conditions. Light has been shown to be necessary for necrosis of common cocklebur (Xantbium pensylvanicum Wallr.) leaves after treatment with bentazon and necrosis developed faster at higher illuminance levels (10). Common lambsquarters (Chenopodium album L.) was most susceptible to bentazon when exposed to low levels of irradiance before and high levels after bentazon application (2). Common cocklebur and redroot pigweed (Amaranthus retroflexus L.) were most susceptible to bentazon at high temperature and relative humidity levels (8, 11). Velvetleaf (Abutilon theo - pbrasti Medic.) was also more susceptible to bentazon at high relative humidity (4). Common lambsquarters, however, was most susceptible to bentazon when exposed to low temperature before and high temperature after application (2). |
