Abstract
Effects of temperature on response of transplanted tomatoes ( Lycopersicon esculentum Mill. ‘Campbell 17′) to trifluralin (α,α,α-trifluoro-2,6-dinitro- N,N -dipropyl- p -toluidine), nitralin [4-(methylsulfonyl)-2,6-dinitro- N,N -dipropylaniline], profluralin [ N -(cyclopropylmethyl)-α,α,α-trifluoro-2,6-dinitro- N -propyl- p -toluidine], and isopropalin (2,6-dinitro- N,N -dipropylcumidine) were investigated in field studies. Trifluralin and nitralin caused greater reductions in growth and yields of tomatoes transplanted early in April than to tomatoes transplanted around May 1. Responses to profluralin were similar but total yields of early transplanted tomatoes were not reduced although initial yields were below those of tomatoes treated with isopropalin. In controlled environment chamber studies, percent phosphorus of plant tops was reduced by trifluralin at low temperatures but was not influenced by trifluralin at high temperatures. Tomoto responses to phosphorus as reflected by plant fresh weight, dry weight and phosphorus content (mg/plant) were reduced by trifluralin at low and high temperatures.
