Abstract
Field trials were conducted under zero-tillage conditions to study broadspectrum annual weed control with applications of paraquat and glyphosate.Broadleaf herbicides were mixed wth the paraquat and glyohosate treatments to find their.impacton the effectiveness and cost for chemical seedbed preparation.Excellent broadleaf annual weed control resuited when 0'28 kglha of bromoxyni 1 was added to 0'42 kg/ha of paraquat.Excellent resuits were also obtained with 0.035 kg/ha of picloram' 0'14 kg/ha of dicamba or 0.28 kg/ha of bromoxyni in combination vlith 0.28 kg/ha of glypho- sate.when broadleaf herbicides were not added,.excellent broadspec- trum annual weed control required 0.56 kg/ha of paraquat or 0'42 kg/ha of glyphosate.The addjtion of broadleaf herbicides to 0.28 kg/ha of glyphosate was not necessary when wild oats or 'lamb's quarters were the only weed problem at seeding time.However, good control of wild mustard or wild buckwheat required the addition of 0.14 kg/ha of dicamba to 0.28 kg/ha of glyphosate' Paraquat at 0'28 kglha also gave very good control of wild mustard.ttIThe addition of surfactant (0.5 per cent of spray solution) was found to increase the phytotoxicty of glyphosate mixtures to wild oats.Experiments investigating the date of seeding under zero-tillage crop production showed that in general the yield of spring wheat (cv.Napayo) decreased as seeding date was deiayed from May 3.However, yieds obtained on the third seeding date (May 17) were greater than prior and subsequent seeding dates.These higher yields were attributed to improved moisture conditions at this seeding date.
