Changes In Weed Response To 2,4-D Application With 5 Repeated Applications In Spring Wheat, Hüseyi̇n Zengi̇n Jan 2001

Changes In Weed Response To 2,4-D Application With 5 Repeated Applications In Spring Wheat, Hüseyi̇n Zengi̇n

Turkish Journal of Agriculture and Forestry

2,4-D amine and 2,4-D isooctylester were sprayed repeatedly in the spring of 5 consecutive years on spring wheat (Triticum aestivum L.cv.Kırik)in Erzurum during the years 1990-1994. The herbicide efficacy against all broad-leaved weeds and against the most common weed species was determined by comparing the number of weeds in untreated and treated plots. The most abundant weed species were Polygonum aviculare, Amaranthus retroflexus and Chenopodium albumin spring wheat. The effect of 2,4-D amine decreased after 3 or 4 years in A.retroflexus, C.album,Convolvulus arvensis, Acroptilon repens, Lactuca serriola, P.aviculare, Cirsium arvense and other broad-leaved weeds. Effects against Sinapis arvensis and Sisymbrium …

Foliar Penetration Of Picloram And 2,4-D In Aspen And Balsam Poplar, M.P. Sharma, W.H. Vanden Born

Aspen Bibliography

Added surfactant (Atlox 210) at 1% (v/v) and high relative humidity enhanced the penetration of both 4-amino-3,5,6-trichloropicolinic acid (picloram) and (2,4-dichlorophenoxy)acetic acid (2,4-D0 into detached leaves of aspen poplar (Populus tremuloides Michx.).
