Competitive effects and control of weeds in winter wheat on the Anatolian Plateau, Turkey

Creator:: Tezel, Cengiz
Abstract:: Wheat is the major crop produced on the Anatolian Plateau of Turkey. Annual weeds cause large yields reductions in the wheat crop. Several formulations of 2, 4-D and mixtures of 2, 4-D and 2,4, 5-T are the only materials currently available for use in Turkey on wheat. The objective of...

The persistence of five herbicides in Hawaiian soil

Creator:: Kitagawa, Yukio
Abstract:: The persistence of DCPA, trifluralin, diphenamid, diuron, and prometryne was studied in three soils which were located at the Kula, Poamoho, and Waimanalo Experiment Stations. The order of decreasing persistency was diuron, prometryne, trifluralin, DCPA, and diphenamid. Diuron and prometryne activities were recorded for at least six months and diuron...

Differential sensitivity of two common groundsel biotypes (Senecio vulgaris L.) to several s-triazine herbicides

Creator:: Radosevich, Steven R.
Abstract:: Studies were initiated to determine the response of two common groundsel biotypes (Senecio vulgaris L. ) to several s-triazine herbicides. Herbicides tested were: 2-chloro-4,6-bis(ethylamino)-striazine (simazine), 2-chloro-4-(ethylamino)-6-(isopropylamino)- s-triazine (atrazine) 2-(sec-butylamino)-4-(ethylamino)-6-methoxys- triazine (GS-14254), 2, 4-bis(isopropylamino)-6-methoxy-striazine (prometone), 2-(tert-butylamino)-4-(ethylamino)-6-methylthio- s-triazine (terbutryn), and 2, 4-bis(isopropylamino)-6- methylthio-s-triazine (prometryne). One biotype was much more susceptible than the...

The influence of various surfactant-herbicide ratios in three volumes of water on the toxicity of dalapon, paraquat, and terbacil to winter oats (Avena sativa L.)

Creator:: Migchelbrink, Kenneth John
Abstract:: Several studies were conducted to determine if a more consistent predictor of phytotoxicity to winter oats could be obtained with a surfactant-herbicide ratio or a per-unit-volume concentration of surfactant, independent of volume. The herbicides tested were 2,2-dichloropropionic acid (dalapon), 1,1'-dimethyl-4, 4'-bipyridinium (paraquat), and 3-tert-butyl-5-chloro-6-methyluracil (terbacil) with the nonionic surfactant X-77...

The response of tomatoes to atrazine as affected by magnesium and photoperiod

Creator:: Brenchley, Ronald Glenn
Abstract:: Studies were conducted to determine the nature of the interaction between atrazine (2-chloro-4-ethylamino-6-isopropylaminos- triazine) and magnesium on tomatoes. This interaction was studied under two light regimes: continuous light and a 12-hour photoperiod. Tomato plants were grown in sand cultures at three levels of magnesium fertilization. Four weeks after planting, atrazine...

Indole-3-acetic acid in (2-chloroethyl)-trimethylammonium chloride-treated club wheat (Triticum aestivum compactum)

Creator:: Gould, Walter Leonard
Abstract:: Studies were conducted to verify the existence of IAA in wheat seedlings and to determine the effect of (2-chloroethyl)-trimethyl-ammonium chloride (CCC) on the IAA content of club wheat, Triticum aestivum compactum, variety Omar. The shoots of CCC-treated and untreated wheat plants were extracted with ethanol, the plant extract purified, separated...

Foliage applications of terbacil to peppermint (Mentha piperita) and several weed species

Creator:: Radosevich, Steven R.
Abstract:: Several studies were conducted to determine the feasibility of using terbacil (3-tert-butyl-5-chloro-6-methyluracil) postemergence to weeds and peppermint (Mentha piperita L.). Three nonionic surfactants, four nonphytotoxic oils, and a liquid fertilizer were each combined with 0.5 lb ai/A terbacil in 35 gallons of water per acre. Weed species tested include: redroot...
