Interaction between glyphosate and certain s-triazine herbicides

Creator:: Somabhi, Montien
Abstract:: Investigations were made in the field, greenhouse, growth chamber, and laboratory to: (a) observe the general activity of N- (phosphonomethyl)glycine (glyphosate); (b) determine the extent of its interaction with certain s-triazine herbicides; and (c) find an explanation for such an interaction. Greenhouse and growth chamber studies substantiated other observations that...

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...

Dinitroaniline-herbicide resistance in goosegrass (Eleusine indica) : ecophysiological aspects

Creator:: Valverde, Bernal E.
Abstract:: Growth of individual goosegrass (Eleusine indica (L) Gaertn.) plants of three dinitroaniline-herbicide resistant (R) and three susceptible (S) biotypes from North Carolina, South Carolina, and Mississippi was analyzed in greenhouse experiments. Leaf area and biomass measurements, including root, shoot, above-ground, and total dry weights were similar among the biotypes studied....

Degradation of the herbicide EPTC in three Willamette Valley soils

Creator:: Coleman, Quentin Charles
Abstract:: EPIC (S-ethyl dipropylthiocarbamate) is a selective herbicide which controls some annual grasses, annual broadleaves, and perennial grasses when incorporated into the soil before planting. In the last few years, reports have been received of certain fields in the Willamette Valley of Oregon in which EPIC was no longer effective. Preliminary...

Tobacco rattle virus : weed hosts, diagnosis, characterization, purification, and interaction with potato virus X

Creator:: Locatelli, Eduardo Atilio
Abstract:: A series of studies was conducted to determine the presence of tobacco rattle virus (TRV), potato virus X (PVX), and other viruses in wild plants and to evaluate the efficacy of the detection methods; to characterize and purify an isolate of TRV; and to study the interaction between TRV and...

Apoplastic distribution of atrazine and glyphosate in intact sunflower leaves

Creator:: Jachetta, John Joseph
Abstract:: Apoplastic distribution patterns of atrazine [2-chloro-4-(ethylamino)- 6-(isopropylamino)-s-triazine], glyphosate [N-(phosphonomethyl)- glycine], the naturally occurring apoplastic leaf solutes, and the apoplastic dye PTS (trisodium 3-hydroxy-5,8,10-pyrenetrisulfonate) were compared. Aliquots of sap were expressed from intact sunflower leaves in a pressure chamber over intervals of 0.2 to 0.4 bars. Three distinct fractions were detected...

The effect of 2,4-D on the respiration rate and ethylene production of Bartlett pears and Red Delicious apples

Creator:: Fechtig, Allen David
Abstract:: After nearly 20 years of commercial use in orchards without apparent tree injury in Oregon and Washington, 2,4-D [(2,4-dichlorophenoxy) acetic acid] was reported in 1970 to cause injury to apple and pear trees in Washington. In the early 1970's, there was widespread concern among growers, researchers, and processors in the...

Factors influencing metribuzin use in strip-planted wheat

Creator:: Zeghida, Ali
Abstract:: Equipment for strip-till planting is under development in wheat-fallow rotations in the Columbia Basin of Oregon. This involves the absence of tillage during the fallow season. At planting time, the strip-till planter creates a narrow band into which the wheat seed is placed. The area between the rows is undisturbed...
