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...

The influence of herbicide placement in soil on toxicity to emerging seedlings

Creator:: Nishimoto, R. K. (Roy Katsuto), 1944-
Abstract:: Previous research has indicated several soil-applied herbicides are more effective by exposure to emerging shoots than from root uptake. Studies were conducted in the greenhouse and growth chamber to investigate effects of herbicide placement in soil on toxicity to emerging seedlings. In these studies, an inch of treated soil was...

Germination and growth characteristics of five accessions of jointed goatgrass (Aegilops cylindrica)

Creator:: Gleichsner, Jean A.
Abstract:: Laboratory and field studies were conducted at Pendleton, Oregon, during 1983 and 1984 to evaluate germination and growth characteristics of five jointed goatgrass (Aegilops cylindrica Host) accessions collected from sites in Echo, Ione, Pendleton, Condon, and Elgin, Oregon. Spikelets were germinated for 27 days at room (23 +̲ 2 C)...

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....

Intra- and interspecific interference between sweet corn (Zea mays L.) and a living mulch of white clover (Trifolium repens L.)

Creator:: Fischer, Albert J.
Abstract:: Living mulches are vegetative covers that can grow in association with row crops and may prevent soil erosion and suppress weeds. Crop reduction from association with the living mulch is a frequent problem with this cultural practice. The interference between a white clover (Trifolium repens L. "New Zealand") living mulch...

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...

Interaction of ethofumesate with dry soil

Creator:: McAuliffe, David
Abstract:: Previous studies have shown loss of ethofumesate activity when the herbicide was applied to dry soil (2% w/w moisture content) in both field and greenhouse studies, even when rainfall or irrigation was received within a few days. Laboratory studies were conducted to determine the mechanism for this activity loss. Dry...
