Response of adzuki bean to pre-emergence herbicides
Canadian Journal of Plant Science, 2006Limited herbicide options are available to adzuki bean growers in southwestern Ontario. Six field trials were conducted in Ontario during 2003 and 2004 to evaluate the tolerance of adzuki bean to dimethenamid (1250 and 2500 g a.i. ha-1), S-metolachlor (1600 and 3200 g a.i. ha-1), clomazone (1000 and 2000 g a.i. ha-1), and imazethapyr (75 and 150 g a.i.

Tolerances of wheat cultivars to pre-emergence herbicides
Australian Journal of Experimental Agriculture, 1985Twelve spring wheat cultivars were tested in southern New South Wales for their tolerances to the recommended rates and three times the recommended rates of trifluralin, pendimethalin, tri-allate and chlorsulfuron. Recommended rates of these herbicides did not affect the emergence or grain yield of any cultivar.

Evaluation of pre‐emergence herbicides for establishing coffee
Tropical Pest Management, 1992Abstract Two field experiments were conducted to determine the safety of repeated applications of several pre‐emergence herbicides in coffee from the recently transplanted stage to 1 year old. Oryzalin and oxyfluorfen had at least a four‐fold selectivity margin to coffee at two locations; these herbicides had a greater safety margin than simazine ...

Pre-Emergence Herbicides on Alfalfa and Birdsfoot Trefoil
Weeds, 1960THE first step in a satisfactory forage-legume program on the farm T is the establishment of the legume. Success or failure here can mean the difference between a continued efficient rotation system and a financial loss. Many farmers have been reluctant to plow up old seedings at the proper time because of the cost of new seedings and the possibilities

Tolerance of Sorghum Genotypes to Pre-emergence Application of Herbicides
Madras Agricultural Journal, 1976A pot culture investigation was carried out to find out the tolerance of four sorghum genotypes viz., CSH 1, CSH 3, Swarna and GM 2-3-1 to pre emergence application of atrazine and 2, 4-D at 0.5 to 2.5 and 0.5 to 2.0 kg a. i. per ha, respectively. Application of higher dose of herbicide reduced germination of all the genotypes.

Application of pre-emergence herbicides in poplar nursery production
Journal of Forestry Research, 2015In addition to pests and diseases, weeds are a major problem in poplar nursery production. The possibilities of herbicide application in juvenile poplar growth were researched, taking into account that weeds are one of the main limiting factors. The following pre-emergence herbicides were tested: acetochlor, S-metolachlor, metribuzin, oxifluorfen, and ...

Replacement of atrazine with enviroment friendly pre-emergence herbicides
2008As an EU candidate country, Croatia is facing the implementation of new regulations on plant protection products. Atrazine banning requires new solutions for weed control. This paper compares the efficacy of registered herbicides in maize which can replace atrazine in pre-emergence.

EFFECT OF PRE-EMERGENCE HERBICIDES ON YIELD OF RAINFED SUNFLOWER
Madras Agricultural Journal, 1991A field study on the effect of pre-einergence herbicides in rainfed sunflower showed that pre-emergence application of Thiobencarb at 1.5 kg.ha¹ was more effective in control of the weeds and produced significantly higher seed yield over other herbicides viz., Oxadizon, Fluchloralin at 0.75 and 1.5 kg.ha 'N respectively and Thiobencarb at 0.75 kg.ha''.
