Factors Influencing Pre‐emergence Mortality in Peas

Plant Pathology, 1968
SUMMARY Seedling emergence of 25 samples of wrinkle‐seeded peas ( Pisum sativum L.) was determined in unsterilized soil and sterilized sand at 15°C in the laboratory, and in a spring sowing in the field.

Weed control in sesame with pre-emergence herbicides

Indian Journal of Weed Science, 2018
Pendimethalin, imazethapyr, metribuzin, oxyfluorfen, imezemox were evaluated as pre-emergence herbicides in sesame during summer season of 2013 and 2014 at ICAR-Directorate of Weed Research, Jabalpur. All the herbicides reduced the weed population significantly as compared with weedy check but delayed the germination of sesame and caused sesame injury.

Fall Planting Pre-Emergence Lettuce Insecticides, 1990

Insecticide and Acaricide Tests, 1991
Abstract Coated lettuce seed were planted 25 Sep in double rows on beds with 40 inch centers at the Yuma Valley Agricultural Center. Seed rows were left open to allow insecticide applications on 26 Sep. Plots were 1 bed (2 rows) by 25 ft long. Treatments were relicated four times in a randomized complete block design.

Tolerances of wheat cultivars to pre-emergence herbicides

Australian Journal of Experimental Agriculture, 1985
Twelve 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, 1992
Abstract 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, 1960
THE 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
