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.

Atrazine nanoencapsulation improves pre-emergence herbicidal activity against Bidens pilosa without enhancing long-term residual effect on Glycine max.

Pest Management Science, 2019
BACKGROUND Poly(ϵ-caprolactone) nanocapsules (NC + ATZ) are an efficient carrier system for atrazine and were developed as an alternative to reduce the harmful environmental effects of this herbicide.

Evaluation of pre‐emergence herbicides for establishing coffee

International Journal of 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 ...

ANALYSIS OF PRE-EMERGENCY CONDITIONS OF LIFTING CRANES

Spravochnik. Inzhenernyi zhurnal
It is noted that currently a large proportion of lifting cranes with expired standard service lives are in operation in the country. The results of the analysis of the pre-emergency condition of lifting cranes, the causes of dangerous defects, which are foci of damage development, detected during expert examinations are presented.

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.
