Pre- and post-emergent effects on caste

2022
Long fascinated and puzzled researchers, eusociality and the evolutionary mechanisms selecting for and maintaining it are most easily observed within insect societies. In eusocial paper wasps, reproduction is limited to a small subset of females while the remainder forage and feed and care for the offspring.

Efficacy of Post Emergence Herbicides in Groundnut

LEGUME RESEARCH - AN INTERNATIONAL JOURNAL, 2020
Background: Groundnut encounters severe infestation of weed especially during the early stages of growth due to less crop canopy which allows higher weeds growth and thus crop becomes more susceptible to weed competition. During rainy season, effective and economical weed control is not possible through manual and mechanical weeding due to unfavorable ...

Developments in post-emergence herbicide applicators

Outlook on Agriculture, 1981

Post-Emergence Control of Broomrape with Natural Plant Oils

Journal of Sustainable Agriculture, 1998
ABSTRACT The effect of natural oils on broomrape (Orobanche cernua Loefl.) was assessed in a naturally infested tobacco (Nicotiana tabacum L.) field at the Agricultural Research Station, Nipani, India, during 1994–95. Natural oils which are available at low cost and biodegradable differed in their ability to kill the young broom-rape spikes.

Possibilities of mechanical post-emergence weed control in sugar beet

Soil and Tillage Research, 1991
Abstract During a period of four years, 1986–1989, a number of field experiments on post-emergence weed control in sugar beet was carried out. The experiments are components of five weed control systems: chemical; integrated; integrated including ridging; mechanical; mechanical with plants in squares.
