Broad spectrum weed control is essential for successful lesquerella [Lesquerella fendleri (Gray) Wats., Brassicaceae] production. Weeds must be controlled during establishment and throughout the growing season. Lesquerella seedlings grow slowly following germination and emergence, and cannot compete well with most broadleaf and grass weeds. Weed competition is particularly critical prior to clo...

Ischaemum rugosum Salisb. (Saramolla grass) is a noxious weed of rice that is difficult to control by chemical or mechanical means once established. A study was conducted to determine the effect of light, temperature, salt, drought, flooding, rice residue mulch, burial depth, and pre-emergence herbicides on seed germination and emergence of I. rugosum. Germination was stimulated by light and in...

Abstract Preemergence (PRE) herbicides are often banded over the entire top of raised beds for broadleaf and grass control in plasticulture vegetable production systems. However, weeds may emerge from planting holes tears plastic mulch. Banded application results applied where no occur, therefore, they not needed. Our objective is to identify that do harm transplanted crops when directed at tra...

A field experiment was carried out in the year 2014 and 2015 at experimental of Banaras Hindu University, Varanasi, Uttar Pradesh to evaluate effect agronomic weed management practices on crop growth rate (CGR) relative (RGR) direct seeded rice. Twenty-four treatment combinations consisting two mulching viz. no mulch live (brown manuring with Sesbania) nitrogen levels (120 kg ha-1, 150 ha-1&nbs...
