Weed Control for Pot-In-Pot Production using Preemergence Herbicides

Weed Control and the Use of Herbicides in Sesame Production

Nitrogen and Substrate Assessment For Pot-in-Pot Production in the Intermountain West1

We investigated optimum nitrogen rates and different growth substrates for short-term fi nish production of container and bare root shade tree liners in a pot-in-pot production system in the Intermountain West. In one study, nitrogen ranging from 0–27 g N·tree–1 (0–36 lbs N·1000 ft–2) as urea was applied to quaking aspen (Populus tremuloides), ‘Autumn Blaze’ maple (Acer × freemannii ‘Autumn Bla...

Ragweed Parthenium (Parthenium hysterophorus) Control with Preemergence and Postemergence Herbicides

Field and greenhouse experiments were conducted during 2005 and 2006 at Stoneville, MS, to determine control of ragweed parthenium with several preemergence (PRE) and postemergence (POST) herbicides registered for use in corn, cotton, peanut, rice, and soybean. Norflurazon, pendimethalin, clomazone, diuron, fluometuron, pyrithiobac, dimethenamid, flumetsulam, imazaquin, s-metolachlor, metribuzi...

Microbial Weed Control and Microbial Herbicides

Microbial weed control represents an innovative means to manage troublesome weeds and utilize the naturally occurring biological herbicides produced by soil microorganisms. These compounds kill or hinder the growth of weeds so that beneficial plant species can gain a competitive advantage. The vast diversity of microorganisms in our environment is largely untapped, and the potential discovery a...

Pot economy and one-pot synthesis

The one-pot synthesis of a target molecule in the same reaction vessel is widely considered to be an efficient approach in synthetic organic chemistry. In this review, the characteristics and limitations of various one-pot syntheses of biologically active molecules are explained, primarily involving organocatalytic methods as key tactics. Besides catalysis, the pot-economy concepts presented he...
