Three perennial ryegrass (Lolium perenne) populations (R1, R2, and R3) with suspected resistance (R) to acetolactate synthase (ALS) or acetyl-CoA carboxylase (ACCase) herbicides were collected from wheat (Triticum aestivum) fields in northwestern Greece study the underlying mechanisms of their impact on growth rate competitive ability against wheat. Preemergence postemergence plant dose–respons...

College Agriculture Research Station, Bhatapara (C.G.). soil the experiment side clay- loam texture. crop grown in treatments were replicated three times split plot design. experimental ...

Management of hygrophila, a submersed non-native aquatic weed, is particularly challenging because few registered aquatic herbicides effectively control the species, which most commonly occurs in slow to moderately flowing canals, streams and rivers. Seven experimental or newly registered aquatic herbicides were evaluated in 10-wk static exposure studies to determine their activity on hygrophil...

BACKGROUND: Numerous studies have shown that combining the indigenous fungal pathogen, Mycoleptodiscus terrestris (Gerd.) Ostazeski, hereafter referred to as Mt, with low doses of herbicides has excellent potential as an integrated strategy for long-term management of hydrilla and Eurasian watermilfoil (Myriophyllum spicatum L.) (Netherland and Shearer 1996; Nelson et al. 1998; Shearer and Nels...

Kochia [Bassia scoparia (L.) A.J. Scott] is an invasive C 4 tumbleweed in the Great Plains of North America, where it impedes crop harvest and causes significant yield losses. Rapid evolution spread glyphosate- acetolactate synthase (ALS) inhibitor-resistant kochia western Canada limit herbicide options available for control these biotypes field pea (Pisum sativum L.); one predominant pulse cro...

A study was carried out to determine the ALS (acetolactate synthase)-inhibitor herbicide resistance in Mexican grass Ixophorus unisetus, a troublesome weed corn crops Mexico. First, confirmed field screening assays. Eight populations that survived nicosulfuron treatment at rate of 40 g ai ha−1 were labeled as putative-resistant. Dose–response trials demonstrated high eight (GR50 from 140.33 245...

Abstract Late watergrass [ Echinochloa phyllopogon (Stapf) Koss.] has evolved multiple-resistance (MR) to herbicides in many areas worldwide and scientists wonder if this resistance imposed fitness cost or advantage on the resistant biotypes. As of weed also been recorded Greece, one susceptible (S), with ALS (penoxsulam, bispyribac, imazamox nicosulfuron + rimsulfuron) ACCase-cyhalofop (MRAC) ...

Eleusine indica is a highly competitive and difficult-to-control plant in annual perennial crops. In Colombia, broad-spectrum herbicides, such as paraquat glyphosate, have begun to present poor levels of control for this weed. The multiple resistance glyphosate paraquat, the increase herbicide performance with adjuvants (Retenol® Trend® 90), alternative herbicides were evaluated resistant (R) p...
