Abstract Numerous annual and perennial weeds infest sugarcane. End-season weed infestations are managed before sugarcane is replanted by fallowing (cultivation sequential glyphosate applications) or rotating to glyphosate-tolerant soybean in Louisiana. With the occurrence of grasses glyphosate-resistant weeds, growers need utilize alternative late POST (LPOST) herbicide programs reduce newly planted (soybean-sugarcane rotation). Current rotational restrictions limit use acifluorfen,...
Field experiments were conducted in 2004, 2005, and 2006, at Pendleton, SC, to determine the effects of soybean canopy tillage on Palmer amaranth emergence from sites with a uniform population amaranth. In effect was evaluated only no-tillage plots. emerged May 10 through October 23, 13 September 2, April 28 August 25 respectively. Two three consistent periods occurred early mid-July. Shallow (10-cm depth) spring had minimal influence cumulative Increase light interception following...
Abstract Earlier reports have summarized crop yield losses throughout various North American regions if weeds were left uncontrolled. Offered here is a report from the current WSSA Weed Loss Committee on potential due to based data collected of United States and Canada. Dry bean loss estimates made by comparing dry in weedy control with plots that had >95% weed research studies conducted growing Canada over 10-year period (2007 2016). Results these field showed growers Idaho, Michigan,...
Abstract The widespread evolution of herbicide resistance in weed populations has become an increasing concern for no-tillage (NT) growers semiarid regions the U.S. Great Plains. Lack cost-effective and alternative new sites action further exacerbates problem herbicide-resistant (HR) weeds threatens long-term sustainability prevailing cropping systems region. A recent decline commodity prices costs to manage HR spurred research efforts build a strong rationale developing ecologically based...
The Midwestern U.S. landscape is one of the most highly altered and intensively managed ecosystems in country. predominant crops grown are maize (Zea mays L.) soybean [Glycine max (L.) Merr]. They typically as monocrops a simple yearly rotation or with multiple years (2 to 3) followed by single year soybean. This system productive because management systems have been well adapted regional growing conditions through substantial public private investment. Furthermore, markets supporting...
Hypercholesterolemia is an emerging problem affecting population now a days and responsible for CVD, HTN, Diabetes. Not following Dincharya, Ritucharya, smoking, consuming alcohol, lack of exercise, stress, intake fast food are one common cause hypercholesterolemia. can be compared in Ayurveda as Medodusti which due to excessive Sleshmavradhaka Ahara (heavy food) leads Agnimandhya (diminished digestive fire) turn that abnormal accumulation Meda (Cholesterol).

Okra (Abelmoschus esculentus) is an important vegetable crop that cultivated in tropical and subtropical regions of the world. It mostly grown for its delicate fruit, stem, flower bud. Like other crop, okra also attacked by many diseases. Among all diseases, leaf spot major disease which causes heavy loss to crop. During isolation identification it was identified as Cercospora varied their cultural morphological character. Pathogenecity test proved using Koch’s postulates. course study, 4...
Experiments were conducted on Palmer amaranth seeds collected in 2004 and 2006 from a natural population near Pendleton, SC, to determine the temperature light requirements for germination of retrieved soil surface or 10-cm depth field. A cyclic change seed response occurred during 12-mo after-ripening period. Freshly matured November required mean temperatures ≥ 25 C, red (R) increased germination. Following winter, experienced reduction dormancy germinated higher at 35 C compared with 10...
Seeds of a suspected glyphosate-resistant giant ragweed biotype from Lauderdale County, TN, were collected continuous cotton field in fall 2007 after plants nonresponsive to multiple glyphosate applications. The objectives this research (1) confirm resistance by quantifying the response putative resistant compared susceptible nonagricultural area, (2) quantify shikimate accumulation over time both biotypes, and (3) determine effectiveness POST-applied herbicides labeled for use controlling...
Glyphosate-resistant (GR) Kochia scoparia has evolved in dryland chemical fallow systems throughout North America and the mechanism of resistance involves 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS) gene duplication. Agricultural fields four states were surveyed for K. 2013 tested glyphosate-resistance level EPSPS copy number. Glyphosate was confirmed populations collected from sugarbeet Colorado, Wyoming, Nebraska, Montana. also accessions wheat-fallow All GR samples had increased...
A segment of the field precision agriculture is being developed to accurately and quickly map location herbicide-resistant herbicide-susceptible weeds using advanced optics computer algorithms. In our previous paper, we classified kochia [<italic>Bassia scoparia</italic> (L.) Schrad.] ground-based hyperspectral imaging a support vector machine learning algorithm, achieving classification accuracies up 80%. current work, imaged along with marestail (also called horseweed) [<italic>Conyza...
Abstract The herbicides that inhibit 4-hydroxyphenylpyruvate dioxygenase (HPPD) are primarily used for weed control in corn, barley, oat, rice, sorghum, sugarcane, and wheat production fields the United States. objectives of this review were to summarize 1) history HPPD-inhibitor their use States; 2) resistant weeds, mechanism resistance, management; 3) interaction with other herbicides; 4) future HPPD-inhibitor-resistant crops. As 2022, three broadleaf weeds (Palmer amaranth, waterhemp,...
Experiments were conducted to investigate the acclimation of Palmer amaranth shading. Plants grown in field beneath black shade cloths providing 47 and 87% full sunlight (no shading). All photosynthetic measurements taken 4 wk after initiating treatments. Photosynthetic rates under 47% increased with increasing active radiation (PAR) similar 0% shade-grown plants. Light-saturated predicted beyond highest measured PAR 1,200 µmol m −2 s −1 for plants 0 shade. acclimated shading by decreasing...
Summary Experiments were conducted to compare growth characteristics, biomass production and glucosinolate content of seven autumn‐planted glucosinolate‐producing cover crops that terminated the following spring. The control Digitaria sanguinalis Amaranthus palmeri crop incorporation into soil was characterised fruit yields bell pepper transplanted crop‐amended determined. Differences in concentration composition noted between roots shoots among crops. Total by ranged from 103 g m −2 for...
Field experiments were conducted in 2004 and 2005 at Clemson, SC, Clinton, NC, to quantify Palmer amaranth large crabgrass growth interference with plasticulture-grown bell pepper over multiple environments develop models which can be used on a regional basis effectively time removal of these weeds. Experiments both locations consisted an early late spring planting, the crop weeds planted alone combination. Daily maximum minimum air temperatures calculate growing degree days (GDD, base 10 C)...
Glyphosate-resistant giant ragweed in Arkansas was reported 2005. A study conducted to (1) confirm and characterize the glyphosate resistance ragweed, (2) determine if reduced absorption or translocation is mechanism of (3) evaluate efficacy nine POST-applied soybean herbicides control glyphosate-resistant -susceptible ragweed. Based on rate required kill 50% plants (LD 50 values), resistant biotypes from Greene Jefferson counties were 2.3- 7.2-fold less sensitive compared susceptible...
Bromus tectorum L. is one of the most troublesome grass weed species in cropland and non-cropland areas northwestern USA. In summer 2016, a B. tectroum accession (R) that survived imazamox at field-use rate (44 g ha-1 ) an imidazolinone-tolerant (IMI-tolerant or Clearfield™) winter wheat field was collected from Carter County, MT, The aim this study to determine resistance profile R other ALS inhibitors, investigate mechanism imazamox.The had high-level (110.1-fold) (IMI) low moderate-levels...
