Field experiments were conducted during 2017 and 2018 to evaluate the efficacy of herbicides NICOSULFURON and EPTC alone or in combination with seed priming on weed control and corn yield. NICOSULFURON (80 g a.i. ha‒1) was applied at four- to six-leaf stage of corn as post-emergence and EPTC (4920 g a.i. ha‒1) applied as pre-plant incorporation (PPI). Among the herbicide treatments, the lowest ...

Chloropicrin fumigation, Eptam 7-E (EPTC) herbicide, and Paenibacillus macerans seed treatments were evaluated as alternatives to fumigation with methyl bromide/chloropicrin for loblolly pine (Pinus taeda L.) seedling production at three nurseries in the southern United States. A treatment of metam sodium/chloropicrin was also evaluated at one nursery. Seedling density was unaffected by fumigat...

in order to study the effect of planting pattern and herbicide application on corn (zea mays l.) grain yield and weeds control, an experiment was carried out in 2007 at varamin research station of plant protection research institute. the experimental design was a randomized complete block in a split plot arrangement with 4 replications. experimental factors consisted of planting patterns at 4 l...

in order to study of the effect of nitrogen source, operation method and weed control methods on weed biomass, yield and yield components of corn (zea mays l.) an experiment was carried out as split plot factorial based on randomized complete block design (rcbd) with four replications in shahrood university of technology. the treatments included weed control methods at four levels (hand weeding...

Treatments wilh the herbicides chlorpropham (isopropyl m-chlorocarbinilate), DCPA (dimethyl tetrachloroterephthalate), and El'TC (S-ethyl dipropylthiocarbamate), alone or in combination with Meloidogyne hapla Chilwood, significantly reduced the growth of both nemalode-resistant 'Nev Syn XX' atttt susceptible 'Ranger" alfalfa (Medicago saliva L.) seedlings. M. hapla infection of both alfalfas wa...

in order to evaluate the effect of rimsulfuron, eptc (eradican), oxadiargyl, metribuzin and metribuzin herbicides for controling of lambsquarter (chenopodium album) and prostrate pigweed (amaranthus retroflexus), an experiment was conducted at the mohaghegh ardabili university green house in 2008. a dose-response assay was conducted based on completely randomized design with four replications. ...

Trends in pesticide concentrations for 15 streams in California, Oregon, Washington, and Idaho were determined for the organophosphate insecticides chlorpyrifos and diazinon and the herbicides atrazine, s-ethyl diproplythiocarbamate (EPTC), metolachlor, simazine, and trifluralin. A parametric regression model was used to account for flow, seasonality, and antecedent hydrologic conditions and th...
