Abstract Tolpyralate is an herbicide that usually mixed with atrazine for broad-spectrum weed control in corn. Previous research has provided information on the effective dose (ED) of tolpyralate applied alone and a 1:33.3 mixture atrazine; however, commercially at 30 to 40 g ai ha −1 minimum 560 atrazine. Therefore, five field trials were conducted over 3 yr (2019 2021) determine ED complement...

Understanding the spectral characteristics of crops in response to stress caused by weeds is a basic step improving precision agricultural technologies that manage field. This research focused on competition between corn (Zea mays) and redroot pigweed (Amaranthus retroflexus), common weed strongly reduces yield. The aim this was characterize physiological changes occur during early growth becau...

abstract in order to study the effect of different organ extracts of fenugreek (trigonella gracum (on germination of some crops and weeds, an experiment was conducted in completely randomized design with 3 replications. factors included 4 species soybean (glysin max),sesame ( sesamus indicum) , pigweed (amaranthus retroflexus) and velvetleaf (abotilon teophrasti) and the extract of different fe...

Collaborative Knowledge Bases such as Freebase [1] and Wikidata [2] mention multiple professions and nationalities for a particular entity. The goal of the WSDM Cup 2017 [3] Triplet Scoring Challenge was to calculate relevance scores between an entity and its professions/nationalities. Such scores are a fundamental ingredient when ranking results in entity search. This paper proposes a novel ap...

biology of amaranth stem-boring weevil, hypolixus pica (fabricius) on red root pigweed, amaranthus retroflexus l. was investigated under natural conditions in a citrus orchard in dezful. each red root pigweed was covered by a wooden cage of 50×50×100cm dimentions screened by muslin. three to four adult females and males were introduced into each cage. after 3-4 days past the weevils were remove...

in this research corn were planted in 3 densities (8, 12, 16 plant/m2) in two planting patterns (single and double-row) with seven summer weed species, including redroot pigweed, green foxtail, annual bluegrass, common lambsquarter, jimsonweed, black nightshade and johnsongrass were planted. temperature, quality and quantity of light reaching to soil surface were measured and the number of emer...

Green pigweed [Amaranthus powellii S. Wats.] is a competitive, annual, broadleaf weed that can significantly reduce soybean yield due to rapid early growth and biomass production. As consequence of green pigweed’s high competitiveness with crops, the species generally managed use herbicides; this may, however, lead selection resistance. A biotype resistance MCPA, mecoprop, dichlorprop-p, aminoc...
