Background: The herbicide RoundUp® became widely used in agriculture in the mid-1990s. Current populations of the crop weed Ipomoea purpurea exhibit both resistance and tolerance to RoundUp, which are two types of defence that have previously been shown to have a genetic basis in this weed species. Questions: Did the genetic basis of RoundUp defence antedate the introduction of RoundUp? If so, ...

Palmer amaranth, a dioecious summer annual species, is one of the most trouble‐ some weeds in the agronomic crop production systems in the United States. In the last two decades, continuous reliance on herbicide(s) with the same mode of action as the sole weed management strategy has resulted in the evolution of herbicideresistant (HR) weeds, including Palmer amaranth. By 2015, Palmer amaranth ...

ABSTRACT-Several herbicides are registered for selective weed control in sugar beet; however, no single chemical herbicide can control all weeds in beet fields. Frequently, two or more herbicides may have to be combined sequentially or as tank mixed to achieve adequate broad-spectrum weed control. In order to evaluate the effects of some combinations of broadleaf herbicides on sugar beet yield ...

Nowadays, artificial intelligence (AI) has a big impact in the field of painting. In contrast to hand-painting and challenging personal creativity, AI applications practices add noise, remove restore image conserve present process after converting data. The various generator models, Diffusion model is latest application consist two main word-image mapping diffusion algorithm. This article intro...

There is an urgent need for rapid, accurate, and economical screening tests that can deter‐ mine if weeds surviving a herbicide application are resistant. This chapter describes de‐ velopment and application of a simple root length bioassay technique for detection of wild mustard (Sinapis arvensis L.) resistance to ALS-inhibiting herbicides. This bioassay was performed in 2-oz WhirlPak® bags fi...

Seed dressing, i.e., the treatment of crop seeds with insecticides and/or fungicides, aiming to protect seeds from pests and diseases, is widely used in conventional agriculture. During the growing season, those crop fields often receive additional broadband herbicide applications. However, despite this broad utilization, very little is known on potential side effects or interactions between th...

A hierarchical framework is proposed to address the issues of modeling different type of words in keyword spotting (KWS). Keyword models are built at various levels according to the availability of training set resources for each individual word. The proposed approach improves the performance of KWS even when no training speech is available for the keywords. It also suggests an easier way to co...

James R. Mahan Plant Stress and Water Conservation Laboratory, USDA-ARS, 3810 Fourth Street, Lubbock, TX 79415-3397 Pyrithiobac control of Palmer amaranth on the Texas Southern High Plains was correlated previously with temperature at the time of application. In the present study, the thermal dependence of pyrithiobac efficacy was used to define a thermal application range (TAR) for postemergen...

In a previously reported model study, sugarcane was genetically engineered with the pat gene conferring resistance to the herbicide Buster®. The sugarcane cultivar used in that work was NCo310, which is no longer grown commercially but responds well to tissue culture and transformation. The field performance of the herbicide resistant sugarcane was assessed and stable transgene expression obser...
