The tetrazole analogue of the auxin indole-3-acetic acid binds preferentially to TIR1 and not AFB5 [PDF]
, 2018 Auxin is considered one of the cardinal hormones in plant growth and development. It regulates a wide range of processes throughout the plant. Synthetic auxins exploit the auxin-signalling pathway and are valuable as herbicidal agrochemicals. Currently, despite a diversity of chemical scaffolds all synthetic auxins have a carboxylic acid as the active ...

Measuring specialty crop grower willingness to pay for genetic modification and genetic editing
Agribusiness, EarlyView.Abstract In contrast to the widespread adoption of agricultural commodities modified using biotechnology, the adoption rate of bioengineered specialty crops by growers remains low. The use of bioengineered crops has been controversial since their introduction in the 1990s due to concerns about their potentially harmful effects to human health, the ...

Effect of risk and incentives on contracts: The case of farm operators in Iowa
Agribusiness, EarlyView.Abstract Longitudinal data on Iowa landowner–operator contracts are used to examine how the mean, variance, and skewness of expected farmland returns affected contract terms from 2008 to 2019. To control for unobserved operator risk preferences and ability as a fixed effect, the sample includes operators with multiple contracts.

Detecting herbicide-resistant Apera spica-venti with a chlorophyll fluorescence agar test
Plant, Soil and Environment, 2018 Reliable tests on herbicide resistance are important for resistance management. Despite well-established greenhouse bioassays, faster and in-season screening methods would aid in more efficient resistance detection.

Supervised learning for crop/weed classification based on color and texture features [PDF]
arXiv, 2021 Computer vision techniques have attracted a great interest in precision agriculture, recently. The common goal of all computer vision-based precision agriculture tasks is to detect the objects of interest (e.g., crop, weed) and discriminating them from the background. The Weeds are unwanted plants growing among crops competing for nutrients, water, and
