Fabricating supramolecular pre-emergence herbicide CPAM-BPyHs for farming herbicide-resistant rice [PDF]

Nature Communications
Controlling weeds before their emergence is crucial for minimizing their impacts on crop yield and quality. Bipyridyl herbicides (BPyHs), a class of highly effective and broad-spectrum herbicides, cannot be used as pre-emergence herbicides because they ...

The implications of spatially variable pre-emergence herbicide efficacy for weed management. [PDF]

Pest Manag Sci, 2018
BACKGROUND The efficacy of pre-emergence herbicides within fields is spatially variable due to soil heterogeneity. We quantified the effect of soil organic matter on the efficacy of two pre-emergence herbicides; flufenacet and pendimethalin, against A.

Development of the novel pre-emergence herbicide pyroxasulfone. [PDF]

J Pestic Sci, 2016
Pyroxasulfone, which was discovered and developed by K-I Chemical Research Institute Co., Ltd.; Kumiai Chemical Industry Co., Ltd.; and Ihara Chemical Industry Co., Ltd., is a novel pre-emergence herbicide for wheat, corn, and soybean. Pyroxasulfone inhibits the biosynthesis of very-long-chain fatty acids in plants and has shown excellent herbicidal ...

State-Contingent Demand for Herbicide-Tolerance Seed Trait [PDF]

Journal of Agricultural and Resource Economics, 2003
Suppose a farmer had to apply a herbicide pre-emergence or not at all. The advent of a herbicide-tolerance trait innovation then provides the option to wait for more information before making a state-contingent post-emergence application.

Evaluating Sensor-Based Mechanical Weeding Combined with Pre- and Post-Emergence Herbicides for Integrated Weed Management in Cereals

Agronomy, 2022
Due to the increasing number of herbicide-resistant weed populations and the resulting yield losses, weed control must be given high priority to ensure food security.

Combined Pre- and Post-Emergence Herbicides for Effective Weed Control in Alfalfa (Medicago sativa L.) [PDF]

Plants
The scarcity of effective selective herbicides has made weed management a limiting factor for alfalfa yield and large-scale cultivation. This study aimed to preliminarily screen selective herbicides with acceptable safety to alfalfa and establish an ...

Weed Response to Different Tank-Mix Herbicide Combinations and its Impact on Winter Rice Performance in Zero Till Non-Puddled Condition

Fundamental and Applied Agriculture
Tank-mixture of two or more chemical groups of either pre- or post-emergence herbicide might play a vital role to manage weeds of a diversified community more effectively than their single or sequential application.

Selectivity of Herbicide Associations with Chemical Protector in the Treatment of Sweet Sorghum Hybrid Seeds [PDF]

Planta Daninha, 2017
Sweet sorghum culture is an alternative to sugar and ethanol production. With the aim of evaluating herbicide tank-mix selectivity associated or not to sweet sorghum seed treatment with naphthalic anhydride, two experiments with ESX5200 and EJX7C5110 ...

EFFICACY AND SELECTIVITY OF HERBICIDES APPLIED IN CASSAVA PRE-EMERGENCE [PDF]

Revista Caatinga, 2018
The interference imposed by weeds can cause damages to cassava development. Thus, adopting control measures is fundamental. The use of pre-emergence herbicides is one of the control alternatives, since cassava presents a good tolerance to herbicides ...

Junglerice (Echinochloa colona L.) seedling emergence model as a tool to optimize pre-emergent herbicide application [PDF]

Italian Journal of Agronomy, 2021
Junglerice (Echinochloa colona), one of the worst and most problematic weeds in the world, causes large economic losses as a result of yield loss and control cost increase.
