Recent developments in fluorine‐containing pesticides

Pest Management Science, Volume 80, Issue 7, Page 3065-3087, July 2024.
In the timeframe 2016–2022, approximately 77% of the 39 launched products (herbicides, fungicides, insecticides, acaricides, and nematicides) were halogen‐substituted and from these, approximately 64% were fluorine‐containing pesticides. Abstract To ensure ongoing sustainability, the modern agrochemical industry is faced with enormous challenges. These

Exploring the effects of red light night break on the defence mechanisms of tomato against fungal pathogen Botrytis cinerea

Physiologia Plantarum, Volume 176, Issue 4, July/August 2024.
Abstract Plant infections caused by fungi lead to significant crop losses worldwide every year. This study aims to better understand the plant defence mechanisms regulated by red light, in particular, the effects of red light at night when most phytopathogens are highly infectious.

Finger millet (Eleusine coracana) improvement: Challenges and prospects—A review

Plant Breeding, Volume 143, Issue 3, Page 350-374, June 2024.
Abstract Finger millet is a climate‐resilient and highly nutritious small grain crop widely grown in the semi‐arid tropics. It has multiple uses, including for food, feed and beverage preparations. However, finger millet is an under‐utilized and under‐researched crop with a mean yield of <1.0 t/ha despite a potential productivity of up to 8 t/ha.

A carbon dot toolbox for managing biotic and abiotic stresses in crop production systems

EcoMat, Volume 6, Issue 5, May 2024.
Carbon dots (C‐dots) are carbon‐based nanoparticles, smaller than 50 nm, exhibiting unique opto‐electro‐properties. Owing to versatile carbon chemistry, the surface functionalities of C‐dots can be readily tuned to regulate plant physiological processes for overcoming diverse biotic and abiotic stresses faced by the crops.
