Comparative Efficacies of Next-Generation Insecticides Against Yellow Stem Borer and Their Effects on Natural Enemies in Rice Ecosystem

Rice Science, 2019
The efficacies of some next-generation insecticides against the rice yellow stem borer (YSB), Scirpophaga incertulas (Walk.), and their compatibilities with natural enemies were investigated during 2014 and 2015.

Monosubstituted N‐Arylhydroxylamine Chemistry: Integrating Contemporary Synthetic Approaches for the Efficient Construction of Diverse Heterocyclic Scaffolds

Chemistry – A European Journal, EarlyView.
Monosubstituted N‐arylhydroxylamines represent a unique subclass of hydroxylamines that act as pivotal intermediates in redox transformations and as versatile platforms for further synthetic transformations. They serve as key building blocks in the synthesis of architecturally complex heterocycles and other valuable organic compounds.

Effect of Insecticides on Natural-Enemies

, 2022
Pesticides management options for control of invertebrate pests in many parts of the world. Despite an increase in the use of pesticides, crop losses due to pests have remained largely unchanged for 30–40 years. Beyond the target pests, broad-spectrum pesticides may affect non-target invertebrate species, including causing reductions in natural enemy ...

Nanofiber PVA‐Based Membranes Incorporating Functionalized Spanish Broom Derivatives for Sustainable Water Purification

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study investigates Spanish broom (Spartium junceum) as a renewable source for electrospun composite membranes in sustainable water purification. MCC and biochar were functionalized with eco‐friendly precursors and nanomaterials (i.e., HNT, β‐CDs) to develop hybrid PVA nanofiber composites.

Ecological engineering in cauliflower for aphid management

The Indian Journal of Agricultural Sciences, 2020
Because of high-value, the crops like Brassica have very low pest-damage thresholds, natural enemies alone are unlikely to replace use of high cost insecticides.

Toxicity of Natural Insecticides on Leptocorixa acuta

Tropical Plantation Journal, 2022
The basic concept of organic farming prevents synthetic chemical compounds from using fertilizers, pesticides, and growth regulators. Natural insecticides are alternative pesticides in pest control on plants because they are available around us and have a good impact on the sustainability of the agricultural environment.
