Summary
Oxazosulfyl is a new insecticide effective against major rice pests. It offers a novel mode of action and controls resistant insect populations, supporting sustainable agriculture.
Area of Science:
- Agricultural Science
- Entomology
- Pest Management
Background:
- Insecticide resistance poses a significant threat to global food security.
- Novel chemical classes and modes of action are crucial for effective pest management.
- The sulfyl group represents a new chemical class of insecticides.
Purpose of the Study:
- To introduce oxazosulfyl, a novel insecticide.
- To evaluate its efficacy against major rice insect pests.
- To assess its potential in managing insecticide resistance.
Main Methods:
- Field studies in rice paddy environments.
- Evaluation of efficacy against Coleoptera, Hemiptera, Lepidoptera, and Orthoptera.
- Assessment of control against insect populations with reduced sensitivity to existing insecticides.
Main Results:
- Oxazosulfyl demonstrated excellent control of major rice insect pests.
- It proved highly effective against insect populations resistant to conventional insecticides.
- Registered as ALLES® granules in Japan in April 2021.
Conclusions:
- Oxazosulfyl is a novel vesicular acetylcholine transporter inhibitor (IRAC Group 37).
- It offers a new solution for managing insecticide resistance in rice pests.
- Expected to contribute to sustainable agriculture through reduced chemical use and labor savings.

In ozonolysis, ozone is used to cleave a carbon–carbon double bond to form aldehydes and ketones, or carboxylic acids, depending on the work-up.
Ozone is a symmetrical bent molecule stabilized by a resonance structure.

01:11Aryldiazonium Salts to Azo Dyes: Diazo Coupling
3.1K
The reaction of weakly electrophilic aryldiazonium (also called arenediazonium) salts with highly activated aromatic compounds leads to the formation of products with an —N=N— link, called an azo linkage. This reaction, presented in Figure 1, is known as diazo coupling and occurs without the loss of the nitrogen atoms of the aryldiazonium salt. Highly activated aromatic compounds such as phenols or arylamines favor the diazo coupling reaction. The coupling generally occurs at the...
