Abstract
An accurate controlled-release strategy of pesticides is considered desirable in sustainable agriculture. A site-specific nanorelease system of dazomet (DZ) was proposed by employing the zeolitic imidazolate framework-8 composite (DZ@ZIF-8) by a one-pot method. The synthetic parameters of DZ@ZIF-8 were optimized, and the loading content of DZ was maximized. ZIF-8 endowed DZ with a pH-sensitive behavior. The collapse of the DZ@ZIF-8 structure and the site-specific release of DZ were triggered by acidic substances produced by Botrytis cinerea. In vitro and pot experiments showed that the fungicidal activity of DZ@ZIF-8 was about 36.3 and 42.7% higher than that of DZ, respectively. DZ is conventionally used before a crop is planted because of its volatility and toxicity. However, DZ@ZIF-8 could avoid phytotoxicity of DZ to plants, which made the application of DZ possible during plant growth. Moreover, the acute toxicity to zebrafish changed from high to moderate levels. This study highlights a potential strategy that improves DZ effective utilization and reduces side effects.
