Application effect of water-resistant film-forming agent ZY904 for seed coating

doi:10.11924/j.issn.1000-6850.casb18120023

Abstract

Abstract: In this research, the application of film-forming agent on rice seed coating was evaluated by measuring the physical and chemical properties and application performance indexes of water-resistant film-forming additives ZY904-1, ZY904-2 and ZY904-3. The purpose is to screen out the film-forming agent and the added concentration which can significantly improve the sustained-release properties of pesticides.The high performance liquid chromatography method was used to quantitatively determine the pesticide retention rate at different time points after soaking.The results showed that the filming agent ZY904-2 had a coating uniformity of 95.7% and a coating shedding rate of 1.7% at an additive concentration of 0.5%. The growth rate of germination and germination rate was 1.25% and 3.23% compared with the control, plant height and root length increased by 0.52 and 0.62 cm, respectively.The overground dry weight and underground dry weight increased by 0.46 g and 0.33 g, respectively. After 40 d of water immersion, the azoxystrobin retention rate could still reach 47.26%. The film-forming agent ZY904-2 can promote the growth of plants after application to rice seed coating agent, and significantly improve the sustained release property of azoxystrobin. It is recommended to be applied in the research and development of rice seed coating agents.
