AI Technical Summary

Technical Problem

There are currently no reports on the preparation of juglone into microemulsions for use in pesticides. Traditional chemical pesticides pose environmental pollution and toxicity problems, necessitating the development of environmentally friendly and low-toxicity green pesticide formulations.

Method used

Juglone was used as the insecticidal active ingredient and combined with environmentally friendly additives to prepare an O/W type microemulsion, which included juglone, oil phase, emulsifier, co-emulsifier and water. The component ratio was optimized and the best combination was selected through pseudo ternary phase diagram and response surface design during the preparation process.

Benefits of technology

The prepared juglone microemulsion is a clear and stable liquid, which improves the solubility and dispersibility of juglone, reduces the amount used, has a good insecticidal effect, is environmentally friendly, and prevents pests from developing resistance.

Abstract

The invention belongs to the technical field of botanical pesticides, and particularly relates to a preparation method and insecticidal activity of juglone microemulsion. The juglone microemulsion comprises the following components in percentage by mass: 2.5 to 10 percent of juglone, 5 to 25 percent of oil phase, 5 to 15 percent of emulsifier, 5 to 35 percent of co-emulsifier and the balance of water. The mass ratio of the emulsifier to the co-emulsifier is (1: 0.5)-(1: 3). According to the juglone microemulsion disclosed by the invention, plant-derived juglone is taken as a main drug, and the prepared juglone microemulsion is an O / W type microemulsion, is brown, clear and stable liquid, and can be directly sprayed on leaf surfaces of crops after being diluted, so that the effects of killing and expelling insects are achieved.
