Many gardeners use dry mustard to scare off harmful insects in the yard. An infusion is prepared from it and added to various mixtures. It is completely safe and ecological for the environment, but it works no less effectively than any chemical preparations. And it is also cheap, accessible and useful.
Use of dry mustard against pests in the garden
Correct use of dry mustard
Using dry mustard powder has a much longer shelf life than diluted and infused with water. In dry weather, mustard powder can last on plants for 7-8 days, and sometimes up to 2 weeks.
An aqueous solution based on mustard powder is applied to the plants in the morning or at the end of the day, when the sun sets or on cloudy days, so as not to burn the leaves of the plants.
