Abstract

The invention provides compound composition containing eugenol and mustard essential oil which are plant-sourced active substances with environmental compatibility and mixed in a weight ratio being (1:10)-(10:1), preferably in a weight ratio being (1:4)-(4:1). The compound composition has an obvious synergic effect, can be prepared in a form such as microemulsion, emulsion in water, water dispersible granules and the like and is used for controlling plant fungal diseases, bacteriosis, virus diseases and the like, so that the control effect is improved, the dosage is reduced, the application times are reduced, the control range is enlarged, the resistance is delayed, the requirement of a conventional dose reduction application technology is met, and the prepared preparation is environmentally friendly and has good application prospect.

Description

technical field [0001] The invention belongs to a pesticide compound composition for preventing and treating fungal diseases, bacterial diseases and viral diseases of crops, and in particular relates to a compound agent of plant source eugenol and mustard essential oil and its application. Background technique [0002] Eugenol (4-allyl-2-methoxyphenol) is the main component of plant clove and clove basil extract clove basil oil, which has pharmacological effects such as antibacterial, anti-inflammatory, antipyretic, anesthetic, antiseptic, and mosquito repellent. There are many research applications in the field of medicine. In recent years, studies have found that eugenol, which is used in the prevention and control of agricultural diseases, has good bactericidal and antiviral effects, and is highly efficient, low-toxic, pollution-free, non-residual, does not pollute the environment, and does not affect the quality of agricultural products. [0003] Mustard essential oil i...
