Problems solved by technology

[0004] In order to obtain stevia with high quality and good commercial value, we must pay attention to the impact of insect pests. At present, when people control stevia pests, they generally use high-concentration pesticides to kill them. Although they can have a therapeutic effect, they will cause environmental damage. Pollution can also cause harm to the human body, and excessive dosage will affect stevia plants, such as burning seedlings and other symptoms. Therefore, research and development can effectively prevent the impact of insect pests in the growth process of stevia, and has environmental performance. Insecticide has important significance and application value

Abstract

The invention provides an insect-resisting insecticide for stevia rebaudiana planting and a preparation method. The insecticide is prepared from the following components: stevia rebaudiana straw, radix sophorae flavescentis, radix euphorbiae ebracteolatae, melia azedarach leaves, kadsura root-bark, rhizoma atractylodis, herba artemisiae annuae, radix glycyrrhizae, flos lonicerae, pyrethrum cinerariifolium, fructus capsici, rhizoma acori tatarinowii, rhizoma coptidis and radix stemonae. The preparation method comprises the following steps: weighing the radix sophorae flavescentis, the radix euphorbiae ebracteolatae, the melia azedarach leaves, the kadsura root-bark, the rhizoma atractylodis, the herba artemisiae annuae, the radix glycyrrhizae, the flos lonicerae, the pyrethrum cinerariifolium, the rhizoma acori tatarinowii and the radix stemonae according to the proportion, adding water for decoction, and performing cooling and filtering; decocting filter residues again, performing filtering twice, and mixing obtained filtrate; weighing and mashing fresh fructus capsici, the stevia rebaudiana straw and the rhizome coptidis to obtain juice according to the proportion respectively; mixing the filtrate and the juice to obtain the insecticide. The insect-resisting insecticide can be used for effectively preventing the influence of insect pests in a growth process of the stevia rebaudiana so as to obtain the stevia rebaudiana with high nutritional value and high quality, is suitable for vast farmers to select and use, and has relatively higher application value and environmental protection significance.

Description

Technical field [0001] The invention relates to the technical field of agricultural disease and insect control, in particular to a stevia planting insecticide and a preparation method. Background technique [0002] Stevia is a perennial perennial herb of the Asteraceae family, and its origin is in the subtropical regions of South America. The roots, stems and leaves of stevia contain stevioside. Steviol glycosides have the characteristics of high sweetness (200 to 300 times that of sucrose), low calories (only 1 / 300 of sucrose), and have the effects of raising blood sugar, lowering blood pressure, and promoting metabolism. It is effective for obesity, diabetes, Heart disease, dental caries, etc. have a certain auxiliary effect, which has attracted people's attention and attention, becoming the "third sugar source" after sucrose and synthetic sugar. [0003] The planting area of ​​stevia is also expanding, and the supply exceeds demand. Stevia products are widely used in medicine...
