Embodiment 1

[0024] The weight percent of the water agent for controlling the spider mite is: 1% of compound plant extract, 99% of distilled water.

[0025] Weigh gallnut, Chinese prickly ash stem, leaf or fruit, holly holly stem or leaf and potato stem or leaf powder (20 mesh particles) each 20g, soak 1-3 days at room temperature with 70% ethanol solution 800ml, filter, take four The filtrate of the plant is concentrated under reduced pressure to recover the solvent to obtain an extraction extract, and a certain amount of distilled water is added, placed in an ultrasonic generator for 10-15 minutes to suspend the dry matter, and prepared into an aqueous solution with a concentration of 1%.

[0026] experiment method:

[0027] The determination of the activity of the compound botanical acaricide against Tetranychus cinnabarinus was carried out according to the method of soaking the stems of spider mites in the Bioassay SOP of the National Southern Pesticide Innovation Center. The compound...

Embodiment 2

[0029] The weight percent of the water agent for controlling the spider mite cinnabarinus: 3% of compound plant extract, 97% of distilled water.

[0030] Weigh gallnuts, pepper stems, leaves or fruits, holly stems or leaves, and potato stems or leaf powder (20 mesh particles) each 50g, soak 1-3 days at room temperature with 70% ethanol solution 2000ml, filter, take The filtrate was concentrated under reduced pressure to recover the solvent to obtain the extract extract, and a certain amount of distilled water was added, placed in an ultrasonic generator for 15 minutes to suspend the dry matter, and prepared into an aqueous solution with a concentration of 3%. The indoor pot method was used for biotesting of cucumber aphid, and the mortality rate was counted after 24 hours, and the control effect was 100%.

Embodiment 3

[0032] The weight percent of the water agent for controlling the spider mite is: 2% of the compound plant extract and 98% of distilled water.

[0033] Weigh gallnuts, pepper stems, leaves or fruits, holly stems or leaves, and potato stems or leaf powder (20 mesh particles) each 50g, soak 1-3 days at room temperature with 70% ethanol solution 2000ml, filter, take The filtrate was concentrated under reduced pressure to recover the solvent to obtain the extract extract, and a certain amount of distilled water was added, placed in an ultrasonic generator for 15 minutes to suspend the dry matter, and prepared into an aqueous solution with a concentration of 2%. Respectively extract five times with equal volumes of sherwood oil, ethyl acetate, n-butanol successively; Wherein sherwood oil, ethyl acetate, n-butanol extract and the water suspension after extraction are concentrated to dryness under reduced pressure respectively, The obtained compound plant extract was dissolved in deio...

Abstract

The invention relates to a compound plant-source acaricide and a preparation method thereof, relating to the technical field of farm chemical. The acaricide comprises the following components based on percentages by weight: 5-40% of nutgall extract, 5-40% of wild pepper extract, 2-30% of pubescent holly root extract, 2-30% of potato extract and 20-60% of distilled water. The invention has the advantages of effectiveness, no residue, wide range, low production cost, economy, practicability and environment protection.

Description

technical field [0001] The invention relates to an acaricide in the technical field of pesticides and its preparation, in particular to a compound botanical acaricide and a preparation method thereof. Background technique [0002] In recent years, due to the irrational use of chemical pesticides and the inherent shortcomings of the pesticides themselves, a series of public hazards have arisen in the use of pesticides, such as environmental pollution, human and animal poisoning, killing natural enemies, destroying ecological balance, "3R" (Residue , Resistance, Resurgence) and other serious problems, these adverse effects have aroused widespread concern. On the other hand, the success rate of synthetic pesticide development is low, the cycle is long, and the cost is astonishing. Due to the above reasons, when the pesticide industry in various countries in the world is looking for new bio-rational pesticides, they turn their attention to bio-rational pesticides that are highl...
