Problems solved by technology

[0003] Commonly used root-knot nematode agricultural control measures in production include: ① Cultivate excellent seedlings: For example, root-knot nematode-resistant tomato varieties mainly include Liaofen No. 2, Qianxi and Difenni, etc.; ② Physical control: water flooding treatment and high temperature treatment Sheds, etc.; ③Chemical control: including fumigants such as sulfuryl fluoride, calcium cyanamide and metabam, and non-fumigant agents such as fluopyram, carbofuran and methimphos; ④Biological control: currently commercial Plant-derived pesticides with nematicidal activity mainly include azadirachtin, matrine, veratrine, and scopolamine, etc., and there are relatively few types. The microorganisms used to prevent and control root-knot nematode diseases within the validity period of registration in my country include Lavender. Penicillium, Verticillium chlamydia, Bacillus firmus and Bacillus cereus, however, the effectiveness of biocontrol microorganisms is greatly affected by the environment

Embodiment

[0016] (1) Clean the whole plant of Breaking Bowl Flower, Deer vine root, Chrysanthemum chrysanthemum leaves, Licewort and Houttuynia cordata, dry in a blast drying oven at 45°C until constant weight, and crush with a multifunctional pulverizer , through a 60-mesh sieve, and set aside;

[0017] (2) Take 5g of the broken bowl flower flower, deer vine root, chrysanthemum leaf, lice grass and houttuynia cordata powder prepared in step (1) and add them to the triangular flask according to the mass ratio of 4:5:3:3:2, and add 100mL of distilled water, placed on a shaker for 12h, rotating speed 180r / min, temperature 35°C, filtered with gauze to obtain the mother liquor of compound insecticide, the concentration is recorded as 50g / L;

[0018] (3) Dilute the mother liquor prepared in step (2) in order to obtain 12.5g / L, 6.25g / L, 3.125g / L, 1.5625g / L, 0.78125g / L, and place in a 4°C refrigerator for later use.

Abstract

The invention belongs to the technical field of botanical pesticides, and discloses a botanical compounded insecticide for root-knot nematode incognita and a preparation method thereof. The water extract of chrysanthemum chrysanthemum, lice grass water extract and Houttuynia cordata water extract, the present invention realizes the synergistic effect of killing root-knot nematodes by compounding various plant extracts, shortening the time of killing insects, It can effectively increase the mortality of pests while reducing the amount of pesticides. Moreover, only neutral distilled water needs to be used as the extractant in the preparation process, which saves cost and is easy to operate.

Description

technical field [0001] The invention belongs to the technical field of botanical pesticides, and in particular relates to a botanical compound insecticide for root-knot nematode incognita and a preparation method thereof. Background technique [0002] Root-knot nematode (Meloidogyne spp.) is a kind of plant parasitic nematode that causes serious loss of agricultural production in the world. Cucurbitaceae and Brassicaceae root-knot nematodes are particularly serious. Among them, root-knot nematode incognita is the most harmful. After the disease occurs, it will generally cause a 10% to 20% yield reduction, and the serious one can reach more than 75%. According to incomplete statistics, the damage caused by root-knot nematode in the world can reduce the world's agricultural output by 24.5% every year on average, which brings great economic losses to agricultural producers. [0003] Commonly used root-knot nematode agricultural control measures in production include: ① Cultiv...
