Problems solved by technology

However, when this kind of chemical pesticide is promoting green and protecting the environment today, many highly toxic and high residue chemicals have been limited or discontinued. In addition, due to the different types of pests, various pests have different levels of pesticide resistance and resistance. There are large differences, so that the insecticidal effect of chemical agents is prone to drug-resistant pests, so it is necessary to propose insect repellents for different insects to prevent specific insects, but there is no corresponding report so far

Embodiment 1

[0023] This example provides a pharmaceutical composition for killing root-knot nematodes, including pumpkin seed extract, arsenic stone extract, morning glory seed extract, radish extract, radish seed extract, chamaejasma chamaejasme extract, tiger’s leg extract Extract, Boa Bougainvillea Extract, Ficus Barbadensis Extract and Veratrine in the following quantities:

[0024]

[0025]

[0026] Its preparation method: decoct pumpkin seeds, arsenic stones, and morning glory seeds twice with water, each time for 2 hours, combine the decoction, add ethanol to filter and concentrate, add 3 times the amount of water, fully stir, refrigerate for 48 hours, filter, and the filtrate reduces Concentrate under pressure until the relative density is about 1.15, and prepare the medicinal solution for later use; add radish, radish, chamaejasma chamaejasme, tiger's leg, anaconda, and banyan to decoct twice, each time for 1 hour, combine the decoction, filter, and concentrate Let the filt...

Embodiment 2

[0029] This example verifies the killing rate of root-knot nematodes of the pharmaceutical composition compared with common insecticides on the market.

[0030] Select the common insecticides on the market: P. lilacinus water agent, nematicide, special root thread agent, and thiamethoxam insecticide.

[0031] Grouping according to different insecticides, each group prepares 1000 root-knot nematodes in the three stages of eggs, larvae, and adults respectively, and then uses insecticides on the root-knot nematodes in each stage respectively, and tests each group to kill the root-knot nematodes. Insecticide kill rate, as shown in the table below:

[0032] Table 1 The killing effect of insecticides on root-knot nematodes

[0033]

[0034] It can be seen from the above table that each group of insecticides has the highest killing rate on root-knot nematodes in the larval state, and this product has the best insecticidal effect, and the killing effect is remarkable, and it can k...

Embodiment 3

[0036] This example verifies the killing rate of the pharmaceutical composition on various pests.

[0037] Select 10,000 scarabs, beetles, leafhoppers, borers, pear psyllids, scale insects, spodoptera, mole crickets, vetch, and root-knot nematodes, and group them respectively, and use the medicines prepared in Example 1 to make medicines of the same concentration. liquid, spray the pests of each group respectively, and after 1 hour, check the killing rate of various pests, the results are shown in the following table:

[0038] Table 2 The killing effect of the drug on various pests

[0039] group

[0040] As can be seen from the above table, the medicine prepared in Example 1 only has a good killing effect on root-knot nematodes, and has a very limited killing effect on other pests. This proves that this product is highly targeted and can only be used to kill root-knot nematodes. Used for killing root-knot nematodes.

Abstract

The invention discloses a pesticidal composition for killing root-knot nematode. The pesticidal composition comprises a pumpkin seed extract, an arsenolite extract, a semen pharbitidis extract, a radish stem-and-leaf extract, a radish seed extract, a Stellera chamaejasme extract, a Polygonum perfoliatum extract, a Caesalpinia minax extract, a Ficus microcarpa extract and veratridine. The pesticidal composition provided by the invention has the following advantages: capability of targetedly killing the root-knot nematode, no toxic and side effects to natural enemies of the root-knot nematode, good safety, good biodegradation, no pollution and irritating odor, no environmental toxicity, no residues in animals, no damage to ecological balance, little influence on the growth environment of crops, good permeability and wettability, interference to the central nervous system of a midge body, inhibition of combination and development of midge eggs, insusceptibility to generation of pesticideresistance, good fast-acting property, and applicability to extensive popularization and application in the fields of prevention and treatment of pests.

Description

technical field [0001] The invention belongs to the field of agricultural technology development, and in particular relates to a medicinal composition for killing root-knot nematodes. Background technique [0002] Chemical agents play an important role in the control of crop diseases and insect pests, but the residues of drugs lead to the deterioration of natural ecosystems, which has become a major issue of international concern and urgently to be solved. In our country, since the 20th century, due to the single use of chemical pesticides, the harmful elements in agricultural products have exceeded the standard, which directly endangers the health and survival of the people. For this reason, the country attaches great importance to and formulated the "Medium and Long-term Science and Technology Development Program Outline" to encourage research and development Environmentally friendly fertilizers and pesticides. Today's farmers' "seeking speed" mentality is not suitable, a...
