Example Embodiment

[0022] Example 1:

[0023] This embodiment provides a good penetrating psyllid killer, which includes morning glory seed extract, saponum extract, crane louse extract, calamus extract, yellow bark root extract, scutellaria extract, banyan tree beard The components of extract, chamaejasme extract, yellow fruit extract and diazinon are as follows:

[0024]

[0025]

[0026] Its preparation method: decocting the morning glory seed, soap alum and crane louse with water twice for 2 hours each time, combine the decoction, add ethanol to filter and concentrate, add 3 times the amount of water, fully stir, refrigerate for 48 hours, filter, and reduce the filtrate Press and concentrate to a relative density of about 1.15, and use the liquid medicine for later use; add water to decocting two times, 1 hour each time, and then combine the decoction and filter. Concentrate the filtrate, let it cool, add ethanol to make the ethanol content 65%, let stand overnight, filter, and concentrate the f...

Example Embodiment

[0028] Example 2:

[0029] This example verifies the killing rate of the pharmaceutical composition against Psylla psyllus compared with common insecticides in the market.

[0030] Choose common insecticides on the market: Porphyridium lavender water, nematicides, specific root nematodes, thiamethoxam insecticides.

[0031] According to different insecticides, each group prepares 1000 psyllids each in the three stages of eggs, larvae, and adults, and then uses insecticides on each stage of psyllids to test each group of insecticides The killing rate is as shown in the following table:

[0032] Table 1 The killing effect of insecticides on psyllids

[0033]

[0034] It can be seen from the above table that each group of insecticides has the highest killing rate on the larval psyllids. This product has the best insecticidal effect, and the killing effect is significant. Even the most difficult to kill eggs has a good killing effect. .

Example Embodiment

[0035] Example 3:

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

[0037] Select 10,000 psyllids, beetles, mole crickets, heartworms, scarabs, scale insects, worms, leafhoppers, mud worms, root-knot nematodes, respectively, and group them into groups, and use the medicine prepared in Example 1 to make the same concentration of medicine Spray the pests in each group separately. 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] It can be seen from the above table that the medicine prepared in Example 1 only has a good killing effect on Psylla sylvestris, but has very limited killing effect on other pests. This proves that this product is highly targeted and can only be used It is used to kill the pear lice.

Abstract

The invention discloses a psylla chinensis killing agent with high permeability. The psylla chinensis killing agent is prepared from a semen pharbitidis extract, a melanterite extract, a common carpesium fruit extract, a radix flemingiae extract, a wampee root extract, a semen raphani extract, a ficus microcarpa extract, a radix euphorbiae lantu extract, a solanum xanthocarpum extract and diazinon. The pharmaceutical composition disclosed by the invention can be used for specifically killing psylla chinensis, has the advantages of freeness from toxic and side effects on natural enemies of thepsylla chinensis, high safety, high biodegradability, freeness from pollution and pungent smell, freeness from environmental toxicity, no residues in animals, no damage to biological balance, low influence on the crop growing environment, higher permeability, higher moistening property, capabilities of interfering the central nervous system of the psylla chinensis and restraining synthetic development of worm eggs, non-tendency to pesticide resistance and high fast-acting property, and is suitable for being widely popularized and applied on the aspect of pest prevention and control.

Description

technical field [0001] The invention belongs to the field of agricultural technology development, and in particular relates to an exterminating agent for pear psyllids with good permeability. 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 resolved. 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 s...
