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 high-efficiency scale insecticide, including the extracts of Rhizoma chinensis, extracts of hellebore, extracts of hives, extracts of gourd tea, extracts of Qumai, extracts of green bark, extracts of xuejianchou, and extracts of bark , Houttuynia cordata extract and azadirachtin, the components are as follows:

[0024]

[0025]

[0026] Its preparation method: add water to decoct Guanzhong, Veratrum, and honeycomb twice, 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 is decompressed Concentrate to a relative density of about 1.15, and prepare the liquid medicine for later use; decoct gourd tea, Qumai, Qingpi, Xuejianshou, Qinpi, and Houttuynia cordata with water for two times, each time for 1 hour, combine the decoction, filter, concentrate the filtrate, and put Cool, add ethanol to make the ethanol content 6...

Embodiment 2

[0029] This example verifies the killing rate of the pharmaceutical composition on scale insects 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] Group according to different insecticides, each group prepares 1000 scale insects in the three stages of eggs, larvae and adults, and then uses insecticides on the scale insects in each stage, and tests each group of insecticides kill rate, as shown in the table below:

[0032] Table 1 The killing effect of insecticides on scale insects

[0033]

[0034] It can be seen from the above table that each group of insecticides has the highest killing rate on scale insects in the larval state, and this product has the best insecticidal effect, and the killing effect is remarkable, even the eggs that are most difficult to kill also have a good killing effect .

Embodiment 3

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

[0037] Select 10,000 scarabs, beetles, mole crickets, borer worms, pear psyllids, scale insects, spodoptera, leafhoppers, vetch, and root-knot nematodes, and group them respectively, and use the drugs prepared in Example 1 to make drugs with 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 scale insects, and has a very limited killing effect on other pests. This proves that this product is highly targeted and can only be used For the extermination of scale insects.

Abstract

The invention discloses a high-efficiency scale insect killer, which is prepared from a cyrtomium rhizome extract, a radix et rhizoma veratri extract, a honeybee hive extract, a triquetrous tadehagi herb extract, a pink herb extract, a green tangerine peel extract, a herba teucrii viscidi extract, a cortex fraxini extract, a herba houttuyniae extract and azadirachtin. The high-efficiency scale insect killer can be used for killing scale insects in a targeted way, and is free from any side or toxic effects on natural enemies of the scale insects; the high-efficiency scale insect killer is goodin safety and biodegradation as well as free from pollution, pungent smell and environmental toxicity, and does not leaves residues in animals, thus not destroying the ecological balance and being little in effect on a crop growth environment; the high-efficiency scale insect killer has better permeability and wettability, can interfere with the nervous system of insect bodies, inhibits the synthesis and development of eggs, and does not easily cause drug resistance; the high-efficiency scale insect killer is good in fast-acting property, thus being suitable for being widely popularized and applied to the aspect of pest control and prevention.

Description

technical field [0001] The invention belongs to the field of agricultural technology development, and in particular relates to a high-efficiency scale insecticide. 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 suitable, and most farmers st...
