Description

Technical Field

[0001] The present application relates to the field of plant protection technology, and in particular to a penetrating composition, an insecticide composition and applications thereof. Background Art

[0002] Stem-boring pests (including longhorn beetles, jewel beetles, wood borers, bark beetles, stem wasps, and weevils) infect plants by feeding on them as larvae within branches and trunks. Except for the adult stage, which is exposed, all other stages (eggs, larvae, and pupae) remain hidden within the phloem and xylem. While difficult to detect in the early stages of an infestation, serious damage is already inflicted once symptoms appear. Because stem-boring pests spend most of their time inside plant tissues, they are less susceptible to external influences, have few natural enemies, and maintain a relatively stable population density.

[0003] Stem-boring insects, also known as heart borers, are a major threat to trees. In mild cases, the transport of nutrients and water is hindered, while in severe cases, branches and trunks are riddled with holes, withering and dying or being blown away by the wind. For a long time, stem-boring insects have severely harmed tree growth, causing devastating losses to species.

[0004] Plant vascular diseases, such as wilt, verticillium wilt, and yellow dragon disease, are typical soil-borne, vascular, and fungal diseases. They are difficult to prevent and control crop diseases and are therefore called "cancer" diseases.

[0005] Trunk-boring pests and vascular diseases attack the tree's vascular system, making it difficult for conventional pesticides to reach these affected areas. Traditional control methods involve drilling holes in the tree or scraping the bones to heal the wound, which can cause secondary damage to the tree, is ineffective, and wastes significant manpower and resources. To ensure insecticide penetration into the affected areas, a large number of penetrants are being used. However, most penetrants currently on the market contain silicone or essential oils, which only penetrate the stems and leaves of herbaceous plants or the leaves of woody plants relatively well, but have almost no penetration into the trunks of woody plants. Furthermore, the silicone production process is complex and poses significant environmental risks. Summary of the Invention

[0051] It should be noted that all formulations were stored at 4°C without crystallization, and a hot storage test (stored at 54°C for 14 days) showed no change in appearance.

[0052] In some embodiments, the osmotic composition is prepared by the following steps:

[0053] Add the penetrant, adjuvant and solvent into a reaction kettle and stir at 2500-3000 rpm / min at 37-40° C. to obtain a reagent mixture;

[0054] The surfactant is added to the reagent mixture and stirred at a speed of 2500-3000 rpm / min to prepare the penetration composition.

[0055] For example, the penetrant, adjuvant and solvent are placed in a reaction kettle, stirred at 3000 rpm / min at 37-40°C for 10-15 minutes, and then the surfactant is added and stirred at 2500 rpm / min for 5 minutes to prepare a finished product, i.e., the penetrant composition.

[0056] The penetration composition of the present application has strong penetration power and can penetrate the trunks of woody plants, which helps to transport the drug to the diseased area and effectively prevent and control diseases such as pests or fungal infections; at the same time, it is easy to prepare and use.

[0061] Mixing an insecticide with a penetrating composition produces an insecticidal composition that, through the penetrating composition, facilitates the delivery of the insecticide to the vascular bundles of trees, effectively controlling tree-boring pests. Mixing a fungicide with a penetrating composition produces an insecticidal composition that, through the penetrating composition, facilitates the delivery of the fungicide to the vascular bundles of trees, effectively controlling bacterial or fungal infections of trees.

[0062] It should be noted that the two types of insecticide compositions prepared by using insecticides or fungicides can be used together to simultaneously control pests and bacteria or fungi.

[0063] The insecticide composition of the present application has strong penetrating power and can penetrate the trunks of woody plants, which helps to transport the drug to the diseased area and effectively prevent and control diseases such as pests or fungal infections; at the same time, it is easy to prepare and use. Through the use of penetrants, the dosage of the drug can be reduced, economic costs can be saved, the impact on the environment can be reduced, it is safer for humans and animals, and the risk of pests developing resistance to the drug is reduced.

[0064] The following is a more detailed description of the present application with reference to specific embodiments, and further elaboration of the present application. However, these embodiments are by no means intended to limit the present application.

[0065] Example 1

[0066] Poplars, a native species in northern my country, are drought-tolerant, barren-resistant, heat-resistant, and cold-resistant, and they grow rapidly. They play a vital role in preventing wind damage and managing the ecology of sandy areas. However, in recent years, longhorn beetles have severely damaged poplar shelterbelts, causing the degradation of poplar shelterbelts. Among them, Anoplophara glabripennis, Apriona germari, and Batocera hosfieldi are the main species that harm poplars. In addition to poplars, these longhorn beetles host nearly 40 plant species, including willow, elm, mulberry, and maple, covering virtually all tree species in my country's northern shelterbelts. In addition to directly harming major shelterbelts like poplar and willow, the pine mushroom Monochamus alternatus also spreads pine wood nematodes into pine trees, causing pine diseases. Pine trees infected with pine wood nematodes develop yellow-brown or reddish-brown needles, wilt and droop, and resin secretion ceases. The entire tree withers and dies, eventually rotting.

[0067] This embodiment is a longhorn beetle experiment. The test site is located in Hejing County, Xinjiang Uygur Autonomous Region. The tree species are poplars, 9 to 12 years old, with an average tree height of 12 to 15 meters and a breast diameter of 11 to 13 cm. The trees grow in a uniform manner, and longhorn beetles are found on the trunks of the trees.

[0068] Test method:

[0069] Dilute the penetrating composition 60 times and the pesticide 50 times. Spray evenly on the trunk of each tree within 3 meters of the test area until water drips. Spray on a clear, windless day with no rain within 8 hours of spraying.

[0070] Result statistics: Take a position 4 meters above the ground, each section is 50 cm, and there are 8 sections in total. Count the number of insect deaths at each age after spraying. Take 5 plants from each experimental group for statistics. The experimental results are shown in Tables 4 to 8.

[0094]

[0095] The above experimental results show that the experimental groups added with the penetrating composition have a good contact killing effect on the longhorn beetle larvae, and the insect population reduction rate is more than 85%.

[0096] Example 2

[0097] This example is an experiment on Huanglongbing disease in navel orange.

[0098] Test location: The test site was set up in Huichang County, Ganzhou City, Jiangxi Province. The navel orange trees were 6 years old, with uniform growth and obvious Huanglongbing disease.

[0099] Test method: Mix the pesticides listed in Table 9 below and spray evenly on the surface of navel orange leaves, trying to spray all leaves evenly.

[0100] Table 9

[0101] Element concentration Ferrous sulfate 50ppm Manganese sulfate 65ppm zinc sulfate 50ppm tetracycline 100ppm Nanosilver 5ppm Penetration composition 200-fold dilution

[0102] There were four control groups, including spraying tetracycline alone, spraying the penetrating composition alone, spraying water alone, and spraying each component except the penetrating composition. Each group was sprayed with 50 plants.

[0103] Result statistics: The results were judged visually based on whether the normal growth had been restored. The specific experimental results are shown in Table 10.

[0104] Table 10 Experimental results

[0105]

[0106] The experimental group began to shed leaves the day after spraying, with each tree shedding 23-35 leaves. The control group, which was only sprayed with water, only lost one or two leaves sporadically, while the group sprayed with the penetrating composition alone lost about 15-25 leaves. This leaf-shedding state lasted for 12 days. The amount of leaves lost in the experimental group accounted for 19% of the entire tree, indicating that the penetrating composition had been transmitted to the vascular bundle.

[0107] After 12 days, leaf drop stopped. After 18 days, a small number of leaves in the experimental group turned dark green from yellow. This change was due to the absorption of the metal ions iron by the new leaves. New leaves began to grow after 35 days, and after 50 days, clusters of new leaves emerged. These new leaves began to resemble normal leaves (normal leaves: 2-4cm x 4-8cm, leaves with Huanglongbing: 1-2cm x 2-5cm). There was no yellowing around the vascular bundles, indicating that other metal ions had been absorbed. After 80 days, the trees looked indistinguishable from normal navel orange trees. In addition to the aboveground parts, new white roots were visible when the underground parts were dug up. In the control group, no new white roots were found, and the roots showed signs of rot and withering.

[0108] In summary, the insecticide composition of the present application has strong penetration through the use of penetrants, can penetrate the trunks of woody plants, helps to transport the drug to the diseased parts, and effectively prevents and controls diseases such as pests or fungal infections.

[0109] Obviously, the embodiments described above are only some of the embodiments of the present application, rather than all of the embodiments. The preferred embodiments of the present application are given in the specification, but they do not limit the patent scope of the present application. The present application can be implemented in many different forms. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present application more thorough and comprehensive. Although the present application has been described in detail with reference to the aforementioned embodiments, for those skilled in the art, it is still possible to modify the technical solutions described in the aforementioned specific embodiments, or to make equivalent replacements for some of the technical features therein.
