Description

Combined medicine for protecting plants from damage of rhynchophorus ferrugineus

Technical Field

The invention belongs to the field of plant protection, relates to a plant protection pharmaceutical composition, and particularly relates to a combined medicament for protecting palmaceae plants from being harmed by rhynchophorus ferrugineus.

Background

The rhynchophorus ferrugineus is an international quarantine pest, is listed in the entry plant quarantine pest list and the forestry quarantine pest list in China, and is mainly harmful to palmae plants, such as coconut, betel nut, oil palm and other palm crops. The insect mainly takes soft tissues eaten by the larvae which are borer stems from the crowns as pests, often outbreaks and disasters occur in newly introduced areas, the damage has the characteristics of concealment and lethality, the damage to adult plants is serious, and particularly under the condition that plant wounds are caused by palm fruit harvesting, typhoon, branch and leaf pruning and the like, the red palm weevil can rapidly invade a tree body through the wounds to cause damage to the plants.

At present, the prevention and treatment of the red palm weevil are mainly chemical prevention and physical prevention, the chemical prevention and treatment mainly adopts medicines for medicine application prevention and treatment, the physical prevention and treatment mainly comprises trap trapping, artificial mechanical trapping and the like, and the good prevention effect can be achieved, but the research on preventing the red palm weevil from damaging plants and protecting the wounds from further deterioration is less under the condition that the plants have wounds. Through retrieval, no report about a medicament for protecting plant wounds from being damaged by the rhynchophorus ferrugineus is found.

Disclosure of Invention

The invention aims to provide a combined medicine for protecting plants from being damaged by rhynchophorus ferrugineus, which has the advantages that all components act together, the plant damage by the rhynchophorus ferrugineus is prevented, wounds are protected from further deterioration, tree vigor is improved, the purpose of complementation of different effects is achieved, the medicine cost is reduced, and the prevention and treatment effect is improved.

The technical scheme adopted by the invention is as follows:

a combined medicine for protecting plants from being damaged by rhynchophorus ferrugineus is prepared by mixing chlorantraniliprole, kasugamycin, hydroxyolefine adenine and amino acid, wherein the contents of the components in percentage by mass are as follows: 25-40% of chlorantraniliprole, 30-45% of kasugamycin, 10-15% of hydroxyeneadenine and 10-20% of amino acid, wherein the sum of the mass percentages of the components is one hundred percent.

In the invention, the amino acid is one or a mixture of more of cysteine, phenylalanine, alanine, methionine, glycine, glutamic acid, arginine, lysine, tyrosine, leucine, proline, tryptophan, serine, threonine, aspartic acid, valine, isoleucine and histidine.

In the invention, the conventional auxiliary materials in the pesticide processing process are added into the combined medicine to prepare conventional formulations, including granules, water aqua, smearing agent, powder, emulsion and the like.

The combined medicine provided by the invention is applied to the wounds of the palmaceae plants after being prepared into a conventional dosage form together with conventional auxiliary materials in the pesticide processing process, can effectively prevent the rhynchophorus ferrugineus larvae from boring the stems from the wounds to take soft tissues, and has better control effect.

The invention has the beneficial effects that:

1. has certain systemic property, and can prevent injury of red palm weevil to plant wound after use.

2. The kasugamycin component in the invention can protect the trunk from being affected by plant germs, prevent wounds from being damaged by germs, and ensure the normal growth of plants.

3. The hydroxyeneadenine and the amino acid components in the invention can play a role in improving the immunity of plants,

4. the components of the invention act together, thus achieving the purpose of complementing different effects, reducing the medication cost and improving the control effect.

Detailed Description

The following examples are given to further illustrate embodiments of the present invention. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention. The experimental procedures, in which specific conditions are not noted in the following examples, are generally carried out under conventional conditions or conditions recommended by the manufacturers.

Preparation of first and second combined medicine

The first embodiment,

Secondly, identifying the effect of the combined medicine on avoiding the invasion of the rhynchophorus ferrugineus to the plant wound:

experimental materials: selecting four different coconut plantations and four different betel nut plantations in Wenchang city of Hainan province respectively, wherein the coconut plantations are marked as follows: a1, a2, A3 and a4, wherein the areca plantation is marked as follows: b1, B2, B3 and B4. Adult coconut trees and areca-nut trees with harvested fruits or trimmed branches and leaves (with plant wounds) are selected as test trees in each plantation, 200 coconuts and 800 areca-nut trees are selected in total.

The experimental method comprises the following steps: in 7 months in 2020, 100 of the test trees in each plantation were selected as drug-applying trees and 100 were selected as control trees, and the wounds of drug-applying trees in groups I (A1 and B1), II (A2 and B2), III (A3 and B3) and IV (A4 and B4) were sprayed with the combined drugs obtained in examples I, II, III and IV, respectively, and the control trees were: 50 control I (without any drug) and 50 control II (with chlorantraniliprole applied to the wounds).

The experimental results are as follows: in 9 months of 2020, coconut plantations 'A1, A2, A3 and A4' and betel nut plantations 'B1, B2, B3 and B4' are comprehensively investigated, wound infection conditions and red brown weevil invasion conditions are observed, indexes such as wound pathogen infection number and red brown weevil wound invasion number are respectively counted, and infection rate and effective rate are calculated, and the results are shown in Table 1.

TABLE 1 combination drug administration
