Description

Composition for disease controlling of horticultural crops {Composition for disease controlling of horticultural crops}

Disclosed herein is a composition for controlling diseases of horticultural crops.

Among various crops, especially pests occurring in horticultural crops, since they directly or indirectly harm horticultural crops, chemical pesticides have been sprayed in order to harvest more high-quality horticultural crops. However, the pesticide damages the natural wax layer on the plant surface, thereby inhibiting the role of the natural wax layer. In addition, excessive use of pesticides not only pollutes the environment, such as soil, but also causes destruction of the ecosystem and strengthens resistance to pests and diseases of crops.

Japanese Unexamined Patent Publication No. 2019-500015 discloses a seed coating composition for preventing damage to seeds. However, as it relates only to the composition for coating the seed, not the crop itself, the disease control of the crop after the seed germinates is not predicted. On the other hand, in the composition for controlling diseases of horticultural crops containing wax as a main component, when stored at room temperature or diluted in water, it tends to harden into a solid state, making it difficult to store and use. Accordingly, there is a need for research and development of a composition for controlling diseases of horticultural crops that protects the wax layer of horticultural crops and has excellent stability.

Japanese Laid-open Patent No. 2019-500015

At least one, and the content ratio of the paraffin wax and the nonionic surfactant is 4 to 20: 1 based on weight, providing a composition for controlling diseases of horticultural crops.

According to the present disclosure, there is an advantage in that it is possible to provide a composition for controlling diseases of horticultural crops having excellent stability while protecting the wax layer of horticultural crops.

All plants, including horticultural crops, have their leaves and pericarp coated with a natural wax layer. Paraffin wax is a main component of the natural wax layer, and when the composition of the present disclosure containing paraffin wax is applied to the surface of a plant, it is possible to restore the plant's natural wax protective film. In this way, the natural wax protective film is protected, (1) the effect of reducing excessive moisture absorption and reducing heat loss, (2) the effect of reducing scorching due to strong sunlight, (3) coating the plant to prevent the invasion and germination of pathogens (4) the effect of suffocating microscopic insects by blocking the airway of microscopic insects, (5) the effect of preventing the spread of germs by water, rain, wind, etc., (6) when transplanting plants (7) Efficacy to increase survival power, (7) Efficacy to maintain the effect of pesticides when used together with pesticides and reduce loss due to rain, and (8) Reduce damage caused by abnormal weather (frozen sea, cold sea, drought, high temperature, etc.) Efficacy, etc. can be exerted.

<Test Example 1> Evaluation of stability of composition

1. Evaluation method

Regarding the composition of Preparation Example 1, the degree of separation of the formulation was visually observed at room temperature to evaluate the formulation formation stability. The results are shown in Table 2 (○: dispersed, △: precipitated, X: separated, △X: both precipitated and separated).

2. Evaluation results

From Table 2, examples 1 and 2, which do not contain paraffin oil and have a content ratio of paraffin wax and nonionic surfactant in a preferred range, show excellent results in terms of stability.

<Test Example 2> Evaluation of the control efficacy of the composition 1

1. Evaluation method

Three leaf stage cucumbers were grown in plastic pots with a diameter of 6 cm in a greenhouse. The composition of Preparation Example 1 was diluted by adding 500 times the weight of water, and then the diluted formulation was sprayed on cucumbers using a sprayer. The next day, a suspension of cucumber powdery mildew spores was spray-inoculated. It was left in the greenhouse for 10 days, and the diseased area ratio of the first leaf and the second leaf (the first leaf and the second leaf from the bottom) was visually inspected to determine the control value. Control value (%) was calculated using the following formula.

[Equation 1]

The results are shown in Table 3.

2. Evaluation results

From Table 3, examples 1 and 2, which do not contain paraffin oil and have a content ratio of paraffin wax and nonionic surfactant in the preferred range, show excellent results in terms of control efficacy.

<Test Example 3> Evaluation of the control efficacy of the composition 2

1. Evaluation method

Pears (Shingo pears) were bred at the pear test site (Godong-ri, Geumcheon-myeon, Naju-si, Jeollanam-do). Pear black spot and pear red spot spore suspensions were spray inoculated. Example 2 Sample 1 in which the composition was diluted 500 times with water, Sample 2 in which a conventional drug (difenoconazole) was added in an amount of 1/2 of the amount used on the market to the sample 1, and only the conventional drug (difenoconazole) Sample 3 consisting of the amount used on the market was sprayed on the pear using a sprayer (spraying repeatedly 3 times). Disease morbidity and control value were obtained on the 5th day after the final drug treatment. Disease rate (%) and control value (%) were calculated using the following formula.

[Equation 2]

2. Evaluation results

From Tables 4 and 5, it can be seen that the control value is 65.3% even when only Sample 1 in which the composition of Example 2 is diluted with 500 times water is used, indicating relatively excellent control efficacy. In the case of sample 2, it can be seen that despite the addition of a conventional drug (difenoconazole) in a content of 1/2 compared to the amount used on the market, 90.1% control value is exhibited, indicating a very significant control efficacy.

<Test Example 4> Confirmation of properties of the composition

1. Evaluation method

With respect to the composition of Example 2 of Preparation Example 1, the properties of the composition were visually observed and confirmed. For comparison, a paraffin wax raw material component and a carnauba wax raw material component were prepared. In addition, for comparison, paraffin wax components were melted and stored at room temperature. The results are shown in Figures 1 to 3. Figure 1a shows the properties of the paraffin wax raw material component. Figure 1b shows the properties of carnauba wax raw material components. Figure 2 shows the properties of the paraffin wax component stored at room temperature after melting. 3a and 3b show properties of a composition according to an embodiment of the present disclosure.

2. Evaluation results

1 to 3, the paraffin wax raw material component, the carnauba wax raw material component, and the paraffin wax component stored after being melted are solid at room temperature, while Example 2 composition containing paraffin wax, carnauba wax and a nonionic surfactant In the case of, it can be seen that the composition does not tend to solidify at room temperature and is easy to store and use.

Although the present invention has been described with respect to the preferred embodiments mentioned above, various modifications and variations are possible without departing from the spirit and scope of the invention. Accordingly, the scope of the appended claims is intended to include such modifications and variations insofar as they fall within the scope of the present invention.
