Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a fungicidal agent applied to fruit pods.

Traditionally, fruit plants have been treated with fungicides to protect them from pathogenic bacteria.

However, commonly used disinfectants, such as organochlorine disinfectants typified by Daconil, organocopper disinfectants such as Oxine Copper, antibiotics typified by Poliococcin, captafor, and cabtan, are harmful to diseases. It protects fruit from bacteria, or high concentrations can cause chemical damage.

In addition, even if it does not cause chemical damage, the surface of the fruit becomes rough.

Alternatively, there were drawbacks such as low effectiveness in protecting the fruit against disease-causing bacteria.

Therefore, the purpose of the present invention is not only to protect the fruit from pathogenic bacteria using a fungicide, but also to protect the fruit surface from chemical damage, improve its luster, and increase its commercial value.

More specifically, the present invention is characterized in that the fruit pods are treated with a fungicidal agent containing orthomethoxycinnamaldehyde as a main component produced from plants.

Therefore, it is effective in protecting fruits from pathogenic bacteria even at low concentrations, and even when treated at high concentrations, it does not cause any effects such as phytotoxicity on fruits because it is produced from the plant body. In fact, it does not cause any problems when used in combination with insecticides such as organophosphorus insecticides, which are currently commonly used for the purpose of protecting against pests, and it does not cause any problems when mixed with other fungicides. Even when used, it is possible to fully demonstrate the intended effect.

Therefore, the present invention proposes that the fungicidal agent orthomethoxycinnamaldehyde can be used not only as a fungicide-proof bag by treating the fruit casing alone, but also as a fungicide-proof and insect-proof bag by mixing it with an insecticide. is possible.

Next, the effect of using the fruit mount of the present invention will be explained in detail through a comparative experiment on a conventional machine.

OOPPM (3) Treatment method A predetermined concentration of the above-mentioned chemical agent is dispersed or dissolved in water and applied to base paper.

Next, it is completely dried and processed with paraffin.
Make a bag and insert the sample.

(4) Bag size Large bag: 135 mm x 160 mm Small bag: 78 mm x 107 mm A paraffin bag that had not been treated with bacteria was used.

e) Fertilization management and pesticide application are based on conventional methods.

f) Survey results g) Discussion 1 This year was a year in which damage caused by black spot disease was higher than in previous years.

However, there are considerable differences among conventional products in terms of their susceptibility to disease, and it is clear whether they are effective against pathogenic bacteria or not.

The protective effect of the fruit pods of the present invention against black spot fungi is 500%
PPM is better than conventional products, 11000PP and 20
The effect at 00 PPM was significantly better than the others.

2. Are there significant differences in the results of skin rising depending on the specimen, and does this serve as a criterion for quality based on the skin? It is due to the size of the sunspot cork and the cork between sunspots, and the sunspot cork plays a role in the respiration of the fruit. Considering that the stomata have died, it is thought that the cause of this is that the bag was filled with a small amount of fungicide that was applied to the fruit pods, impairing their respiration.

In particular, if the lower standard value of cork appears in more than 1/3 of the total product, the commercial value is significantly inferior and the impact on profits is significant.

3. The rust phenomenon that occurs on 20th century pears is caused by physical damage caused by the fruit or branches and leaves, but the majority of rust is caused by the adhesion of pathogenic bacteria, and it is similar to the effect on black spot fungi mentioned above. This seems to indicate the degree of incidence of antibacterial effects of the fungicides applied to fruit mounts.

Therefore, the fruit mount of the present invention is more effective than others in preventing rusty fruit.

Examples ■Field test on apples a)Test location: Kanase-cho, Higashikanbara-gun, Niigata Prefecture, Muka-Kase Apple Association) Enter the variety and combination results in the table.

7″S) Specimen The same specimen as used in Experimental Example 1 was used.

2) The timing is right Obukuro June 25, 1978 e) Fertilization management and pesticide spraying are based on conventional methods.

f) Survey results g) Consideration 1 The prevalence of spot disease, sous-huff disease, and susten's disease varies depending on each specimen at a certain ratio, and these pathogenic bacteria can be reduced on average by treatment with highly effective fungicides. I want to be protected.

According to the numerical values shown in Tables 2 and 3, there was a clear difference between the conventional product and the fruit mount according to the present invention.

Particularly, 1. of the present invention. OOOPPMb2. In OOOPPM, almost perfect effect was demonstrated.

2. There are considerable differences in the quality of the skin texture and the magnitude of the rust phenomenon depending on the type of fungicide, and as seen in the fruit packaging according to the present invention, the differences are also significant depending on the concentration.

Particular attention must be paid to the occurrence of rusty fruit, as this affects the commercial value of the fruit.

EXPERIMENTAL EXAMPLE ■ Test for effectiveness in inhibiting the growth of pathogenic bacteria July 23, 1971 The Japanese test differs from Experimental Examples 1 and 2 above in that it examines whether the specimen is directly effective against pathogenic bacteria.

2 Place the above sample paper on top of it and bring it into close contact with the culture medium.

3. Drop each of the above three types of paper-supplying bacteria onto it to inoculate it.

4 Place it in a thermostatic chamber and culture it, and observe the growth state of the test bacteria after 3, 5, and 7 days.

No. 0 Investigation results D) Discussion Is this test different from those in Experimental Examples 1 and 2 above, in which fruit bags are directly covered with fruit to investigate the effect, or is it a fungicide that is applied to fruit bags? , is effective for investigating how effective it is against pathogenic bacteria.

In this test, it was clearly demonstrated that the orthomethoxycinnamaldehyde treated in the fruit bags of the present invention was highly effective against various pathogenic bacteria.

The above experimental examples show the quality of the protective effect caused by the type of fungicide applied to the fruit bag and the magnitude of the effect that the fruit bag has on the fruit. As mentioned earlier, the fruit bags that have been used conventionally cannot satisfy all of these conditions, as mentioned above, which is the essential condition for making the fruit look beautiful and strong at the same time. Not yet reached.

For example, captafol, which is thought to be the most effective at protecting fruits from pathogens, was extremely less effective than skin in preventing rough fruit surfaces, and had the worst results compared to other fungicides.

However, as is clear from various experimental examples, the fruit growing bag of the present invention satisfies all of the above conditions, being effective in protecting fruits from pathogenic bacteria, and with little occurrence of cork or rust, which is thought to be affected by fungicides. This is an excellent fruit bag made by Sukoshichi.

For example, the effect of protecting fruits from pathogenic bacteria is the most effective among the conventionally used methods, as shown in Table 1, Table 2, and Table 3 for spot rot, sous-haf disease, and susten disease. 2. It has better effects than capufoli. OO
OPPM is perfect.

However, it was found that the effect of smoothing the skin, which is thought to indicate roughness of the fruit surface, is several times more effective than conventional methods.

In addition, Asperg i l, which is the weak point of captafor drug,
The present invention also applies to 1. OOO
It has become clear that perfect effects can be expected from PPM.

When examining the effective upper limit and lower limit content of orthomethoxycinnamaldehyde based on Tables 1 to 6, the present invention agent 5

Therefore, it can be concluded that a base paper weight ratio of 500 PPM does not have an extremely significant antibacterial effect.

However, if the base paper weight ratio is 11,000PP or more, Table 4
- It has remarkable antibacterial activity as shown in Figure 6.

Therefore, it is concluded that the lower limit for containing orthomethoxycinnamaldehyde in fruit bags is 1,000 PPM based on the weight of the base paper.

As for the upper limit, if the content is at its maximum, it is expected that the antibacterial activity will be poor, but considering it from the viewpoint of drug damage, based on the tests in Tables 4 to 6, the base paper weight ratio is 10. OOO
It is concluded that PPM is appropriate.
