Description

Composition Containing Seaweed and Zeolite Having Insecticidal Activities}

The present invention relates to a composition for controlling pests comprising algae and zeolite.

In modern agriculture, various pesticides are used to protect crops from pests, pathogens, weeds, and the like. Agrochemicals play an important role in protecting humans from pests and increasing agricultural productivity, and have been developed in various ways in terms of ingredients, formulations, or functions. Currently, pesticides such as insecticides and herbicides are mainly organic chlorine-based, organic phosphoric acid-based, and carbamate-based pesticides.

These chemically synthesized pesticides not only increase the number of spraying of the pesticides continuously, and gradually decrease the effect of pest control due to the emergence of resistant pests due to the increased spraying, but also have a fatal effect on the natural enemies of pests, causing potential insect pests. can In addition, there is a disadvantage in that the toxicity of agricultural products increases due to the increase in the amount of residual pesticides in agricultural products, and the effect of concentration according to the food chain in the ecosystem due to severe toxicity and low degradability.

As part of the development of next-generation pesticides to overcome the limitations of such synthetic pesticides, eco-friendly pesticides are being actively researched. Eco-friendly pesticides use microorganisms, natural enemies, plant-derived extracts, etc., have little toxicity to humans or livestock compared to chemically synthesized pesticides, and are easily decomposed in nature and are very unlikely to cause environmental pollution, so development of related technologies is required.

On the other hand, seaweed is algae living in the sea, and is classified into red algae, brown algae, dinoflagellates, and golden algae, and is used in frozen desserts, chocolate milk, cottage cheese, whipped cream, instant products, yogurt, jelly, pet food and sauces. It is used for various commercial purposes as a gelling agent, thickener, and stabilizer in food. Zeolite is known as a natural mineral material that can be freely exchanged with other cations because it contains exchangeable cations in a crystal structure composed of aluminum oxide and silicic acid oxide. Environmentally friendly pesticides containing zeolite have not been reported.

Accordingly, the present inventors completed the present invention by conducting research to prepare an eco-friendly insecticide containing seaweed and zeolite that exhibits excellent control effects against various pests without being toxic to the human body or plants.

Experimental Example 1. Confirmation of the excellent insecticidal effect of the insecticidal composition

1-1. Aphids, spider mites, caterpillars and greenhouse whiteflies

In order to confirm the optimal insecticidal composition, 20 aphids, spider mites, larvae, and greenhouse whiteflies were inoculated into a chamber having a size of 10.0 cm × 10.0 cm, respectively. After 24 hours, the number of pests was visually confirmed, and the control rate was calculated according to the following formula to evaluate the insecticidal effect according to the composition (Table 2).

Control rate = (Number of dead pests / Total number of pests) × 100

As a result of the experiment, it was confirmed that a synergistic effect on insecticidal activity was shown when both seaweed and zeolite were included, and the insecticidal effect of Example 1 was the most excellent.

Specifically, the control rates for each pest in Comparative Example 1 and Comparative Example 4 containing only seaweed or zeolite were significantly higher than those of Example 1, Comparative Examples 1 to 3, and Comparative Examples 5 and 6 in which seaweed and zeolite were added at a constant ratio. In view of the low level, it was confirmed that the insecticidal power is increased when both seaweed and zeolite are included as active ingredients.

In the case of Example 1, 100%, 100%, 95%, and 100% of aphids, spider mites, larvae, and greenhouse whiteflies, respectively, compared to Comparative Examples 1 to 6, were particularly excellent in control effect, and the seaweed and zeolite of Example 1 It was confirmed that the weight ratio (25:1) exhibits the best insecticidal effect.

1-2. Grasshoppers and Crickets

In order to confirm the optimal insecticidal composition, 5 locust larvae and cricket larvae were prepared by putting 5 each in a chamber with a size of 10.0 cm × 10.0 cm, and spraying Example 1 and Comparative Examples 1 to 6 three times a day at a distance of 10 cm, After 7 days, the activity of each object was visually confirmed and evaluated on a scale of 1 (no activity-dead object) to 9 (no effect) (Table 3).

As a result of the experiment, it was confirmed that the insecticidal effect of Example 1 was the most excellent.

Specifically, in the case of Example 1, it was confirmed that all five locust larvae and cricket larvae died, and thus the insecticidal effect on locust larvae and cricket larvae was excellent.

In Comparative Example 1 and Comparative Example 4, the degree of activity and movement distance of grasshopper larvae or cricket larvae were only slightly reduced, and in Comparative Examples 1 to 3, 5 and 6, the movement of each pest became dull and the movement distance It was confirmed that the insecticidal effect was excellent when seaweed and zeolite were included, in that it was confirmed that the insecticidal effect was low, unlike the reduced enough to be confirmed with the naked eye.

Experimental Example 2. Asymptomatic confirmation of pesticidal composition

In order to conduct a drug resistance test on the cannabis leaves of Example 1, which was confirmed to have the best insecticidal effect in Experimental Example 1, Example 1 was sprayed on the cannabis leaves three times, and 3 days, 7 days, and 14 days after drug treatment. As a result of judging the degree of weakness to the cannabis leaf at the time of elapse according to Table 4, the results shown in Table 5 were confirmed.

score degree of weakness 0 Weakness is not recognized visually One As a very mild weakness, a small medicine class is recognized. 2 Weakness was recognized on a small part of the treated leaves. 3 About 50% of the treated leaves were weakened. 4 Considerable damage, but still intact 5 Severely injured and dying

division Degree of weakness (0 to 5 points) 3 days 7 days 14 days Example 1 0 0 0

As a result of spraying Example 1 on hemp, sunburn (superficial burning, leaf discoloration, leaf texture damage, withering or drying out), wilting (plant drooping symptoms and whole branches/shoots/leaves) necrosis (death of cells or tissues through injury or disease, particularly in local areas of the trunk), chlorophyll (emptying of leaf material lacking chlorophyll and other components of the leaf except for the skeleton), epiphyte Phenomenon such as (curving downward of leaves or other plant parts due to excessive growth on the upper side) and undergrowth (curving up of leaves or other plant parts due to growth on the lower side) are not observed with the naked eye at all. In that it did not, it was confirmed that Example 1 was weak to cannabis and could be used without symptom problems.

Comparative group 1 containing only seaweed had the lowest insecticidal effect, and the composition according to Example 1 showed the highest insecticidal effect, confirming the synergistic effect of seaweed and zeolite in pest control against hemp. It was confirmed that the insecticidal composition according to the composition of Example 1 can be usefully used for the purpose of controlling pest damage, especially of hemp.
