experiment example 1

[0036] Experimental Example 1: Indoor Vegetable Insect Experiment

[0037] Materials: Cabbage caterpillars, small caterpillars, heartworms, cotton bollworms, beet armyworm larvae, Spodoptera litura larvae, thrips, pod borer larvae, tobacco caterpillars, and Spodoptera frugiperda larvae were caught from vegetable fields, 10 of each pest , a total of 100, put into the glass fish tank.

Embodiment 3

[0038] Example 3 A 60% emulsifiable concentrate was prepared, and the medicinal liquid was yellowish-brown, smoky and spicy, pungent, and had a burning and tingling sensation upon skin contact. Spraying: Dilute the 60% emulsifiable concentrate by 1000 times, and use the Gongnong-16 knapsack type manual sprayer to spray the insects in the tank until all the insects are full of the liquid. After spraying, observe about 2mm of the liquid medicine at the bottom of the tank, and most of the worms are crawling in the liquid medicine.

[0039] Experimental observation record: (about 12 hours after spraying)

[0040] 1. There were 81 dead worms, all of which were at the bottom of the tank, and some of the worms had dark brown changes.

[0041] 2. Of the 19 surviving animals, 14 of them are on the edge of the tank, stretching and creeping slightly, and 5 have crawled to the screen cloth covering the opening of the cylinder, and they did not move. Flickering, alive.

[0047] Experimental Example 2: Security Experiment

[0048] Climate conditions: at noon, the temperature is 29 ℃, dry, no wind.

[0049] Vegetable field experiment: spray the above-mentioned remaining medicinal liquid on the spinach, rapeseed, lettuce, cucumber, tomato, and carob plants in the open-air vegetable field. Some crops have a small amount of aphids. , fruit, without any adverse effects, harmless to crops. Eating lettuce leaves 48 hours after spraying, cucumbers and tomatoes have no odor, discomfort, etc., and is also harmless to ladybugs.

[0050] Animal and human skin experiments: The insecticide was applied to the dog's nose, and it was broken, blistered, and painful the next day. When this insecticide is applied to the back of human fingers, there is a strong burning sensation, pain, and strong tingling sensation, followed by small bubbles.

[0051] This indicates that the pesticide is highly corrosive, and personal protection should be taken when using it.
