what is Rotenone 40% ?
Rotenone is an organic substance with a molecular formula of C23H22O6. It is found in the roots of leguminous coronas produced in tropical and subtropical Asia, and is also contained in some Chinese herbal medicines such as sweet potato seeds, bitter sandalwood, and Kunming spatholobi root. Almost insoluble in water, soluble in ethanol,ether and many other organic solvents.
Rotenone decomposes when exposed to light and air. Its solution in organic solvents is colorless. When exposed to the air, it is oxidized, turning yellow, orange, and then dark red, and can precipitate dehydrorotenone and rotenone which are toxic to insects.Ketone crystals.
It exists in the roots of leguminous fish vine plants in tropical and subtropical Asia, and is also found in some Chinese herbal medicines such as ground melon seeds, bitter sandalwood seeds, and Kunming chicken blood vine roots. Almost insoluble in water, soluble in ethanol,ether, and many other organic solvents. When exposed to light and air, it decomposes. Its solution in organic solvents is colorless, and when exposed to air, it is oxidized, turning yellow, orange, and then deep red, and can precipitate crystals of dehydrogenated rotenone and rotenone, which are toxic to insects.

Insecticidal mechanism:
1. Rotenone is widely present in the root bark of plants and is a highly specific substance in toxicology. It has strong contact and stomach toxicity effects on insects, especially butterfly larvae, diamondback moths, and aphids. Early studies have shown that the mechanism of action of rotenone mainly affects the respiratory function of insects, mainly by interacting with a component between NADH dehydrogenase and coenzyme Q. Rotenone inhibits the electron transport chain of pest cells, thereby reducing ATP levels in the organism and ultimately preventing the pest from receiving energy supply, leading to delayed movement, paralysis, and slow death.
2. Mitochondria, NADH dehydrogenase, succinic acid, mannitol, and other substances in many biological cells are sensitive to rotenone. The electron transfer from NADPH to NADH in Setaria cervi mitochondria can be highly inhibited by rotenone, and the activity of the fumarate reductase system in the mitochondria of Setaria digitata, a filarial parasite, is sensitive to rotenone. Rotenone and salicylhydroxamic acid can inhibit the EMT of Trypanosoma brucei inner mitochondrial membrane, thereby indirectly affecting the activity of NADH dehydrogenase; Rotenone can also inhibit the activity of NADH to cytochrome C and NADH to coenzyme Q reductase in the respiratory chain of Trypanosoma brucei mitochondria, with an inhibition rate of up to 80-90%.
Prevention and control targets:
1. Aphids, planthoppers, yellow striped fleas, thrips, yellow guars, ape leafworms, cabbage worms, striped armyworm, beet armyworm, diamondback moth, etc.
2. To control cabbage caterpillars and aphids, 80~120ml of 4% rotenone emulsifiable concentrates shall be used per mu, and 30kg of water shall be added for spray.
3. To control diamondback moth, spray 80~160ml of 4% rotenone emulsifiable concentrates with 30kg of water.
4. To control Spodoptera litura, 80~120ml of 4% rotenone emulsifiable concentrates per mu should be mixed with 30kg of water for spray.
5. To prevent and control vegetable flea beetle, 80 to 160 ml of 4% rotenone emulsifiable concentrate should be mixed with 30 kg of water for spray per mu.
Product features:
1. Strong specificity and rapid pest control; It has a strong killing effect on insects, especially aphids, thrips, and flea beetles, and has strong contact and stomach toxicity effects on larvae such as cabbage butterfly and diamondback moth.
2. Long shelf life; The insecticidal duration of rotenone is long, around 10 days.
3. Easy to decompose when exposed to light, with minimal residue; The medicinal liquid on the surface of the leaves is easily decomposed when exposed to light and does not pollute the environment. The application interval is 3 days.
4. For environmental and animal safety. Rotenone is not only harmful to aquatic animal, but also safe to humans and animals and will not pollute the environment.
5.Prevention and control targets:Aphid, yellow striped flea beetle, thrips, yellow melon, ape leaf beetle, cabbage beetle, etc.
Mechanism of action:
The mechanism of rotenone entering the insect body is to inhibit the mitochondrial respiratory chain, leading to respiratory disorders such as difficulty breathing and convulsions, delayed movement, and paralysis leading to death.
Breeding use:
1. Using 4% rotenone emulsifiable concentrate to clear ponds for shrimp farming: fish can be poisoned to death with 0.025mg/L rotenone, while shrimp can survive in a 10mg/L rotenone solution. Rotenone has a large-scale destructive effect on fish and other organisms, so it is suitable for aquaculture of shrimp and other shrimp ponds. Generally, 667 square meters of water surface and 1 meter of water depth can be used, and 1000ml of 4% Rotenone emulsifiable concentrate can achieve the purpose of pond cleaning. Rotenone can also be used as a snail killer and to capture ornamental fish.
2. Capturing ornamental fish: Many types of fish will quickly surface in a solution with a lethal concentration of rotenone (0.025mg/L). At this time, if they are transferred to a methylene salt solution with a concentration of 5-10mg/L in a timely manner, these fish will immediately recover their vitality. By using this characteristic of rotenone, high-quality ornamental fish can be captured. This method is mainly used in certain scientific and academic research.
3. 5-7% Fish Vine Root Powder Cleaning Pond: 6-8 grams of root powder per cubic meter of 667 square meters of water surface depth
