Safe and simple remedies to get rid of aphids from long beans
Aphid or plant louse is the major enemy of long beans. They rest on the tender shoots of long beans and multiply rapidly killing the plant. Gradually, the flowers fall off and beans get dried. Aphids are carried from one plant to another with the help of ants.
There are several harmless remedies to destroy aphids. Using organic pest control methods is safe for both plants and humans. When chemicals are used, the residue will remain on long beans and this can result in health issues when consumed.
Since organic pesticides are made with natural ingredients, they are safe to use. Also it is easier to prepare these remedies using locally available ingredients.
Here are some organic remedies
Dilute 1 litre rice water (Kanjivellam) adding 3 litre water. Sprinkle this solution on long bean plants. After the rice water dried, remove the dried layer from leaves. Then sprinkle neem oil-garlic emulsion. Lantana-soap solution also is useful.
Applying ash on plants in the morning hours can resist plant louse.
Crush 150 grams of bird’s eye chilli and mix in 10 litres. Sprinkle this solution on plants to avoid pests.
Add 20 grams of Verticillium, a friendly fungus, in 1 litre water and sprinkle every 10 days.
Neem-based pesticides are effective to get rid of insects. Dilute 4 millilitre neem-based pesticide in 1 litre water and apply this to kill plant louse.
If there are only very few plants in the farm, try sweeping the bugs and insects from leaves using an old toothbrush or paint brush.
Water can be pumped with force on the bugs through spray jet to remove them from plants.
Presence of weaver ants on plants can avoid aphids.
Neem seed essence is another remedy for aphid menace.
