1、 Treatment method

1. Washing powder water: use the common washing powder at home, add 300 times of water, stir it evenly with chopsticks, or shake it until the washing powder dissolves and spray insects. You can also use the dishwasher detergent, and the insecticidal effect is also good

2. Ash water: collect the remaining cigarette butts, about 50-100, and then put them in a container, plus 200-300ml of clean water. Soak it for one day and one night, mash it, and then filter out the residue. Finally, use this water to spray the place where there are insects. You can also add about 0.2g baking soda or edible alkali, and the effect will be better

2、 Treatment according to insects

1. Aphid: when Pueraria lobata is invaded by it, its leaves will curl, even wither and die. If there are aphids on the plant, it is recommended to use imidacloprid and Pirimicarb. However, these drugs are toxic and must be careful when using them

2. Scale insects: once endangered by this kind of insect, it is necessary to immediately spray the insect with Omethoate or malathion. If you insist on using it 2-3 times, you will have a good effect. Use the drug every 7-10 days
