In rural areas, aphids are a common pest that attaches to the leaves and stems of plants and feeds on plant sap, causing plants to grow slowly, turn yellow or wilt leaves, and in severe cases, even cause plant death. In order to control aphids, in addition to the use of pesticides, there are some soil methods that can be tried.
First, use plant ash for prevention and control.
Grass ash is a natural insecticide, it contains a lot of potassium, calcium, magnesium and other trace elements, but also contains some plant growth hormones and insecticidal components. Dissolving plant ash in water, filtering out the residue and spraying it on plants with aphids can effectively kill aphids.
Second, use vinegar for prevention and control.
Vinegar contains acetic acid, which has a certain stimulating effect on aphids and is able to kill them. Mixing vinegar and water in a ratio of 1:1 and spraying it on plants with aphids, once a day, for several days, can effectively control the damage of aphids.
Third, use pepper for prevention and control.
Sichuan pepper is a common condiment, it contains a substance called Sichuan pepper, which has a good repellent and killing effect on aphids. Soak the peppercorns in warm water for about 30 minutes, then filter out the residue and spray the pepper water on the plants with aphids, which can effectively kill the aphids.
Fourth, use ginger for prevention and control.
Ginger is a common ingredient that contains a substance called gingerol, which has a certain killing effect on aphids. After slicing the ginger, soak it in warm water for about 30 minutes, then filter out the residue and spray the ginger water on the plants with aphids to effectively kill the aphids.
These soil methods can be used to control aphids, but it should be noted that these methods are not a panacea, and if the plant is seriously damaged, it also needs to be combined with pesticides for control. At the same time, when using these soil methods, it is also necessary to pay attention to safety issues and do not let these substances come into contact with ** and eyes.
