Aphids prefer warm and humid environments and are very fertile.
Pests and diseases TOP 1 Aphids
There is black mold found on the leaf, usually concentrated on the back of the leaf, which will cause the leaf to shrink or even wither when severe, what should I do?
●Susceptible insect pest species / Begonia, ivy, white crane taro, ornamental coconut, Fluke tree, etc.
●Causes of pests/ Aphids prefer warm and humid environments, and are very fertile, can reproduce more than 20 generations a year, and can even spread to other plants through wind. Aphids are most likely to occur in high temperature and humidity and no ventilation, which can cause coal disease in addition to direct damage to plants.
●Treatment/Adult insects prefer yellow, can use yellow sticky boards or water trays to trap, once it occurs, immediately cut off the part of the worm and burn it, using ladybugs, flower piles and other natural enemies or administering drugs. In terms of environmental improvement, maintaining good ventilation and paying attention to light can prevent and reduce the risk of occurrence.
"Three Steps to Treatment"
Step 1. Aphids reproduce quickly and are easy to spread, and it is best to treat them immediately after discovery. Use aphid control drugs such as edabolide, dilute to a suitable multiple according to the instructions, or make your own insecticide with garlic or lemon peel, and then fill the adjusted insecticide liquid in the spray can.
Step 2. Each medication interval is 7 to 10 days, 2 to 3 times in a row, when applying the drug, the liquid must be sprayed as much as possible on the back of the leaf, as well as the heart of the aphid cluster, and the finer the particles sprayed, the better the effect.
Step 3. After the application of the drug, the insect pest has been solved, before moving indoors, it is advisable to spray the whole plant with clean water, which can reduce the drug residue to avoid human contact, and can also spray other possible insect pests.
Recommended Agents for The Right Place

When the growth capacity of plants is slightly poor or the environment is suitable for disease, pathogenic bacteria will invade by wounds or natural openings, and high humidity spots will overflow with sticky matter, which is the conidia of pathogenic bacteria.
●Treatment/Common diseases, especially in high temperature and humid environments, can be diluted with suitable agents when they occur, and the whole plant can be sprayed during the disease-prone period. In terms of environmental improvement, pay attention to ventilation and light transmission, and strengthen fertilizer management, reduce the amount of nitrogen fertilizer application, can improve the resistance of plants.
●Befenti
Aminoformates, systemic fungicides, are administered by cuttings or splitting once until the whole plant is moistened.
●Atropamine
Broad-acting agents to inhibit the respiration of pathogenic bacteria to achieve bactericidal effect, but also to treat diseases and diseases, the prevention effect is excellent.
