Pomegranates are delicious and very nutritious, and their market price is decent too, so some growers who want to make money plant pomegranate trees, and during the growing period they may need to use pesticides. So, what pesticides are commonly used on pomegranate trees?

If pomegranate trees do not suffer from pests or diseases, there is no need to use pesticides. However, pomegranate trees may suffer from diseases such as sooty mold, dry rot (white rot), brown spot, black pox and anthracnose, as well as pests such as peach fruit borer, slug moth, aphids, stink bugs, scale insects and cotton leafworm, and you can use the corresponding pesticides to control them.

1. Sooty mold

Symptoms: The affected parts are leaves and fruit. In the early stage of leaf infection, an obvious layer of unknown black matter appears on the leaf surface, but this layer of unknown matter can be easily wiped off by hand, and a substance similar to soot sticks to the leaf, preventing the leaf from carrying out photosynthesis. The main spread is due to insects carrying the virus and staying on the leaves, leaving excrement and so on, and trees with poor ventilation and high temperature and humidity have a higher incidence rate. Fruit infection is similar to that of leaves.

Control: When the disease is severe, spray the affected parts with imibenconazole wettable powder and other agents, once every 9-11 days, for about one month.

2. White rot

Symptoms: It mainly damages flowers, pedicels and fruit. Infected pedicels and receptacles develop brown depressions, and severely diseased flowers fall off early. The diseased parts of infected fruit turn grayish-black, soft, gradually lose water and shrink, and later dense small black granules, namely the fungal pycnidia, grow on them.

Control: During the onset period, spray 47% Kasumin wettable powder at 700 times dilution, 50% thiophanate-methyl wettable powder at 700 times dilution, or 25% benomyl·cyclohexylzinc emulsifiable concentrate at 800 times dilution, once every 10-15 days, for 3-4 treatments.

3. Brown spot

Symptoms: It mainly damages leaves and fruit, causing early fruit drop and later leaf drop. After leaves are infected, brown small spots first appear, which expand into nearly round spots with black to dark brown, slightly raised edges and grayish-black spots in the middle; the symptoms on the back of the leaf are the same as on the front. The spots on fruit are nearly round or irregular, black and slightly sunken, also with gray velvety small granules, and after the fruit colors, the outer edge of the spots turns pale yellowish-white.

Control: From mid-March to early April, spray 10% difenoconazole water-dispersible granules at 1500 times dilution 2-3 times. After late May, use the following pesticides: 40% Fuxing (flusilazole) emulsifiable concentrate at 8000 times dilution, or 25% propiconazole emulsifiable concentrate at 5000 times dilution, or 30% difenoconazole·propiconazole emulsifiable concentrate at 5000 times dilution, or 25% myclobutanil emulsifiable concentrate at 2000 times dilution, or 40% folpet wettable powder at 500-600 times dilution, or 50% captan wettable powder at 600-800 times dilution; choose any one, spray once every 7-10 days, for 2-3 consecutive sprays.

4. Pests

For aphids, you can use 33% water-based chlorpyrifos emulsifiable concentrate or 2.5% imidacloprid wettable powder for control. For the peach fruit borer, you can use 50% phoxim emulsifiable concentrate for control. For slug moths and aphids, you can use decis and fenvalerate for control. For scale insects, you can use methidathion and chlorpyrifos for control.
