During the height of summer, rising temperatures accelerate the reproduction of pests and diseases in Sichuan pepper. Therefore, it is crucial to focus on pest and disease control. Here is an introduction to common summer pests and diseases of Sichuan pepper and their control methods.
Common Summer Pest and Disease Control for Sichuan Pepper
1. Rust Disease Control
-
Ensure good ventilation and light in the pepper orchard.
-
For mild infections, promptly remove and burn the infected leaves.
-
Spray Bordeaux mixture before the onset of the disease to prevent it.
-
For infected plants, spray with 65% Mancozeb wettable powder at 600-800 times dilution or 15% Triadimefon wettable powder at 800 times dilution.
2. Anthracnose Disease Control
Ensure good ventilation and light in the pepper orchard.
-
Perform deep plowing to prevent over-application of nitrogen fertilizer.
-
Drain water promptly after rainfall.
-
Remove and burn diseased plant debris promptly.
-
During peak infection periods, spray with 65% Mancozeb at 600 times dilution.
3. Gummosis Control
Methods:
-
Timely control of pests like longhorn beetles and buprestid beetles.
-
Thoroughly scrape off ulcerative lesions with a sharp knife.
-
Apply a mixture of gum stopper or Solebar original solution to the wound, then cover with a layer of thin mud to ensure absorption by the tree.
4. Root Rot Control
Methods:
-
Due to frequent heavy rains in summer, build a surrounding circle around the pepper tree canopy in advance to prevent flooding of the root system.
-
For large trees, promptly remove diseased roots, disinfect the cut with Solebar original solution, apply root rot dispersant, and cover with new soil.
5. Sooty Mold Control
Methods:
-
Strengthen orchard management, maintain balanced fertilization, moderate pruning, and clean the orchard to improve ventilation and light.
-
At the onset and peak of the disease, spray with 70% Thiophanate-methyl at 600-1000 times dilution, 50% Carbendazim wettable powder at 1000 times dilution, or 50% Carbendazim wettable powder at 600 times dilution.
6. Red Spider Mite Control
Methods:
-
Conduct thorough cleaning of the orchard before and after bud break, spraying the whole tree with lime sulfur at 5 degrees Baumé.
-
After fruit set, based on tree growth and combined with aphid and other pest control, add acaricides like abamectin, pyridaben, and fenpyroximate.
-
If red spider mites are already present, they form a web-like layer on the leaf surface, so add a penetrant to the miticide.
These are the methods for controlling common summer pests and diseases of Sichuan pepper. Summer is the peak season for pest and disease damage, so it is essential to strengthen management and control measures.
