Pay attention to orange orchard management before and after fruit harvesting
At present, citrus fruits are reaching maturity one after another, and the management of citrus orchards before and after fruit picking is crucial. It's currently the peak season for pests and diseases in autumn. Field monitoring shows significant infestations: 546 starry sky moths per louvers, 835 eggs per louvers, 751 aphids per louvers, with 274 adults per louvers. The population of *Spiryphus persicae* reaches 100%, *S. xylophilus* at 4.6%, *P. rosacea* at 3.1%, larvae at 1.5%, while anthracnose and fruit drop rates stand at 1.2%. Hilly orange orchards and some production areas in our city are under serious threat.
Based on these conditions, the following measures are recommended to ensure healthy citrus production and post-harvest quality:
1. Strengthen pest control before fruit harvesting, focusing on proper picking, pruning, and weeding to reduce sooty mold, protect fruit appearance, and ensure good storage quality. Apply mineral oil (such as Green Ying) at 200-250 times dilution, or use Siben (Xinyijia) or Jinshuiganyuan. For high-yield orchards, foliar fertilizers like Tsui Kang Potassium and amino acid-based sprays should be added, along with boron and molybdenum. Due to severe leaf miner damage in local citrus areas, leaves of autumn shoots tend to curl, so thorough spraying is essential.
2. After fruit harvesting, immediately clean the orchard and water it. Maintain green cover using grasses and lindens. For orchards affected by crickets, locusts, and other pests, apply insecticides at 150-160 times concentration. Orchards with higher management standards may require a 200-fold dilution. In cases of severe drought, water the orchard first, then proceed with cleaning and pest control.
3. Implement strict fruit-picking and storage practices. First, pick fruits carefully to minimize damage. Second, remove damaged fruits and clean the surface thoroughly. Third, perform side-picking and dipping, soaking each fruit in solution for about one minute, then drying before storage or transport. Fruits should be processed within 24 hours of harvest. The solution must be prepared fresh and used within 48 hours. For treatment, mix 5g of Baike, 5ml of braconazole, and 2–3g of 2,4-D in 15 pounds of water to dip 800–1200 pounds of fruit. Alternatively, use 25g of a commercial product combined with 50ml of Bacillus and 8g of 2,4-D in 100kg of water to treat 5000–6000kg of fruit. This method effectively controls major post-harvest diseases such as Penicillium, green mold, anthracnose, pedicel rot, black rot, and sour rot, providing protection for up to 120 days.
