Post-disaster Crop Disease Prevention and Control Technology

Since July, the province has experienced heavy rainfall along the Huaihe River, the northern part of the Huai, the Jianghuai region, and most parts of the Yangtze River. This has led to significant crop damage, with 12.43 million mu affected and over 2 million mu already harvested. In response to the current situation, the following recommendations are provided for pest control measures after the disaster. **I. Rice Pest Control Techniques** Based on historical data, in areas that have received heavy rainfall, rice planthoppers and leaf folders tend to be more prevalent after floods. Additionally, wind and rain can cause physical damage to rice plants, especially seedlings submerged for extended periods, which increases the risk of bacterial blight caused by *Xanthomonas oryzae*. Moreover, flood-damaged rice plants often have weakened stress resistance, making them more vulnerable to pests and diseases. Therefore, it is crucial to focus on the prevention and control of the following pests and diseases in the coming weeks: First, for flooded rice seedlings, immediate spraying is recommended using 60 grams of 20% imidacloprid mixed with 40 kg of water. If there are 100 planthoppers per 10 stalks or 10 new leaf folders per 10 stalks, add 10% Diflubenzuron (Dagongchen) at 20 g or 63.1% Chlorpyrifos at 55 g per acre, or 20.5% Huiyuan at 70 ml, evenly applied to the field. Second, during the rice panicle development stage, a comprehensive approach should be taken to control rice blast, smut, borer, planthopper, and leaf folder. **Pesticide Options:** - 75% Tricyclazole for panicle blast - 20% Triadimefon for smut and other heading diseases - 10% Dagongchen or 20–25% chlorpyrifos for planthoppers - 40% Chlorpyrifos (48%) for leaf folders Farmers are advised to follow local plant protection station information and work with technicians to ensure proper mixing and application of pesticides, focusing on key pests for maximum effectiveness. **II. Cotton Pest Control Technology** Currently, cotton is in the budding stage. Prolonged flooding can lead to severe yield loss or even total failure. Based on this year’s analysis, the main pests affecting cotton include leafhoppers, bollworms in some regions, thrips, and armyworms near river areas. Spodoptera litura may also appear later in August in flooded areas. **Control Measures:** 1. **Cotton Leafhoppers:** For plots with more than 5% infestation, apply 30 g of 20% Buprofezin or 57% Bismuth per acre, mixed with 50 kg of water. Re-treat after 7 days if necessary. 2. **Bollworms:** Although insect-resistant cotton has reduced Helicoverpa armigera populations, some areas still report increased damage. Use 50 ml of 4.5% Emamectin benzoate or 30 ml of 2.5% Diflubenzuron per acre, sprayed with 50 kg of water. After August 15, use 40 ml of 2.5% Diflubenzuron or 40 ml of 48% Chlorpyrifos per acre, sprayed with 60 kg of water. **III. Other Major Pest Control Techniques** Other pests include corn borers, peanut aphids, Spodoptera litura, and Spodoptera exigua. 1. **Corn Borer Control:** Mix 150 g of 90% Chlorpyrifos or 100 g of a mixture of Chlorpyrifos and BT (such as Special Killing or Insecticide) with 10 kg of fine soil and apply to the corn whorl. 2. **Peanut Aphid Control:** Apply 250 ml of 40% Chlorpyrifos EC or 200 ml of 48% Lufenuron per mu, mixed with 120 kg of water. Spray directly at the base of the plants. Alternatively, mix with 30 kg of sand and sprinkle evenly. 3. **Spodoptera litura/Exigua Control:** These pests often increase after floods, especially in replanted crops like mung beans and corn. Use 100 ml of 40% Chlorpyrifos or 80 ml of 48% Lufenuron per acre, sprayed with 50 kg of water. Manual inspection in the morning or evening can help remove eggs and larvae. For Spodoptera exigua, increase pesticide dosage or use bio-pesticides such as Diqi, Meixu, or Citaibao. **IV. Application Techniques** For each acre (667 m²), use 40–50 kg of water. Focus on the affected areas and apply in deeper water layers for pests like rice borers and planthoppers. Spraying should be done after 4 p.m. to improve efficacy and reduce health risks from high-temperature exposure. **V. Pesticide Safety** Farmers must avoid using banned or highly toxic pesticides. Wear long sleeves and pants, and wash hands and face thoroughly after spraying. Always use clean water and avoid eating or drinking without proper hygiene.

Orthopedic Implant

Orthopedic implants are medical devices used to repair or replace damaged bones or joints,you can called them trauma implants.They can help restore bone and joint function, reduce pain and improve quality of life. The following is detailed information about the common types and uses of orthopaedic implants.

1. Bone screw

Bone screws are long, thin, spike-shaped implants used to attach bones. They are commonly used surgically to hold bones together to promote healing. Bone nails can be used to repair fractures, dislocations of joints, and other bone injuries.

2. Bone plate

A plate is an orthopedic surgical implant that is used to repair broken bones, usually in conjunction with screws, to hold bones together during surgery, and can be used to repair fractures and other bone injuries, promoting bone healing and restoring bone function. Bone plate and screw are usually made of stainless steel, pure titanium and titanium alloy, can be selected according to the different needs of customers.

3. Joint Replacement implants

A joint replacement implant is an implant used to replace a damaged joint. They are usually made of metal, plastic or ceramic and can replace hips, knees, shoulders and more. Joint replacement implants can help reduce pain, improve joint movement and improve quality of life.

Application

This product is suitable for compression and protective fixation of limbs, pelvis, spine and maxillofacial bone fractures in combination with matching bone screws.

Contraindications

1. Loose fracture, poor fracture or severe comminuted fracture, affecting the firm fixation of the implant.

2.allergic to metal or drug abuse, mental illness, systemic neurological disease, immune suppression disorders.

3. The patient is unwilling to restrict activities or not follow the doctor's advice.

4. Any disease affecting implant function and wound healing.

In conclusion, orthopedic implants are an important orthopedic products. Before using orthopedic implants, doctors should evaluate the patient's condition and surgical risks, and select the most suitable orthopaedic trauma implants for the patient.
