Pay attention to control of corn "invisible" pests - horses

At present, summer-sown maize is in a critical growth phase. Among the various pests affecting corn, thrips are one of the most significant threats during the seedling stage. In recent years, corn thrips have become increasingly prevalent in our province, with their occurrence rising year by year. These pests are particularly challenging due to their small size—adults and nymphs measure only 1 to 2 mm in length. Their high activity levels and tendency to hide make them difficult to detect, often leading to missed opportunities for timely control. Moreover, the recent prolonged periods of low temperature and low rainfall have created dry conditions that are favorable for thrips infestation. Corn thrips have entered their peak activity period in mid-July, and it is crucial for farmers to remain vigilant and conduct regular field inspections to prevent further damage. First, the symptoms caused by thrips are quite distinct. Both adults and nymphs feed on corn leaves, resulting in irregular silver-gray streaks along the leaf edges, accompanied by small black spots. As the corn plant grows, the damaged leaves may curl or take on a "tail-like" shape, which can lead to leaf desiccation and even severe seedling death if left unchecked. Second, effective control measures should be implemented. 1. During the early seedling stage, it's important to remove insect-infested plants and clear manure from the field. Strengthening fertilization and irrigation practices can help improve plant resilience. At the same time, surrounding weeds should be promptly removed to reduce the breeding grounds for thrips and minimize their impact on the crop. 2. For chemical control, farmers can use 10% imidacloprid wettable powder at a rate of 20 grams per acre or 4.5% beta-cypermethrin emulsifiable concentrate at 30–45 milliliters per acre, mixed with 30 kg of water for spraying. This treatment not only helps in preventing infestations but also effectively controls existing populations. By combining regular monitoring with timely intervention, farmers can significantly reduce the damage caused by corn thrips and ensure healthier crop development.

Mini Locking Plate

The mini locking system can be used for the fixation of ossicles and small bone fragments, osteotomy, arthrodesis, and replantation and reconstruction of ossicles and small bone fragments.

It is composed of micro locking plate 1.5mm/2.0mm/2.4mm/2.7mm series, covering a variety of plate types and a wide range of indications. The plates are all anatomical design, which reduces the need for shaping and helps to reduce the workload of surgeons. Low profile and countersunk screw design can reduce soft tissue injury. Matching orthopedic screws self-tapping design, convenient implantation, screw plum design, reduce screw hexagonal sliding teeth. The composite hole design can not only realize the compression of the fracture end, but also can be used as a locking internal orthopedic fixation frame. Part of the reconstruction structure is convenient for the surgeon to tailor the implant according to the actual situation in the reoperation, and increase the flexibility of the operation. Its indications are mainly phalanx, metacarpal, scaphoid and other carpal bones, ulnar styloid process and capitulum, radial head and styloid process fracture fixation. The 1.5mm orthopedic implants titanium system is mainly used for the middle and proximal phalanx, the 2.0mm orthopedic plates system for the metacarpal bones, the 2.4mm implant locking plate system for the first metacarpal bones and carpal bones, and the 2.7mm mini plate system is mainly used for the distal ulna and radius. According to the clinical research, the micro-locking plate internal fixation in the treatment of multiple comminuted metacarpal fractures can effectively achieve the anatomical reduction and healing required by the clinic. The patients have good postoperative healing, and the functional recovery of the affected limb is good during the postoperative follow-up. It has good clinical effect and can be further promoted and applied.
