The diamondback moth, *Plutella xylostella*, can be managed through various control methods. For physical control, adults are attracted to light, so black lights or UV lamps can be placed every 10 acres to trap and kill large numbers of moths. Biological control involves the use of bacterial insecticides like *Bacillus thuringiensis* (Bt), which effectively targets the larvae, causing significant mortality. Chemical control options include diflubenzuron at 25% or 30%, diluted 500–1000 times, as well as diazinon emulsifiable concentrate (EC) at 1500 times dilution, and Titanop EC or similar products at 2000 times. Spraying should begin early in the infestation cycle, focusing on the underside of leaves or new growth. A regular schedule of spraying every 5–7 days for 3–5 applications is recommended to maintain effectiveness.
For *Spodoptera exigua*, also known as the beet armyworm, physical control methods include using frequency vibration lamps or black lights to attract and kill adult moths. Insect traps such as sweet and sour pots can also be effective. For chemical control, a 15% suspension concentrate applied at 2000–3000 times dilution is commonly used. It's crucial to apply these treatments during the larval stage, particularly when the first instar is active. The spray must cover all parts of the plant thoroughly, with special attention to the underside of leaves and the heart of the plant. Since this pest develops resistance quickly, it’s important to rotate between different insecticides. As a nocturnal species, it's best to spray in the evening. During hot and dry periods, increased irrigation can help reduce population growth.
Another approach for *Spodoptera exigua* includes using sex
Pheromone traps or frequency vibration lamps to monitor and reduce adult populations. Chemical sprays like Ruijin Special at 1500–2000 times dilution, or Divided at 1000–1500 times, are effective. A 15% suspension concentrate can also be used at 5000 times dilution. These products should be applied in the evening for maximum impact, ensuring even coverage on all leaf surfaces.
For cabbage caterpillars, biological control methods include Bt and Chlorella strain No. 6, typically used at 500–800 times dilution. Chemical options include 2.5% EC at 2000 times, 5% Ruijin Special at 2500 times, or 20–25% diflubenzuron at 500–1000 times. However, these agents act slowly, killing larvae only during molting stages. Therefore, early application is essential to prevent severe damage. Regular monitoring and timely intervention are key to successful pest management.
Fluorochemicals
The Fluorochemicals compound is a new field in modern organic chemistry. It has a special physical and chemical properties, so it is widely used in the earliest development of applied pesticides and rat poison. During World War II it was developed in some countries appliedas antimicrobial agents, there are more and more new research suggests that fluorochemical will play an increasingly more important role in the field of anticancer drugs. We started later in the field of fluorochemicals, but we have a strong sense of his enormous potential, and we are increasing investment to catch up. We will custom product which has potential market prospects from gram and kilogram-class through process optimization, enlarged to the size of ton. Currently we have developed more fluorochemical compounds in the benzoic acid range, the number of products have been more than 2017.
