Pest prevention and control in pollution-free fruit production focuses on the principle of "prevention first, integrated management." It involves timely application of agricultural, chemical, and biological methods to keep pest populations below the economic injury level, ensuring the production of safe, high-quality fruits.
1. Emphasize the use of agricultural control measures
(1) Timely orchard cleaning is essential. Many pests overwinter in dead branches, fallen leaves, bark crevices, and weeds. Removing these materials can effectively reduce pest infestations. For example, weeds and leaves can be buried deeply, tree bark can be carefully scraped, and plastic sheets can be laid under trees to collect and remove diseased parts. These materials should then be burned or disposed of properly to prevent reinfestation.
(2) Selecting disease-resistant and high-quality varieties is crucial. Traditional fruit production often focused on yield and quality, but not enough attention was given to resistance. With the rise of green food demands, it's now essential to choose varieties that are naturally resistant to diseases and pests. This reduces the need for chemical interventions and supports sustainable, pollution-free fruit production.
2. Use chemical pesticides wisely
According to national guidelines for green food production, highly toxic, carcinogenic, teratogenic, and mutagenic pesticides are strictly prohibited. Only low-toxicity, low-residue options like lime sulfur, Bordeaux mixture, and thiophanate-methyl are recommended. Careful selection and proper application are important to avoid overuse. Improving spraying techniques, such as using electrostatic spray technology, enhances coverage, increases adhesion, and reduces pesticide usage while maintaining effectiveness.
3. Promote biological control methods
(1) Utilizing natural enemies is an effective strategy. China has a rich diversity of beneficial insects and predators that can help control pests. Planting nectar crops and cover crops in orchards improves their habitat and provides more food sources, encouraging population growth. In some cases, natural enemies can be bred and released artificially, especially when invasive pests appear. Introducing new natural enemies can also be a preventive measure.
(2) Microbial pesticides are gaining popularity due to their safety and effectiveness. Examples include nucleopolyhedrovirus (NPV), granulosis virus (GV), *Bacillus thuringiensis*, *Beauveria bassiana*, and *Metarhizium anisopliae*. These bio-pesticides target specific pests without harming humans, animals, or the environment. When combined with other control methods, they contribute significantly to achieving over 85% high-quality fruit production in orchards.
Fluorine-Containing Phenol
he fluorine-containing phenol series product is toxic and irritating, it should be avoided absorbed into the body through the skin. And not allow to store with strong oxidant, alkali, hydrochloric acid and acid anhydride , Store with flammable liquid or solid,must be away from heat and open flames,it should be stored in a cool dry place. Most of the fluorine-containing phenol products are stable at room temperature and pressure, but avoid contact with the oxide. In the air it is easily oxidized color.
Manufacture and storage of fluorine-containing phenol series should be carried out in a well ventilated place. Wear appropriate protective equipment and prevent dust from spreading. Wash hands and face thoroughly after handling.
Most of the fluorine-containing phenol series of products can be sublimated. It can cause severe skin burns and eye damage.
So save the fluorine-containing phenol series in sealed containers must be stored in a cool, dark place. It must be stored locked. In the event of a fire extinguishing agent is suitable dry powder, alcohol-resistant foam, water spray, carbon dioxide.
