High-efficiency application in greenhouses
In a greenhouse, the traditional method of applying pesticides through spraying not only increases humidity inside the structure, which can promote the occurrence and damage caused by pests and diseases, but also accelerates their spread, leading to rapid infestations and significant economic losses. To improve effectiveness and convenience, several alternative methods have been developed.
One such method is the **soil incorporation technique**, where insecticides and fungicides are mixed into seed coatings, granules, or tablets that are applied directly to the soil. As the plant absorbs these substances through its root system, they are transported throughout the plant, offering systemic protection against pests. This method reduces environmental pollution and minimizes the risk of phytotoxicity to sensitive crops. It is particularly effective for controlling aphids, mites, and underground pests in greenhouses.
Another approach is the **dust application method**, in which the pesticide is processed into a fine powder and dispersed into the air using a specialized device. The resulting dust settles evenly on all parts of the plants and in every corner of the greenhouse, ensuring thorough coverage. This method improves the distribution of the active ingredients, enhances absorption, and increases the efficiency of the treatment, resulting in better pest and disease control.
The **smoke application method** involves burning a special aerosol formulation inside the greenhouse, allowing the smoke to spread throughout the space and effectively target pests and pathogens. Commonly used formulations include chlorothalonil and dichlorvos, which are effective against downy mildew, powdery mildew, late blight, gray mold, and cockroaches. This method requires no additional equipment, saves labor, is cost-effective, and ensures even coverage. The smoke can reach every hidden area, making it highly efficient. According to **Chinese Pesticide Network**, this method can achieve a control rate of over 95%, delivering consistent and reliable results.
These advanced application techniques not only enhance the effectiveness of pest and disease management but also reduce the negative impact on the environment and human health. Choosing the right method based on the specific conditions of the greenhouse can lead to more sustainable and efficient agricultural practices.
