In agricultural production, the overuse of pesticides beyond the recommended limits is one of the main reasons for pesticide residues in food. To avoid exceeding residue standards, it's essential that farmers carefully read and follow the instructions on pesticide labels. Over-application occurs when the amount or frequency of pesticide use exceeds what is stated on the label, which not only increases costs but also leads to higher levels of pesticide residues in crops. Additionally, this practice can accelerate the development of resistance in pests, weeds, and diseases.
Excessive pesticide use can result in higher residues due to several factors: differences in application amounts, the number of times pesticides are used, seasonal variations, and the varying safety intervals and residue limits for different crops. For example, the same pesticide may have different acceptable limits depending on the type of crop it’s applied to.
To prevent misuse, farmers should always follow the guidelines provided on the label. Here are some important tips from the Chinese Pesticide Network:
First, choose high-quality pesticide products from reputable and trustworthy retailers. Second, strictly adhere to the target pests or crops specified on the label. For instance, isocarbophos is only approved for use on rice and cotton, and should not be applied to other crops. Third, be cautious with commonly used pesticides—even if they share the same name, their formulations, concentrations, and application methods may differ. Never mix them without proper guidance.
For example, imidacloprid, a common insecticide, comes in different forms like wettable powders and suspensions. Their application methods vary significantly. Some farmers mistakenly apply 600 grams per liter of imidacloprid suspension meant for rice to crops like cucumbers, leading to excessive residue levels and potential health risks. Always consult the label and follow the instructions precisely to ensure safe and effective use.

The main features of the T8 lamp include:
1. High luminous efficiency: T8 lamps use phosphors and electronic ballasts, which can provide high brightness and high luminous efficiency lighting effect, providing sufficient light for plants.
2. Energy saving and environmental protection: Compared with traditional incandescent lamps, T8 lamps have a higher energy efficiency ratio and longer service life, which can save energy and reduce carbon emissions.
3. Good spectrum: T8 lamps can provide spectra of different wavelengths according to the growth needs of plants, such as blue, red and full spectrum, which is conducive to the growth and reproduction of plants.
4. Easy installation: The T8 lamp adopts the common G13 interface, which can be directly installed on the T8 lamp holder without additional modification and installation work.
In the field of plant planting, T8 lamps are widely used in the growth lighting of indoor flowers, vegetables, fruits, lawns and potted plants. It can provide sufficient light intensity and appropriate spectrum, promote plant photosynthesis and growth and development, improve yield and quality.
It should be noted that different plants have different needs for light, so when choosing T8 lamps, it is necessary to choose the appropriate spectrum and light intensity according to the growth stage and type of plants. At the same time, reasonable lamp layout and use time are also key factors to ensure good plant growth.
