Method for identifying wettable powder and emulsion pesticide
At present, there are many brands in the pesticide market, and various types of dosage forms are dazzling. For many products, it is difficult for farmers to identify the authenticity. It is difficult to distinguish between wettable powder and emulsion pesticide. Let's take a look at how to identify these two agents.
The wettable powder should be loose powder, no agglomeration, and uniform color. If the powder is agglomerated, the taste of the medicine is changed, or the mixture is squeezed into a group by hand, it indicates that the medicine has failed. It is also possible to take 30 grams of the medicine into the container, add a small amount of water to make a paste, and add 150 grams of water to stir. If the solubility is not good or precipitates quickly, it indicates that the pesticide has deteriorated.
The emulsion should be a homogeneous liquid with no precipitation or suspension. If it is found that the long-term unused bottled emulsion pesticide is turbid, there is sedimentation or suspension flocculation, the bottle can be shaken vigorously. After standing for 1 hour, if the agent does not stratify, it indicates normal, if stratification occurs again, Indicates that the agent has failed. In addition, the medicine bottle can be warmed in warm water for 1 hour. If the sediment dissolves slowly, it indicates that the pesticide has not deteriorated; if the sediment is difficult to dissolve or insolubilize, it means that it has failed. Or take 1 gram of emulsifiable pesticide, add 100 grams of water, stir well and let stand for 1 hour. If there is no emulsifiable oil on the surface of the liquid, there is no sediment at the bottom, and the liquid is milky white, indicating that the agent is good; if there is sediment at the bottom, the water and oil are layered, indicating The medicine has expired.
Plant growth lighting refers to a technology that provides artificial light sources for plant growth. This lighting technology is mainly used in environments such as indoor cultivation, greenhouse cultivation and vertical farms, and is designed to provide the spectrum and light required by plants to promote their growth and development.
Plants convert light energy into chemical energy through photosynthesis, and different stages of plant growth require different wavelengths of light. Therefore, plant growth lighting systems often use a specific spectrum, such as a combination of blue, red, and white light, to maximize the light needs of plants.
LED plant growth lights have become the mainstream choice for indoor farming lighting. They have the advantages of low energy consumption, high efficiency and long life, providing high-quality light while reducing energy consumption and heat generation. In addition, the LED light source can also adjust the light intensity, spectrum combination and light period through the intelligent control greenhouse lighting system to adapt to the growth needs of different plants.
The application of plant growth lighting allows efficient plant cultivation even in environments where adequate sunlight is not naturally available, as the supplemental lighting. It can extend the time of light, improve the form, quality and yield of plants, so as to achieve the early ripening and increase of crops. Ongoing developments and innovations in plant growth lighting technologies will open up more possibilities for indoor agriculture and growing in special climatic conditions, and play an important role in global food security and agricultural sustainability.Plant Growth Lighting, Indoor Farming Lighting, LED Plant Growth Lights, Supplemental Lighting, Greenhouse Lighting
