Copper Sulfate Specialized 98.0% Powder Fast Supply Speed

• Basic information

· Chemical name: Copper sulfate pentahydrate, commonly known as blue vitriol or bile vitriol 

· Chemical Formula: CuSO₄·5H₂O 

· Appearance: Bright blue crystals or particles. 

· Properties: Readily soluble in water, and the aqueous solution is weakly acidic. It is an important source of copper that plants can absorb.

• The core function of fertilizer: supplementing copper elements

• Copper sulfate is mainly used as a copper fertilizer. Copper is one of the essential trace nutrients for plants. Although its demand is small, its role is crucial.

• The main functions of copper in plant growth:

·The core of enzymatic reactions: It participates in the activation of various enzymes and is an important component of many oxidoreductases. 

· Photosynthesis: Participates in the formation of chloroplasts and promotes photosynthesis. 

· Respiration: Participates in the electron transfer during the respiration process of plants. 

· Lignin synthesis: It helps the lignification of cell walls, enhances the mechanical strength of plants, and improves their resistance to lodging and diseases.

• Applicable crops and symptoms of copper deficiency

• Crops sensitive to copper:

· Cereal crops: wheat, barley, oats, rice (especially rice seedling fields). 

· Fruit trees: citrus fruits, apples, pears, peaches, plums, etc. 

· Cash crops: cotton, flax, tobacco, sunflower, sugar beet, etc. 

· Vegetables: Onions, spinach, carrots, etc.

• Typical symptoms of copper deficiency in plants:

• New leaves lose their green color, turn yellow, wilt, and even turn white. The growth at the top of the plant has stagnated and the top has withered. The tillering of Gramineous crops increases, but they do not produce panicles or the panicle parts are underdeveloped (" panicle but not fruiting "). The leaves of fruit trees are deformed, the branches and tips exude gum, and the quality of the fruits has declined.

• Precautions and Potential Risks

· Toxicity: Copper sulfate is toxic to humans and animals (especially aquatic organisms). Safety precautions should be taken during use and storage to avoid accidental ingestion or contact with the eyes. 

· Risk of pesticide damage: Spraying at excessively high concentrations or at high temperatures can easily cause leaf scorching. Crops sensitive to copper (such as peaches, plums, cabbages, lettuces, etc.) should be used with caution or the concentration should be reduced. 

· Soil accumulation: Long-term and excessive use can lead to the accumulation of copper ions in the soil, damaging soil structure, inhibiting microbial activity, and affecting the availability of other elements (such as iron and zinc), causing soil pollution and ecological risks. 

· Metal corrosiveness: Its solution is corrosive to metals. When preparing and using it, it is not advisable to use metal utensils (iron or aluminum products). It is recommended to use plastic, glass or wooden containers. 

· Compatibility: It should not be mixed with alkaline pesticides or fertilizers, otherwise the efficacy will be reduced or precipitation will occur. Mixing with phosphates may also generate insoluble copper phosphate. 

· Environmental protection: Do not pour the remaining liquid medicine into fish ponds or rivers. The packaging materials should be properly disposed of.

• Summary

Copper sulfate is an ancient, highly efficient but cautiously used agricultural chemical. As a copper fertilizer, it can effectively correct copper deficiency in crops, increase yield and quality. As a pesticide, it offers a low-cost and broad-spectrum disease control solution. However, its toxicity and cumulative environmental risks require users to strictly adhere to scientific dosage and usage methods, advocate precision agriculture, and avoid abuse.
