Due to high temperature, high humidity and many types of diseases, once the prevention and control is ineffective, it is easy to cause an outbreak, resulting in huge yield losses. In severe cases, it can cause a total crop failure, which is very harmful. Today, I recommend an excellent fungicide formula, which has a good control effect on gray mold, powdery mildew, leaf mold, brown spot, brown rot, root rot, etc. in the greenhouse, especially gray mold and powdery mildew.
1. Introduction to the agent
This agent is pyraclostrobin·boscalid suspension, which is a compound of pyraclostrobin and boscalid. It has strong permeability and good systemic absorption, and has the effects of protection, prevention, treatment and eradication of diseases.
Pyraclostrobin is a methoxyacrylate fungicide, which is widely used in the prevention and control of diseases of various crops. It has the characteristics of broad fungicide spectrum, fast action speed, long lasting effect, and thorough fungicide. It also has the functions of improving crop physiological functions, enhancing crop stress resistance, and improving crop quality.
Boscalid is a new type of nicotinamide fungicide, which also has the advantages of broad fungicide spectrum, long lasting effect, and good systemicity. The combination of the two has obvious synergistic effect, and is effective in preventing and controlling diseases such as powdery mildew, gray mold, brown rot, rot, and root rot.
2. Main features
(1) Broad fungicide spectrum: Pyraclostrobin·Boscalid can be used to prevent and control gray mold, white rot, leaf mold, rot, root rot, brown rot, and other diseases, and has a good control effect.
(2) Good rapid effect: The agent has strong permeability and can quickly penetrate into the leaves and stems, quickly kill pathogens in various parts, and control the harm of pathogens on the same day after application.
(3) Long lasting effect: The agent has the characteristic of conducting to the top, and can be conducted to the tip and edge of the plant through the wood, effectively reducing the speed of drug dissolution and achieving the effect of continuous killing of pathogens. The lasting effect can reach more than 15 days.
(4) No cross-resistance: Diseases such as gray mold and rot are most likely to develop drug resistance. The agent has no cross-resistance with agents such as pyrimethanil and isoprodinil, and has higher activity. According to experiments, the control effect of the agent on gray mold is more than 10 times higher than that of pyrimethanil.
(5) More thorough treatment: Pyraclostrobin·Boscalid has strong permeability and good systemic absorption. It has the effects of preventing, protecting, treating and eradicating diseases such as gray mold and powdery mildew, and has a good killing effect on pathogens inside and outside the plant.
(6) Good safety: Pyraclostrobin·Boscalid is safe for crops and can be used at any time of the crop. There has been no phytotoxicity, making it safer and more reliable to use.
3. Applicable crops
Pyraclostrobin·Boscalid is safe and can be widely used in vegetables such as tomatoes, peppers, strawberries, cucumbers, and eggplants.
4. Usage technology
Before or at the early stage of gray mold in strawberries, cucumbers, tomatoes, etc., 38% pyraclostrobin·Boscalid suspension can be used at 30-50 ml/mu, diluted with water and sprayed once every 7 days for 2 to 3 times in a row. This can basically eradicate stubborn diseases such as gray mold and powdery mildew.
