Fungicides are chemical or biological agents used to prevent or eliminate fungal infections in plants, animals, and humans. They play a crucial role in agriculture by protecting crops from diseases caused by fungi, which can significantly reduce yield and quality.
Types of Fungicides:
1. Contact Fungicides â?? These remain on the surface of plants and prevent fungal spores from germinating.
2. Systemic Fungicides â?? Absorbed by the plant, these move through its tissues to combat existing infections.
3. Protective Fungicides â?? Applied before infection occurs to prevent fungal growth.
4. Curative Fungicides â?? Used after infection to stop the spread of fungi.
Common fungicides include sulfur-based compounds, copper-based solutions, and synthetic chemicals like azoxystrobin and carbendazim. Some organic options, such as neem oil and bicarbonates, are also used in sustainable farming.
Fenazol, a triazole fungicide, is a type of triazole fungicide. Its active ingredient is a colorless crystal that is stable in acidic, alkaline, hot and humid environments. It has broad-spectrum fungicidal activity, strong systemic absorption, and can be conducted to the top of plants, providing protection and therapeutic effects on diseases. It can control stem, leaf and spike diseases of cereal crops (mainly including wheat, barley, rye, corn, etc.) as well as soil-borne diseases (75mg/kg seeds) and seed-borne diseases (200-300mg/kg seeds), such as powdery mildew, rust, cloud pattern disease, leaf spot disease, net spot disease, black spike disease, etc. At the same time, it can also prevent and control diseases spread by soil and seeds. It has a special effect on grain powdery mildew, especially on eradicating the spore piles of wheat powdery mildew. After 5 to 10 days of medication, the originally formed disease spots will disappear. Developed by the British company Jetcon in 1980, it is a sterol demethylation inhibitor that can effectively inhibit the biosynthesis of ergosterol, cause the rupture of fungal cell walls, and has a good protective and therapeutic effect on many diseases caused by basidiomycetes and ascomycetes. It also has a certain fumigation effect, but is inactive against oomycetes and bacteria.
Pentazole, a fungicide, is currently the most active triazocyclic fungicide and an inhibitor of sterol demethylation. Colorless crystal, melting point 57.6-60.3â??, vapor pressure 0.37mPa at 20, density 1.30(20â??). Solubility (25) : 73mg/L in water, 730g/L in ethanol, 770g/L in propanol, 610g/L in toluene, 22g/L in hexane, 400g/L in octanol. pKa1.51. It is stable to hydrolysis and below 350â??. It is absorbed through the active tissues of crops such as roots, stems and leaves, and can be quickly conducted upward in the plant body along with the body fluids. The results of indoor activity determination and field efficacy tests show that it is highly effective against white rot of grapes, and also has good control effects on leaf spot disease, black star disease, anthracnose and powdery mildew. Mode of action: Systemic bactericidal, with therapeutic, protective and eradicating effects. Mechanism of action: Inhibits sterol demethylation and plays a role during the germination and invasion of fungal spores. Control targets: Pathogenic bacteria of the genus Melanoderma in the family Albicarbonaceae, as well as other pathogenic sporomycetes, basidiomycetes and deuteromycetes. Especially the above-mentioned pathogenic bacteria on pumpkins, grapes, pins, ornamental plants and vegetables.
It is a broad-spectrum protective fungicide that can prevent various fungal diseases. The efficacy is stable and the residual period is long. It can be used for crops such as wheat, rice, vegetables, fruit trees, peanuts and tea. For example, for wheat scab, spray 11.3g of 75% wettable powder per 100m2 with 6kg of water. For vegetable diseases (early blight, late blight, leaf mold, leaf spot of tomatoes, downy mildew of melons, anthracnose), spray 135 to 150 grams of 75% wettable powder with 60 to 80 kilograms of water. For downy mildew and powdery mildew on fruit trees, spray 75 to 100 grams of 75% wettable powder mixed with 30 to 40 kilograms of water. In addition, it can also be used for peach rot, scab disease, tea anthracnose, tea cake disease, net cake disease, peanut leaf spot disease, rubber canker disease, cabbage downy mildew and black spot disease, grape anthracnose, potato late blight, eggplant gray mold disease, and orange scab disease.
Benzoone is a benzophenone fungicide developed by BASF of Germany. It was first created by Cyanamide Corporation of the United States (now part of BASF) in 1998. It is mainly used to control powdery mildew and eye spot diseases in crops such as grains, cucumbers and grapes. Chemicalbook has attracted much attention due to its unique mechanism of action. It began to be registered in European countries in 2004. In 2013, the global sales of benzodiazone reached 75 million US dollars. At the end of 2015, it obtained the registration of benzodiazone raw materials and preparations in China.
Benzoone inhibits the spore germination of powdery mildew by interfering with the development and formation of attachment cells during spore germination, and can act on the entire life cycle of fungi. Studies have shown that the number of spore germinations of powdery mildew bacteria after treatment with benzophenone is significantly reduced. Secondly, benzoone interferes with the establishment and formation of polar muscle actin tissue, thereby interfering with and inhibiting the formation of the apical cells of the mycelium of the pathogen. This hinders the normal development and growth of the mycelium, inhibits and hinders the invasion of the powdery mildew pathogen, effectively controls the harm of powdery mildew, and has obvious preventive and therapeutic effects.
Highly efficient and broad-spectrum azole fungicides, with preventive, therapeutic and eradication effects, and strong systemic absorption (capable of both upward and downward conduction). It has a special effect on powdery mildew, rust and black smut. Its bactericidal effect is to inhibit the biosynthesis of ergosterol. It is mainly used for the prevention and control of diseases of crops such as wheat, fruit trees, vegetables, melons and flowers. For the prevention and control of wheat rust disease, spray 6 to 9 grams of 25% wettable powder per 100 square meters with 7.5 kilograms of water, which can also treat barley cloud pattern disease. Or, 75g of 25% wettable powder can be mixed with 46.5 to 188kg of wheat seeds, which can simultaneously treat fishy black smut, scattered black smut and total erosion. For the prevention and control of wheat powdery mildew, use 6 to 9 grams of 25% wettable powder per 100 square meters, mixed with 7.5 kilograms of water. Apply the pesticide at the early stage of the disease. For cucumber powdery mildew, apply 3.8 to 7.5g of 25% wettable powder per 100m �² to 7.5kg of water at the initial stage of the disease. For the prevention and control of corn smut, use 320g of 25% wettable powder to coat 100kg of seeds. Triazolidone has a prominent effect on preventing premature aging of hybrid rice. When 20% emulsified oil was applied at 6mL/100m2, the yield increased by 11% - 16% compared with the control, the daily aging rate of green leaves decreased by 26.85% - 33.2%, the seed setting rate increased by 4.94% - 9.07%, and the 1000-grain weight increased by 3.73% - 4.77%. The use of triazolidone on grain crops such as wheat, corn and sorghum should be discontinued 35 days before the harvest of the crops.
This is a highly effective and low-toxicity systemic conductive fungicide for controlling rice and cotton seedling damping-off disease, and it also has excellent plant growth hormone functions. When used for soil irrigation at 600ppm before and after rice sowing or after emergence, it has a remarkable effect on controlling rice seedling damping-off disease, with a control efficiency of over 93%. Chemicalbook applies the agent containing 300-600 PPM of active ingredients to the fields of planted rice seedlings, sugar beets, saplings, etc., which can prevent diseases caused by Fusarium, Filarium, Botrytis and Fusarium. The liquid medicine containing 0.5-1% of the active ingredients can be used as a seed treatment agent for sugar beets.
