What are the applications of Captan?
(1) Seed treatment: potato, sweet potato, cotton, corn, wheat, rice, etc.
Captan has a greater opportunity in the direction of seed treatment. It is effective against root rot, sheath blight, smut, stem rot, blight, bakanae, black mole, scab, and blight of various crops. diseases, etc. have a good preventive effect. At the same time, it has the characteristics of being safe, promoting tissue wound healing, preventing seed rot, and stimulating root growth. However, it should be noted that captan is a protective fungicide, which is less effective against germs inside the seeds, and it will have a better effect when registered or used together with systemic fungicides.
(2) Soil and root treatment: ginseng, panax notoginseng, American ginseng, chrysanthemum, strawberry, ginger, celery, pepper, etc.
Captan has the greatest market opportunities in soil treatment and root diseases. Captan has good control effects on damping-off, blight, stem rot, blight, root rot and other diseases of various crops. Captan has high safety to crops and has obvious promoting effect on the root system of crops.
At the same time, captan can be adapted to a variety of application scenarios, such as root irrigation, drip irrigation (suspending agent is recommended), soil/fertilizer spreading, flushing with water (not recommended for flood irrigation), before transplanting Diversified use methods such as root dipping enable Captan to meet the needs of disease control in different crops, different growth stages, and different cultivation environments. What needs to be reminded is that Captan is a broad-spectrum protective fungicide. Its advantages lie in broad-spectrum and disease prevention (that is, to treat "unforeseen" diseases). It is recommended to be used in combination with systemic therapeutic fungicides when diseases occur.
(3) Foliar spray: pears, citrus, apples, peach trees, lychees, mangoes, grapes, vegetables and medicinal materials, etc.
In the direction of foliar spraying, captan has the advantages of comprehensive disease management and high added value. The reason why the advantage of captan lies in the comprehensive management of diseases is because of its broad-spectrum bactericidal characteristics. Taking grapes as an example, it can prevent downy mildew, gray mold, anthracnose and white rot at the same time, and can prevent sand skin disease and scab on citrus at the same time, and even has a certain effect on citrus spider mites. On potatoes and tomatoes, both early and late blight can be prevented. The overall performance of broad-spectrum and multi-effects is better than that of systemic therapeutic fungicides with stronger specificity.
In particular, captan has excellent effects in killing the hyphae of pathogens and inhibiting the germination of spores of bacteria, so it has a good effect on removing mold layers of diseases such as downy mildew and gray mold, so it has been jokingly called "drying medicine". , "Purple Potion". Combined with Captan’s non-resistance, synergistic effect with most pesticides, and safe use, Captan can be used in combination with systemic therapeutic fungicides in each growth period of crops and used multiple times, so as to prevent Multiple diseases, multiple disease prevention, and comprehensive disease control, so captan is also known as "the magic weapon of bactericidal compound".
