1. Origin of active ingredient Kasugamycin
Kasugamycin is an antibiotic isolated from Streptomyces kasugaensis (a strain of the Streptomyces lineage) in 1956 in Nara, Japan by Hamao Umezawa. It is also called Kasumin.
2. Mechanism of action of active ingredient Kasugamycin
Kasugamycin inhibits the growth of bacteria by interfering with their ability to make new proteins, ribosomes being the main target, preventing them from growing or replicating, thereby helping to prevent the spread of pathogens. disease causing agent.
3. Uses of active ingredient Kasugamycin
- Kasugamycin is used to prevent blast disease (Pyricularia oryzae) on rice and diseases caused by Pseudomonas, Erwinia, Xanthomonas and Corynebacterium bacteria such as soft rot, root rot, scar ulcers on potatoes, tomatoes, peppers, cabbage, carrots…
- In rice blast prevention, Kasugamycin is 72.6% effective on leaves and 87.4% effective on cotton blast disease. Kasugamycin needs to be sprayed when the disease first appears and external conditions are favorable for disease development.
4. Toxicity level of Kasugamycin
- The active ingredient is quickly absorbed into plant parts, is unstable to sunlight and has little impact on the air environment.
- In the environment, Kasugamycin is degraded by microorganisms in soil, water and mud. Kasugamycin is metabolized into kasugamycinic acid and kasugabiosamine (non-persistent substances), so although it is easily soluble in water and easily washed away, it has almost no negative impact on the environment.
- Hydrolysis plays an important role in the metabolism of Kasugamycin under natural conditions. Meanwhile, the photochemical process has almost no effect on the metabolism of this antibiotic in soil and water. Kasugamycin has no adverse effects on warm-blooded animals, birds, worms, honey bees and aquatic flora and fauna when used at recommended dosages.
- Kasugamycin is easily soluble in water but does not accumulate in it or in the bodies of fish.
5. Application of active ingredient Kasugamycin to plants
- Rice: Leaf blast (leaf blight), cotton collar blast, yellow leaves, bacterial leaf blight, rice grain smearing
- Cabbage, onions, garlic: Bacterial rot
- Cigarettes and pipe tobacco: Root collar sores
- Watermelon, cucumber, tomato: Root collar ulcer
- Lychee, longan, mango, grape: Anthracnose
- Orange: Scar ulcer
- Article, pepper: Anthracnose
