Isothiazolinone is a broad-spectrum fungicide commonly used for disease control on crops and horticultural crops. Its mechanism of action mainly includes the following aspects:
Inhibition of fungal growth: Isothiazolinone can interfere with the function of flagellar kinesin in fungal cells, thereby interfering with the mitotic process of fungal cells and inhibiting fungal growth and reproduction.
Blocking spore germination: Isothiazolidone can interfere with the germination process of fungal spores, affecting their ability to absorb water, germinate, and colonize, thereby inhibiting the reproduction and infection of pathogenic fungi.
Antibacterial effect: Isothiazolinone can interfere with esterases in fungal cells, inhibit their synthesis of essential lipids for cell walls and membranes, thereby disrupting the structure and function of fungal cells and leading to fungal death.
Cure effect: Isothiazolinone also has a certain therapeutic effect on infected plant tissues, which can inhibit the continued development of the disease and promote the recovery of the plant itself.
Overall, isothiazolinone fungicides achieve the effect of inhibiting disease occurrence and controlling already infected plant diseases by interfering with the growth, reproduction, and infection processes of fungi, as well as affecting the structure and function of fungal cells. However, please pay attention to using this fungicide according to the product manual and the correct use method of the pesticide, and follow relevant regulations and safe operating practices.
