Spectrum Fungicide Technical Name
Azoxystrobin 11% + Tebuconazole 18.3% w/w SC
Product Specifications
Mode of Entry: Systemic and translaminar
Mode of Action: Spectrum combines two complementary fungicidal active ingredients. Azoxystrobin belongs to the Strobilurin group and inhibits fungal respiration by interfering with mitochondrial electron transport. Tebuconazole belongs to the Triazole group and inhibits ergosterol synthesis, disrupting fungal cell membrane development. Together, they provide activity at different stages of fungal development.
Time of Application: Apply preventively or at the initial appearance of disease, depending on disease pressure and crop recommendation.
