Mancozeb 80% WP
It is A broad spectrum protectant fungicide with contact action (combination of two fungicides Zainab and Manab). It belongs to the Dithiocarbamate. It is a multi-site inhibitor, toxic to fungal cells membranes. It contains zinc and manganese essential trace elements involved in the metabolism of plants. A protective fungicide which reacts with, and inactivates sulfhydryl (SH) groups of aminoacids and enzymes of fungal cells, resulting in disruption of lipid metabolism, respiration and production of ATP.

Kresoxim-methyl 50% WDG
It is an eradicating fungicide with protective and curative action. It belongs to the oximinoacetate. The mode of action of Kresoxim-methyl results in the inhibition of respiration in the mitochondria of target fungi. It interrupts electron flow by acting at the Qo center on cytochrome bc1 in the respiratory chain.
EQUALIZER (Famoxadone+ Cymoxanil 52.5% WG)
It is an eradicating fungicide with protective and curative action. It belongs to the Oxazolidinedione and Cynoacetamide oxime. The mode of action of Famoxadone results in the inhibition of ubiquinol cytochrome C oxidoreductase enzyme in complex III of cellular respiration. The mode of action of Cymoxanil is not well known and it has an effect on protein production and DNA synthesis of mycelium growth and prevents the formation of disease-causing fungus cells.
Iprodione + Carbendazim 52.5% WP
It is a systemic and contact fungicide with protective and curative with a broad-spectrum action. It belongs to the dicarboximide and benzimidazole. The point of impact of Iprodione, Affects inhibits fungal spore germination and mycelial growth and for Carbendazim is inhibits beta-tubulin synthesis and disruption in mitosis division.
Thiophanate Methyl 70% WP
Dodine 65% WP
It is a systemic, preventive, and curative action. It belongs to the guanidine family, which disrupts the cellular respiration of the pathogen by changing the integrity and permeability of the cell membrane. The mode of action of this fungicide is due to the presence of guanidine, which non-specifically disrupts the structure of the membrane. The lipophilic part of Dodine binds to the lipid part and its polar part to the phosphate group of the phospholipid, causing structural disruption, membrane permeability change, nutrient absorption disruption, and respiratory inhibition.
Elite (fosetyl aluminium 80% WDG)
