Yes, when used at the label dose with basic protective gear. Hexaconazole has low acute toxicity to mammals, with a rat oral LD50 of 2,189 mg/kg, and low toxicity to honeybees and birds. It is moderately toxic to fish, so do not spray near ponds or let washings enter water. Wear gloves, full sleeves and a mask, and do not eat or smoke while spraying.

Hexaconazole 5% SC is a systemic triazole fungicide used to control sheath blight in paddy, powdery mildew in grapes and mango, tikka leaf spot in groundnut, and rust and leaf spot in several field and horticultural crops. It acts both preventively and curatively, and moves inside the plant after spraying rather than sitting only on the surface.

Paddy, grapes, mango, groundnut, chilli, cotton, apple and tea, along with most horticultural crops. Katyayani Hexa 5 Plus carries specific label rates for grapes and mango powdery mildew and paddy sheath blight. Other crops follow the general foliar rate of 2 ml per litre of water.

One litre of Katyayani Hexa 5 Plus Hexaconazole 5% SC is ₹379 on this page. A 500 ml pack is ₹219, and 2 L, 5 L and 10 L packs are also available. Larger packs bring the per-litre cost down, and prices differ between sellers.

It controls diseases caused by Ascomycetes, Basidiomycetes and Deuteromycetes fungi. The main registered uses in India are sheath blight in paddy, powdery mildew in grapes and mango, and tikka leaf spot in groundnut. It is applied as a foliar spray at 200 to 450 ml per acre in 200 to 250 litres of water.

SC stands for Suspension Concentrate. The active ingredient is milled into fine particles and held in suspension in water instead of being dissolved in an organic solvent. An SC mixes cleanly with water, produces no dust like a powder does, carries no solvent smell, and is generally gentler on the crop and the operator than an EC.

Sheath blight in paddy, powdery mildew in grapes and mango, tikka leaf spot in groundnut, apple scab, blister blight in tea, and rust and leaf spot in several crops. It does not control downy mildew or bacterial diseases, because those are caused by organisms a triazole fungicide does not act on.

Two to three sprays per crop season at 10 to 15 day intervals is normal practice. Hexaconazole belongs to FRAC Group 3, the DMI fungicides, so do not use it more than twice in succession. Alternate with a fungicide from a different FRAC group to stop resistance building in the field.

Early morning or late evening, when temperatures are lower and the spray stays on the leaf longer. Spray at the first sign of disease, or ahead of it when weather favours infection. Allow four to six hours without rain after spraying. Avoid the midday heat and avoid spraying in strong wind.

Katyayani Hexa 5 Plus starts at ₹219 for 500 ml and ₹379 for 1 litre, with 2 L, 5 L and 10 L packs available. At the label rate of 200 to 450 ml per acre, one spray costs roughly ₹75 to ₹200 per acre depending on the pack size and the crop.

Most fungicides sold in India carry a two-year shelf life from the date of manufacture, printed on the pack alongside the batch number. Store the container closed and upright in a cool, dry place away from sunlight. An SC that has settled can be shaken back into suspension, but one that has caked hard should not be used.

There is no single answer, because it depends on how you measure. By sales value, azoxystrobin, a strobilurin, is generally cited as the largest-selling fungicide active ingredient worldwide. By volume, mancozeb and sulphur are used more widely. Hexaconazole is not the global leader, but it is one of the most widely used triazoles in Indian paddy and horticulture.
