Kitazin 48% EC Fungicide Uses

Kitazin 48% EC — the technical name listed by CIB&RC for iprobenfos (IBP) — is a systemic organophosphorus (phosphorothiolate) fungicide registered for use in India under the Insecticides Act, 1968, formulated as an emulsifiable concentrate (EC) for foliar spraying. It is best known for the control of blast and sheath blight in paddy, and is also registered for fruit rot/die-back in chilli, early blight in tomato and potato, purple blotch in onion, and anthracnose in pomegranate and grape. This page lists its mode of action, key benefits and the recommended dosage as per the Central Insecticides Board & Registration Committee (CIB&RC) official list of approved fungicide uses (Government of India).

Mode of Action

Iprobenfos (sold under the name Kitazin) is an organophosphorus fungicide of the phosphorothiolate type — FRAC Group 6 (phospholipid biosynthesis inhibitors, methyltransferase). It blocks the formation of phosphatidylcholine, a key building block of fungal cell membranes, so the fungal hyphae cannot grow and penetrate the plant tissue. It is systemic: it is absorbed through the leaves (and in paddy also through the leaf sheath) and moves within the plant, giving both protective and curative action against blast and sheath blight.

Features & Benefits

• Systemic action — absorbed by the plant and moved within the tissue, so it protects as well as acts on early infections.
• Long-established fungicide for blast and sheath blight, the two main fungal diseases of paddy.
• Also registered for fruit rot/die-back, early blight, purple blotch and anthracnose in vegetable and fruit crops.
• A different mode of action (FRAC Group 6) from triazole and strobilurin fungicides, useful in rotation for resistance management.
• Emulsifiable concentrate (EC) formulation that mixes easily with water to form a uniform spray.

Recommended Usage of Kitazin 48% EC Fungicide

The table below gives the recommended spray concentration, water volume and waiting period for each crop, as registered by CIB&RC — see the note below the table for details. Always confirm against the current product label before use.

CIB&RC registers Kitazin 48% EC as a spray concentration rather than a per-hectare rate, so no per-acre conversion is made: for every crop listed, the CIB list gives 0.10% a.i. (100 g a.i. in 100 L of water) and a formulation dose of 0.20%, printed as "0.20% or 200 ml in 200 L of water", with the water volume "as required depending upon crop stage and plant protection equipment used". *These are fixed mixing concentrations, not per-acre quantities — the total spray volume depends on crop stage, canopy and sprayer. Because the CIB entry's percentage and ml-per-litre wording do not match exactly, confirm the exact mixing rate on your product's label before use.

How to Use

1. Identify your crop and target disease from the symptom guide above, and note its waiting period from the table.
2. Prepare the spray at the concentration given on your product label (CIB: 0.2% formulation) — add the measured quantity to a half-filled spray tank, stir well and top up with water.
3. Spray enough solution to cover the crop uniformly; the total volume depends on crop stage and the sprayer used.
4. In paddy, spray at the first appearance of blast spots or sheath blight lesions, and direct the spray towards the lower part of the plant for sheath blight.
5. In vegetables and fruit crops, start spraying at the first sign of disease and repeat as advised by your local agricultural extension office.
6. Spray in calm weather in the early morning or late evening, and avoid spraying if rain is expected within a few hours.

Precautions & Safety

• Wear appropriate PPE — mask/respirator, gloves, goggles and full-sleeved clothing — while mixing and spraying, and avoid inhaling the spray mist or getting the liquid on skin.
• Iprobenfos is an organophosphorus compound — if headache, dizziness, nausea, sweating or blurred vision occur during or after spraying, stop work, move to fresh air and get medical help immediately, showing the product label.
• Respect the waiting period (PHI) given in the table before harvesting — 3 days for chilli, 5 days for tomato, 10 days for pomegranate, 15 days for paddy and grape, 48 days for potato and 63 days for onion.
• Keep away from fire and flames — EC formulations contain flammable solvents.
• Do not let spray wash or rinse water reach ponds, fish tanks, streams or drinking-water sources.
• Store in the original, tightly closed container in a cool, dry place away from direct sunlight, food and feed, and out of reach of children and livestock.
• Wash hands, face and any exposed skin thoroughly with soap and water after handling, and change out of contaminated clothing before eating, drinking or smoking.
