What is Chlorothalonil 75% WP?
Hatayu (Chlorothalonil 75% WP) is a broad-spectrum multi-site contact fungicide by Harishree Crop Science for preventive control of early blight, late blight, leaf spot, rust, anthracnose, downy mildew, black rot, and alternaria across potato, tomato, chilli, onion, grapes, groundnut, cucumber, and cabbage. Recommended dose: 30 gm per pump.
About Hatayu Fungicide
Hatayu Fungicide is a premium broad-spectrum contact fungicide from HARISHREE CROP SCIENCE, formulated as Chlorothalonil 75% WP. Indian growers face increasing pressure from early blight, late blight, leaf spot, rust, anthracnose, downy mildew, black rot, and alternaria — diseases that strip leaf area, scar produce, and cut yields when left unchecked. Contact fungicides like Hatayu are trusted because they form a durable protective barrier on plant surfaces, stopping spores before they germinate while supporting strong resistance management programs.
The wettable powder (WP) formulation disperses evenly in water for uniform foliar coverage on leaves, stems, and fruits. Hatayu is engineered for crop safety when used at the recommended 30 gm per pump dose, supporting healthier plant growth, improved produce quality, and better productivity across potato, tomato, chilli, onion, grapes, groundnut, cucumber, and cabbage. For agronomists and dealers, Hatayu represents a dependable preventive crop protection solution backed by Harishree quality control and batch-to-batch consistency — a formulation designed for the real-world disease pressure Indian farmers manage every season.
Chlorothalonil 75%
Chlorothalonil 75% is a broad-spectrum contact (non-systemic) fungicide belonging to the chloronitrile group (FRAC Group M5). It works by binding to and inactivating multiple enzyme and protein groups within fungal cells, disrupting several biochemical processes at once. This multi-site action stops spore germination and prevents fungal growth on the treated plant surface, delivering strong preventive protection before infection establishes.
Multi-site mode of action
Because Chlorothalonil acts on multiple sites rather than a single target, it carries a very low risk of resistance development. This makes Hatayu an excellent rotation and tank-mix partner for systemic fungicides, helping growers protect the long-term effectiveness of their disease management programs while keeping the canopy clean.
Dependable contact protection
As a durable contact fungicide, Hatayu builds a protective film that keeps working on the leaf and fruit surface between sprays. Farmers applying Hatayu preventively, before disease appears, gain dependable broad-spectrum cover plus the resistance-management value of multi-site chemistry — a combination that single-site systemic products cannot match across mixed disease pressure in potato, tomato, chilli, onion, grapes, groundnut, cucumber, and cabbage programs.

Diseases controlled
How Hatayu protects crops against key fungal pathogens.
Early Blight
Symptoms: Dark brown concentric-ring spots on lower leaves of potato and tomato that enlarge and merge. Severe infection causes yellowing, defoliation, and dark sunken lesions on tubers and fruits.
Crop damage: Early blight reduces photosynthetic leaf area, weakens plants, and lowers tuber and fruit yield and quality when defoliation spreads through the canopy during warm, humid weather.
Control benefits: Hatayu forms a protective barrier that stops early blight spores germinating. Spray preventively at first risk and repeat on schedule with uniform coverage for best long-lasting protection.
Late Blight
Symptoms: Water-soaked dark green to brown patches on leaves with white fungal growth on the undersides in humid conditions. Lesions spread rapidly, blighting foliage and rotting tubers and fruits.
Crop damage: Late blight is one of the most destructive potato and tomato diseases — it can destroy a crop within days under cool, wet conditions if not controlled with preventive sprays.
Control benefits: Hatayu's durable contact barrier prevents late blight establishment. Apply preventively before infection, especially in cool humid weather, with thorough coverage of leaf undersides.
Leaf Spot
Symptoms: Circular to irregular brown or dark lesions on leaves, often with yellow halos. Lesions may merge, causing large necrotic patches and premature defoliation across groundnut, tomato, and cucumber.
Crop damage: Leaf spot diseases reduce photosynthetic area and weaken plants. Heavy defoliation lowers yield and produce quality when infections run through the canopy during extended wet periods.
Control benefits: Hatayu protects uninfected leaf tissue and limits new lesion development. Preventive sprays at first risk deliver dependable multi-site cover across the full canopy.
Downy Mildew
Symptoms: Pale yellow to brown angular patches on the upper leaf surface with greyish-white fungal growth beneath in humid conditions. Common on grapes, onion, and cucumber during cool, wet spells.
Crop damage: Downy mildew rapidly destroys leaf area and can defoliate vines and vegetable crops, reducing yield and produce quality severely if not controlled preventively.
Control benefits: Hatayu's protective film stops downy mildew spores germinating on the leaf surface. Apply preventively with full coverage, especially on leaf undersides, before disease appears.
Anthracnose
Symptoms: Sunken dark lesions on fruits, pods, and leaves. Pinkish spore masses may appear in humid conditions. Infected chilli and grape produce become unmarketable when lesions expand rapidly.
Crop damage: Anthracnose damages produce appearance and causes pre-harvest drop. The disease cycle accelerates with rain splash and warm weather, spreading quickly through dense canopies.
Control benefits: Hatayu interrupts the anthracnose cycle by preventing spore germination on the protected surface. Time sprays before flowering and at early fruit-set for maximum crop protection.
Black Rot
Symptoms: V-shaped yellow lesions starting at leaf margins of cabbage and other cole crops, with blackened veins. Affected leaves wilt, dry, and drop as the disease progresses.
Crop damage: Black rot reduces marketable head quality and yield in cabbage and cole crops, with severe infections causing widespread defoliation and rejection at market.
Control benefits: Hatayu provides a protective barrier that limits black rot spread on foliage. Apply preventively with uniform coverage and follow a rotation program for dependable control.

What growers say
Feedback from farmers using Hatayu Fungicide across India.
I started Hatayu sprays on my potato before late blight appeared, as the weather turned cool and humid. The field stayed clean while nearby plots were badly hit. The protective cover lasted well between sprays and tuber quality at harvest was clearly better this season.
Hatayu controlled early blight and leaf spot in my tomato during the humid season. The leaves stayed healthier for longer and fruit quality improved noticeably. The 30 gm per pump dose is easy to mix and the powder disperses well in the tank.
Downy mildew pressure was high in my grapes when I switched to Hatayu in my spray rotation. It gave dependable protection and the bunches stayed clean. I like that it is a contact fungicide that fits well with my systemic products for resistance management.
