Key highlights
At-a-glance reasons growers reach for TRIZOLE (Tricyclazole 75% WP).
Melanin biosynthesis inhibitor
TRIZOLE blocks melanin formation in the fungus, preventing it from forming the appressoria needed to penetrate and infect rice leaf tissue.
Stops fungal penetration
By disrupting penetration peg formation, TRIZOLE halts the blast fungus before it establishes inside the plant, protecting leaves, nodes, and panicles.
Systemic movement
TRIZOLE is absorbed into rice tissue and translocates within the plant, protecting new growth and reaching infection sites that contact sprays alone may miss.
Preventive and curative
TRIZOLE delivers both preventive protection and curative knockdown of active blast infections when applied at early lesion stage with good coverage.
Protects panicles and neck
Well-timed sprays at boot-leaf to panicle stage guard against neck and panicle blast — the most damaging phases for grain yield and quality.
Long residual effect
Systemic activity inside plant tissue maintains protection between scheduled spray intervals during humid, blast-favourable weather windows.
Easy mixing WP
The wettable powder disperses quickly in water for uniform spray coverage on leaves, sheaths, and panicles across the paddy canopy.
Improved grain quality
Cleaner panicles with fewer blast-affected and chaffy grains improve grain weight, fill, and marketability in paddy and rice.
Higher productivity
Timely blast control preserves leaf area and panicles — supporting higher yield potential and improved grain quality per acre for paddy growers.

Dependable blast control at a farmer-friendly 10 gm per pump helps paddy growers protect yield and grain quality, translating spray spend into stronger returns.
What is Tricyclazole 75% WP?
TRIZOLE (Tricyclazole 75% WP) is a systemic paddy blast fungicide by Harishree Crop Science for preventive and curative control of leaf blast, neck blast, node blast, panicle blast, and the rice blast complex caused by Magnaporthe oryzae in paddy and rice. As a melanin biosynthesis inhibitor, it stops fungal penetration into plant tissue. Recommended dose: 10 gm per pump.
About TRIZOLE Fungicide
TRIZOLE Fungicide is a premium systemic paddy blast fungicide from HARISHREE CROP SCIENCE, formulated as Tricyclazole 75% WP. Rice growers face heavy losses from the blast complex — leaf blast, neck blast, node blast, and panicle blast caused by Magnaporthe oryzae — which strips leaf area, breaks necks, and empties panicles when left unchecked. Specialist blast fungicides like TRIZOLE are trusted because they combine a unique mode of action with preventive and curative activity, protecting the paddy crop through its most vulnerable stages.
The wettable powder (WP) formulation disperses evenly in water for uniform foliar coverage on leaves, sheaths, and panicles. TRIZOLE is engineered for crop safety when used at the recommended 10 gm per pump dose, supporting healthier plant growth, better grain quality, and improved productivity across paddy and rice. For agronomists and dealers, TRIZOLE represents a dependable, blast-focused crop protection solution backed by Harishree quality control and batch-to-batch consistency — designed for the real-world blast pressure rice growers manage every season.
Tricyclazole 75%
Tricyclazole 75% is a systemic fungicide of the triazolobenzothiazole group that acts as a melanin biosynthesis inhibitor (MBI). It blocks the production of melanin, which the blast fungus needs to build the hardened appressoria and penetration pegs that force entry into rice leaf tissue. Without melanin, the fungus cannot penetrate the plant surface — stopping infection at its earliest stage. Tricyclazole is absorbed and translocated within the plant, providing both preventive protection and curative activity against the blast pathogen.
Effective against Magnaporthe oryzae
TRIZOLE is highly effective against Magnaporthe oryzae, the fungus responsible for rice blast. Because its melanin biosynthesis inhibition is a distinct mode of action from most other fungicide groups, TRIZOLE is a valuable rotation partner that helps manage resistance while delivering targeted blast control through the crop cycle.
Dependable blast protection
Together, the systemic movement and melanin-inhibiting action of Tricyclazole 75% deliver dependable preventive and curative blast control. Paddy growers spraying TRIZOLE at early lesion stage and again at boot-leaf to panicle stage gain protection of leaves, nodes, and panicles through the most damaging phases of the blast cycle — protecting grain fill and yield in a way that broad multi-disease products are not specifically designed to match.

Diseases controlled
How TRIZOLE protects paddy against the rice blast complex.
Leaf Blast
Symptoms: Spindle-shaped lesions with greyish centres and dark brown borders on leaves. Under high pressure, lesions merge, blighting large leaf areas and giving the field a scorched appearance.
Crop damage: Leaf blast reduces photosynthetic area at the tillering and vegetative stages, weakening plants and setting the stage for more damaging neck and panicle blast later in the season.
Control benefits: TRIZOLE stops the blast fungus penetrating rice leaves through melanin inhibition. Spray at early lesion stage with uniform coverage for dependable preventive and curative leaf blast control.
Neck Blast
Symptoms: Dark brown to black lesions girdling the neck (panicle base) of the rice plant. The neck rots and weakens, often causing the panicle to break or droop.
Crop damage: Neck blast is the most destructive blast phase — it blocks grain filling, causes whiteheads and chaffy grains, and can cause severe yield loss when it strikes at panicle emergence.
Control benefits: TRIZOLE systemic protection of the neck region limits neck blast establishment. Apply at boot-leaf to panicle emergence stage with thorough coverage to protect grain fill.
Node Blast
Symptoms: Blackish lesions on the stem nodes that weaken and may break the culm. Infected nodes turn dark and brittle, disrupting nutrient flow to developing grains.
Crop damage: Node blast weakens the stem and can cause lodging and poor grain fill above the infected node, reducing both yield and grain quality in affected tillers.
Control benefits: TRIZOLE moves systemically to protect nodes from blast infection. Timely sprays during stem elongation and panicle stages help maintain culm strength and grain development.
Panicle Blast
Symptoms: Lesions on panicle branches and grain stalks that cause partial or complete whitening of the panicle and empty, chaffy grains. Affected panicles stand erect and pale.
Crop damage: Panicle blast directly destroys yield by preventing grain filling. Severe infection at flowering and grain-fill leads to large numbers of unfilled grains and major yield loss.
Control benefits: TRIZOLE protects the panicle when applied preventively at heading. Its melanin-inhibiting action limits panicle blast spread, preserving grain fill and quality.
Rice Blast Complex
Symptoms: Combined presence of leaf, node, neck, and panicle blast through the season, with overlapping lesions on leaves, stems, and panicles in humid, blast-prone fields.
Crop damage: The rice blast complex can devastate susceptible varieties under favourable weather, cutting yields sharply when not managed with well-timed, repeated fungicide sprays.
Control benefits: TRIZOLE provides season-long blast management when used in a planned spray schedule — protecting leaves early and panicles at heading for dependable complex control.
Secondary Fungal Diseases
Symptoms: Opportunistic fungal infections that develop on blast-weakened tissue, adding further leaf spotting and grain discolouration in stressed paddy stands.
Crop damage: Secondary fungal diseases compound blast damage, further reducing leaf health, grain quality, and overall crop vigour in heavily infected fields.
Control benefits: By keeping the canopy healthy and blast-free, TRIZOLE helps limit the secondary fungal diseases that often follow blast damage in dense, humid paddy stands.

What growers say
Feedback from farmers using TRIZOLE Fungicide across India.
TRIZOLE controlled leaf blast in my paddy when lesions started spreading after continuous rain. I sprayed again at panicle stage and neck blast was clearly lower than in neighbouring fields. The panicles filled well and grain quality at harvest was much better this season.
Blast pressure is high in my area every kharif. With TRIZOLE in my spray schedule, the crop stayed green and the panicles were clean. The 10 gm per pump dose is easy to follow and the powder mixes well in the tank.
Neck blast used to cause a lot of whiteheads in my rice. A timely TRIZOLE spray at boot-leaf stage protected the panicles and I saw far fewer chaffy grains. The investment paid off with better yield and profitability at harvest.
