Amistar - Azoxystrobin 23% SC - Syngenta

Why Choose This Product? Key Benefits

• 🍇Disease control across seven labelled crops: Amistar has crop-specific recommendations in fruits, vegetables and cumin. The disease and waiting period change with the crop, allowing the product to be selected for a defined problem rather than a generic claim to treat all crop diseases.
  
• 🍃Systemic fungicidal action: Azoxystrobin acts within the plant system, not only as a surface deposit. Thorough canopy coverage is still important so that systemic activity is supported by correct application rather than used as a reason to leave parts of the crop unsprayed.
  
• 🧬Targets disease-organism respiration: Its FRAC Group 11 mode of action interrupts mitochondrial energy production. Explaining this target also helps growers distinguish Amistar from fungicides in other resistance-management groups.
  
• 🎯Several disease types in the labelled spectrum: The crop table covers relevant mildew, blight, anthracnose and fruit-rot problems. Where two diseases are listed for one crop, the recommendation can address that specified disease spectrum without adding unlisted crops or disease names.
  

Technical Specifications

How It Works: Mode of Action

Amistar contains azoxystrobin, a systemic QoI fungicide in FRAC Group 11. It acts on the respiration process used by susceptible disease-causing organisms to generate energy.

1. Apply to the crop canopy: Prepare the spray for the relevant crop and cover the canopy thoroughly with appropriate plant-protection equipment. Systemic movement complements coverage; it does not remove the need to reach the intended foliage.
   
2. Block an energy-production step: Azoxystrobin inhibits electron transfer at the quinone-outside site of mitochondrial complex III. In plain language, it interferes with a key step in the organism’s respiratory energy supply.
   
3. Limit susceptible disease development: With that energy pathway disrupted, susceptible disease organisms cannot continue normal growth. Use this effect within a crop-specific disease-management plan rather than treating Amistar as a cure for every symptom or as a replacement for diagnosis.
   

FRAC classifies Group 11 QoI fungicides as a high resistance-risk group, with cross-resistance among members. Follow local crop-specific resistance-management advice and rotate or combine only as permitted by the relevant product labels; changing to another Group 11 brand alone is not a change of mode of action. No unverified tank mixture or repeat schedule is recommended here.

🧴 Liquid suspension formulation: The SC formulation is measured in millilitres for preparation with water. Crop-specific area rates and concentration-based directions remain distinct, which helps avoid applying a fixed bottle quantity regardless of field area or tree canopy size.

Target Crops & Pests

Match the disease to the crop. These are the crop-and-disease combinations in the Amistar leaflet, not an open-ended list of crops that can receive azoxystrobin.

Amistar is not Amistar Top. The latter contains a different combination of active ingredients, so its crop list, rate or use programme must not be transferred to this single-active Azoxystrobin 23% SC product.

Dosage & Application Guide

Confirm the full crop-specific directions before measuring

Do not prepare a treatment from this page alone. No complete current crop-specific Indian Amistar numerical programme is supplied. Confirm crop and disease, crop stage, positive first-treatment conditions, foliar route, formulated-product quantity, carrier-water basis and restrictions together.

The exact branded Indian leaflet identifies the seven retained crop–disease pairings and crop-specific amounts, water and harvest intervals. However, its full positive first-treatment conditions were not established for each crop. Those numerical programme values are withheld together rather than supplied as a partially specified recipe.

The manufacturer’s general flowering-stage statement does not establish a crop-specific first-treatment programme for every listed disease. Its general mixing statement must not replace an area-based rate with a variable water range.

Mango uses a concentration linked to water required by tree size; potato is concentration-based with a specified area-water basis. Other crop rows use area-based product and water quantities. Preserve these distinctions when checking the current pack; do not infer one bottle-per-acre or universal pump recipe.

Use only the complete current Indian Amistar directions, not those of Amistar Top, another azoxystrobin strength or a foreign label. No drone, seed-treatment or drench programme is established here.

No numerical repeat, seasonal maximum, rainfast or worker re-entry programme is supplied. Harvest intervals, repeat-treatment intervals and worker re-entry are different requirements. Missing figures do not mean zero dose, no water or immediate harvest.

How to Apply: Best Practices

• Confirm disease and product identity: Check that the symptom is the labelled disease on the stated crop. Verify Azoxystrobin 23% SC on the pack, not a different Amistar-branded mixture. Similar names do not establish equivalent use directions.
  
• Establish the first-treatment conditions: Confirm the current Indian crop-specific stage and disease conditions before preparing a treatment. A general flowering-stage statement or harvest interval alone does not establish that complete programme.
  
• Keep the quantity basis crop-specific: Obtain the complete current product and water directions before measuring. Keep area-based programmes distinct from orchard concentration and tree-size water requirements; do not confuse active ingredient with formulated product.
  
• Use suitable equipment and full coverage: The leaflet lists knapsack, compression-knapsack, battery-operated and tractor-mounted sprayers. Choose suitable equipment, calibrate its output and ensure that the crop canopy receives thorough coverage without relying on a fixed number of tanks for an unmeasured area.
  
• Prepare the mixture safely: Use clean agricultural measuring equipment rather than cooking utensils and use a stick for stirring, as directed by the leaflet. Avoid contact with skin and eyes and avoid inhaling spray mist or vapour. Do not add a spreader or tank partner without product-specific label support.
  
• Protect the operator and surroundings: Wear gloves, protective clothing, mask, goggles and boots. Keep spray and equipment washings out of water bodies and away from food or feed. Do not eat, drink or smoke during mixing or spraying.
  
• Review disease control responsibly: Keep records of the treatment date and monitor the crop. If control is unsatisfactory, review diagnosis, coverage and resistance risk with a qualified adviser rather than increasing the rate or inventing a short-interval repeat.
