₹850.00

Rallis Clasto (Pyrifluquinazon 20% WG) – Product Overview

Rallis Clasto is a cutting-edge, next-generation insecticide featuring the active ingredient Pyrifluquinazon 20% WG (Wettable Granules). It belongs to a unique chemical class (Pyridine azomethine derivatives) specifically developed to manage tough-to-kill sucking pests. Clasto is highly regarded for its ability to provide long-lasting relief in crops where pests have developed resistance to traditional neonicotinoids.

Key Features & Mode of Action

  • Unique Behavior Modifier: Clasto works as an "anti-feedant." It immediately disrupts the coordination and feeding behavior of sucking pests. Once exposed, the insects cannot insert their mouthparts into the plant tissue and eventually die of dehydration and starvation.

  • Immediate Protection: Although the pest may stay on the plant for a short time after spraying, it stops feeding instantly, halting any further crop damage or virus transmission.

  • Excellent Translaminar Activity: The product moves from the upper surface of the leaf to the lower surface, targeting pests hiding in hard-to-reach areas.

  • Advanced WG Formulation: The Water Dispersible Granule (WG) format ensures easy measurement, no dust, and excellent solubility in water.

Recommended Uses on Various Crops

Clasto is a specialist for sucking pest complexes, especially in vegetables and fiber crops.

Key Benefits

  1. Breaking Resistance: It is a powerful tool against Whiteflies and Thrips that no longer respond to older insecticidal sprays.

  2. Extended Residual Control: Provides a long window of protection (often up to 15–20 days), reducing the number of sprays required per season.

  3. Virus Management: By instantly stopping sucking pests (which are often carriers of plant viruses like Chilli Leaf Curl), Clasto helps in maintaining the overall health of the field.

  4. Rain-Fastness: Strong translaminar movement means the product is quickly absorbed into the leaf, making it less likely to wash away.

Application & Safety Guidelines

  • Application Stage: For best results, apply Clasto at the early stages of pest population buildup. It is highly effective during the vegetative and flowering stages.

  • Water Volume: Use 150–200 liters of water per acre to ensure uniform and thorough coverage of the foliage.

  • IPM Friendly: Clasto has a selective mode of action that is generally safer for many beneficial predatory insects compared to broad-spectrum pyrethroids.

  • Safety: Always wear protective gear, including gloves and a face shield. Do not spray against the direction of the wind.
