Spinosad and Spinetoram, belonging to Group 5 (Spinosyns) according to the Insecticide Resistance Action Committee (IRAC), are highly effective against Spodoptera frugiperda (fall armyworm). These insecticides are derived from the bacterium Saccharopolyspora spinosa and are widely used in integrated pest management (IPM) programs.

Mode of Action
Both Spinosad and Spinetoram act on the nicotinic acetylcholine receptors (nAChRs) and GABA-gated chloride channels in the nervous system of insects.

This dual action results in excitation of the nervous system, leading to paralysis and eventual death of the larvae

Key Features

1. Broad-Spectrum Activity: Effective against lepidopteran pests like fall armyworm as well as other insects such as thrips and fruit flies.


2. High Efficacy on Larvae: Particularly effective on small to medium-sized larvae of Spodoptera species.


3. Low Residual Toxicity: Safe for many beneficial insects like pollinators and natural predators when used correctly.


4. Environmentally Friendly: Classified as reduced-risk insecticides, making them suitable for organic farming (Spinosad in particular)

Application Guidelines

1. Timing: Apply at the early stages of infestation, ideally when larvae are small (1st or 2nd instar), to prevent severe crop damage.

2. Dosage: Follow label instructions; common application rates range from 0.1 to 0.2 g active ingredient per liter, depending on crop type and pest severity.


3. Application Method:

Use as a foliar spray to ensure thorough coverage, particularly in leaf whorls and other hiding spots.

Spinetoram provides longer residual activity than Spinosad, requiring fewer applications.


4. Compatibility: Compatible with most fungicides and other insecticides, but avoid mixing with alkaline substances

Resistance Management

Alternate Spinosad/Spinetoram with insecticides from other IRAC groups (e.g., chlorantraniliprole (Group 28) or emamectin benzoate (Group 6)) to prevent resistance buildup.

Use in conjunction with cultural and biological controls for sustainable pest management

Precautions

Avoid spraying during peak pollination periods to minimize risks to bees.

Always wear personal protective equipment (PPE) during application.

Store and handle these insecticides according to safety guidelines.

By integrating Spinosad or Spinetoram into a well-planned pest management program, you can effectively control Spodoptera frugiperda while maintaining environmental and ecological balance.
