Cartap Effectively Controls Leaf Folder Caterpillars on Rice

1. Overview of Leaf Folder Caterpillars and Their Impact on Rice

The leaf folder is considered one of the most damaging pests for rice in Vietnam. They are present in most rice-growing regions and thrive in humid, high-temperature conditions.

1.1 Characteristics and Life Cycle of Leaf Folders

Leaf folders undergo a complete life cycle with four stages: egg, larva, pupa, and adult. Adult moths lay eggs in clusters on rice leaves, which hatch into larvae within 3–5 days. The larvae pass through five instars over 14–17 days before pupating.

Notably, the first larval instar (4–7 days after mass emergence of adults) is the golden window for spraying Cartap, as larvae are small and most vulnerable to the insecticide at this stage.

1.2 Damage Caused by Leaf Folder Caterpillars

Leaf folders cause damage primarily in the larval stage, using silk to fold rice leaves into tubes and feeding on the chlorophyll-rich tissue. Typical consequences include:

• Reduced photosynthetic area, causing stunted growth
   
• Impaired tillering and overall plant vigor
   
• Fewer grains per panicle and lower grain fill rate
   
• Yield losses of 20–60% if not controlled promptly
   

The most vulnerable growth stages are from tillering to panicle initiation, especially when larval density reaches 6–8 larvae/m².

2. Cartap: The Active Ingredient That Kills Leaf Folders

In the battle against leaf folders, Cartap has demonstrated excellent effectiveness, thanks to its unique mode of action and broad-spectrum control.

2.1 Introduction to Cartap

Cartap Hydrochloride belongs to the Carbamate group, developed from Nereistoxin analogs, a neurotoxin originally isolated from the marine worm Lumbriconereis Heteropoda. Cartap is effective against various crop pests, especially leaf folder caterpillars in rice.

At SATAKA, Cartap is manufactured using advanced technologies that ensure stable active ingredient concentrations and high field efficacy. It is the top choice among farmers for reliable leaf folder control.

2.2 Mode of Action Against Leaf Folder Caterpillars

Cartap eliminates leaf folder caterpillars through two primary modes: ingestion (stomach poison) and contact toxicity. Once inside the pest’s body, Cartap affects the nervous system by:

• Inhibiting nerve impulse transmission by blocking acetylcholine receptors
   
• Causing paralysis of the nervous system, making pests stop feeding and die rapidly
   
• Penetrating plant tissues, allowing it to reach hidden pests inside folded leaves
   
• Killing eggs, larvae, and adults, providing comprehensive pest control
   

A standout feature of Cartap is its dual-effect mechanism: it not only stops pests from causing further damage but also protects crops for an extended period after application.

3. Effectiveness of Cartap in Controlling Leaf Folder Caterpillars on Rice

Cartap is highly valued for its superior effectiveness in managing leaf folder infestations, especially when applied at the correct time and dosage.

3.1 Outstanding Advantages of Cartap in Pest Control

Compared to other leaf folder insecticides, Cartap offers numerous benefits:

• Broad-spectrum control: Effective not only against leaf folders but also brown planthoppers, stem borers, thrips, etc.
   
• High penetration: Quickly enters plant tissues and eradicates hidden caterpillars.
   
• Long-lasting action: Provides protection for up to 7–10 days after application.
   
• Relatively safe: Low toxicity to humans and animals when used correctly.
   
• Protects beneficial insects: Minimal impact on natural enemies.
   

With these strengths, Cartap becomes a top choice in integrated pest management (IPM) programs on rice.

3.2 Optimal Timing for Cartap Application

To achieve maximum effectiveness, timing of Cartap application is crucial:

• Golden window: 5–7 days after peak moth emergence, when larvae are in the first instar.
   
• Critical rice growth stages: Tillering and early heading—when the crop is most vulnerable.
   
• Time of day: Apply early morning or late afternoon when larvae are most active.
   
• Weather conditions: Avoid spraying during rain or extreme heat to ensure maximum efficacy.
   

Proper timing not only enhances pest control but also helps save costs and minimize environmental impact.
