What Cartap Hydrochloride 4% GR Is
Cartap hydrochloride is a broad-spectrum, systemic insecticide derived from nereistoxin. It is known for its strong activity against chewing insects, especially stem borers, leaf folders and other internal feeders.
In this product, the active ingredient is formulated as:
-
Active ingredient: Cartap hydrochloride 4%
-
Formulation type: GR – Granules (Granular insecticide)
Key characteristics of the 4% GR formulation:
-
Low-dose, ready-to-use granules
-
Designed for soil application, paddy broadcasting or root zone placement
-
No need for tank mixing or complex preparation in the field
-
Suitable for farmers who prefer simple, mechanical or manual broadcasting
By focusing on 4% granules, this product targets markets and grower segments where ease of use and broad coverage are more important than high-concentration spray formulations.
Use Scenarios and Field Positioning
Cartap Hydrochloride 4% GR is intended for field crops where soil or water-based application is appropriate, such as:
-
Paddy rice under flooded conditions, where granules can be broadcast into the water or onto the soil surface as per local label
-
Field soils where target pests attack the root zone, basal stem or underground parts of the plant, depending on registration
-
Situations where spraying is difficult due to labour, equipment or field conditions, and growers prefer a “spread-and-go” solution
Typical positioning:
-
A granular insecticide for controlling stem borers and similar pests in rice paddies
-
A complement or alternative to sprayable formulations such as SP, SC or EC
-
Suitable for regions with smallholders using manual broadcasting as well as larger farms using mechanical granule applicators
The actual crop list, timing and placement method must strictly follow local registrations and approved labels.
Mode of Action and Spectrum of Activity
Cartap hydrochloride acts through contact and stomach action, and it also shows systemic activity in plants.
Mode of action in simple terms:
-
The insect picks up the granules or the dissolved active ingredient from the soil or water environment, or by feeding on treated plant tissue.
-
Cartap affects the insect’s nervous system, disrupting the transmission of nerve impulses.
-
The pest stops feeding, shows reduced movement and gradually dies.
Because of this, cartap hydrochloride 4% GR is especially effective for:
-
Stem borers and internal feeders that live in stems or near the plant base
-
Root zone and soil-dwelling larvae that feed on underground plant parts
-
Early-stage infestations where larvae are still sensitive to systemic and stomach poisons
The granular formulation allows the active ingredient to:
-
Dissolve gradually in soil water or floodwater
-
Move into the root zone and be taken up by the plant, providing systemic protection
-
Contact larvae and other pests in the water or soil interface
This combination of soil / water contact + plant systemic activity makes 4% GR a flexible tool for many rice-focused insect control programmes.
Advantages of 4% Granular Formulation vs Sprayable Types
Compared with higher-concentration SP, SC or EC formulations, a 4% GR (granule) offers several practical advantages in the field.
Ease of use
-
No need for mixing in a spray tank
-
Can be applied directly by broadcasting by hand or with simple equipment
-
Suitable for areas with limited access to spraying machinery or clean water
Field coverage and efficiency
-
Granules can reach areas of the field that are difficult to spray, especially in flooded rice paddies or uneven terrain
-
More uniform distribution in water or soil when applied correctly
-
Can be applied during normal field operations with minimal interruption
Safety and handling
-
Lower risk of spray drift compared to foliar sprays
-
Reduced operator exposure to fine droplets or aerosols
-
Easy to package, ship and store, with less risk of spillage
Fit for paddy and soil pests
-
Designed to work where pests are in or near the soil and water, not only on the leaf surface
-
Good for controlling pests that are hard to reach with contact sprays alone
For distributors and brand owners, these advantages make cartap hydrochloride 4% GR an attractive option in markets where paddy rice and field soils are key segments and where broadcasting is standard practice.
Application Principles for Cartap 4% GR
The exact application rates, timing and method must always follow your national label and local regulations. However, the general principles are:
-
Use preventively or at the early stage of pest infestation, when larvae are small and more sensitive.
-
Apply by broadcasting granules uniformly over the field or paddy area, as specified for each crop and pest on the label.
-
In paddy systems, the water level and timing of irrigation or drainage should follow local agronomic and label recommendations to ensure proper distribution and movement of the active ingredient.
-
Ensure the field surface is prepared so that the granules can spread evenly and not accumulate excessively in one area.
-
Integrate cartap 4% GR into a broader insect management programme, including monitoring, thresholds and rotation with other insecticide groups to manage resistance.
Because granular products are not sprayed, they are particularly suitable for farms where sprayer availability, water quality or labour limit the use of liquid formulations.

Frequently Asked Questions (FAQ)
What is Cartap Hydrochloride 4% GR used for?
It is a granular insecticide used for controlling soil and paddy-field pests, especially chewing and boring insects such as stem borers, depending on local label approvals. It is applied by broadcasting granules instead of spraying.
How is a 4% GR different from higher-concentration spray formulations?
A 4% GR is a ready-to-use solid granule. It is designed for soil or water-based broadcasting, with no tank mixing. Higher-concentration formulations such as SP, SC or EC are liquid or powder products that must be mixed with water and sprayed. Granules are easier to apply in paddy fields and where spraying is difficult.
Is Cartap 4% GR systemic?
Cartap has systemic properties. When the active ingredient is taken up by plant roots, it can move inside the plant and protect tissue against certain pests. It also has contact and stomach action on insects directly exposed to the treated soil or water.
Can Cartap 4% GR be mixed with fertiliser or other products?
In some programmes, granules may be applied at the same time as fertiliser or other soil treatments, but any combination must respect local regulations and label instructions. Physical and agronomic compatibility should be tested on a small scale first.
Is Cartap Hydrochloride 4% GR safe for all crops?
No. Like all insecticides, Cartap 4% GR must only be used on crops and at timings that are registered and allowed in the target country. Always follow the local label for crop list, rates, timings and restrictions.
