GSP Across X Insecticide (Pymetrozine 50% WG) is a selective systemic insecticide developed mainly for the management of brown plant hopper (BPH) in paddy. It works as a specialized feeding blocker, helping stop sap-feeding activity soon after susceptible hoppers are exposed.
Across X is based on Pymetrozine 50% WG, a water-dispersible granule formulation known for its selective action against important sucking pests. It is particularly useful in paddy where brown plant hoppers gather near the base of plants and continuously remove sap from the crop.

Pymetrozine is a selective systemic insecticide that acts mainly as a feeding blocker. It interferes with the normal feeding mechanism of susceptible sucking pests, causing them to stop feeding on the crop.
Once feeding stops, further sap removal and crop injury are reduced. This mode of action is especially useful against planthoppers and similar sap-feeding pests.
Brown plant hopper is an important sucking pest of paddy. Large populations may gather near the base of rice plants and continuously suck plant sap.
Severe infestation can cause yellowing, drying and characteristic hopper-burn patches in the field. Early application of Across X can help reduce feeding activity before pest pressure becomes severe.
Hopper burn generally develops when brown plant hopper populations become high and feed continuously on rice plants. Affected areas may turn yellow, then brown and dry rapidly.
Field monitoring and timely insecticide application are important because treatment before heavy hopper-burn develops generally provides better crop protection.
Apply Across X when brown plant hopper is first noticed or when field scouting shows the pest population is increasing toward the recommended treatment threshold.
Do not wait until severe hopper burn has developed. Early or moderate pest pressure is generally a better stage for intervention.
Pymetrozine has a specialized mode of action and can be useful within an integrated pest-management program. Field scouting, economic threshold-based spraying and conservation of beneficial organisms can help improve long-term hopper management.
Where repeated insecticide treatments are required, rotate Across X with suitable products having different IRAC mode-of-action groups.
GSP Across X is a selective systemic insecticide containing Pymetrozine 50% WG, mainly used for brown plant hopper management in paddy.
Across X contains Pymetrozine 50% WG.
It is mainly recommended for brown plant hopper in paddy.
The common field dose is approximately 120 g per acre according to the referenced product information.
The referenced rate is approximately 0.8 g per litre when used with the recommended spray-water volume.
Yes. Across X is described as a systemic insecticide.
Pymetrozine disrupts the normal feeding mechanism of susceptible sucking pests, causing them to stop feeding on crop sap.
The referenced pre-harvest interval is 19 days for paddy. Always confirm this on the current product label.
Give good coverage to the lower crop canopy and plant base because brown plant hoppers frequently remain near the lower portions of rice plants.
Yes. By reducing brown plant hopper feeding pressure, timely application can help lower the risk of hopper-burn symptoms.
Yes. Its selective and specialized mode of action makes it suitable for integration into a planned IPM program.
No. Use it only on crops and pests specifically listed on the current registered product label.
GSP Across X Insecticide (Pymetrozine 50% WG) is a selective systemic feeding-blocker insecticide for management of brown plant hopper in paddy. Correct dosage, early application and good spray coverage around the lower rice canopy are important for effective pest management.
