Use Foliar Spray for Effective Plant Care

A foliar sprayer is equipment used to apply liquid nutrients, fertilizers, pesticides, or other approved crop inputs directly onto plant leaves. In agriculture, sprayers may be handheld, tractor-mounted, or drone-based. Leher uses agricultural drones for foliar spraying, helping deliver fine, even coverage across crop foliage while reducing manual effort, water use, and operator exposure.

Foliar spray is used to deliver nutrients and crop-care inputs directly to plant leaves for faster absorption. Farmers commonly use it for correcting nutrient deficiencies, supporting crop growth during key stages, improving plant resilience, and applying compatible pesticides or weedicides. Drone-based foliar spraying helps cover large fields uniformly, especially where manual spraying is slow or difficult.

Foliar spray is usually most effective when plants can absorb the solution without heat stress or rapid evaporation. Farmers often prefer cooler parts of the day, such as morning or late afternoon, while avoiding strong wind or rain. The crop stage, product label, and leaf condition should guide timing so nutrients reach the foliage efficiently.

Drone foliar spraying improves plant care by applying nutrients evenly across the crop canopy with controlled dosage and reduced wastage. It can cover large areas quickly, avoid crop trampling, and reduce water usage by around 90%. For crops like paddy, cotton, wheat, sugarcane, and vegetables, drones help make timely spraying more practical and consistent.

Leher supports foliar and crop spraying for several crops, including paddy, cotton, wheat, sugarcane, vegetables, tea, and rubber plantations. The suitability depends on crop height, growth stage, field layout, and the product being applied. Drone spraying is especially useful for dense, wet, tall, or large fields where ground application is inefficient.

Foliar spray is safe for plants when the right product, dosage, dilution, and timing are used. Because leaves absorb inputs quickly, overly strong mixtures or spraying during harsh heat can cause stress. Leher’s drone spraying approach focuses on precise application and uniform coverage, helping reduce overuse while supporting effective nutrient delivery.

Farmers can book drone spraying through the Leher App. After booking, a trained drone pilot is dispatched to the farm to complete the spraying session. The app supports scheduling, service coordination, payment after job completion, and spraying-history records, making it easier for farmers to manage recurring crop-care applications.

Compared with manual spraying, Leher’s drone-based approach offers faster field coverage, more uniform application, reduced operator chemical exposure, and major water savings. The core agriculture drone spraying service can cover up to 50 acres per day and helps reduce input use, making foliar plant care more efficient for farmers and agribusinesses.
