Boom Flower Bio-Stimulant: Nitrobenzene Flowering & Yield

Boom Flower is an agricultural bio-stimulant and plant energizer manufactured by Devi Crops containing Nitrobenzene (20% w/w). Formulated to stimulate floral bud initiation, prevent premature flower and fruit drop, and enhance fruit set across field, vegetable, and horticultural crops.

Chemical Nature and Physiological Plant Response

Nitrobenzene operates as a plant bio-energizer and metabolic stimulant. It stimulates the plant's internal enzymatic pathways, promoting cell division and enhancing the synthesis of natural hormones involved in the floral transition.

By accelerating nutrient absorption and protein synthesis, Boom Flower redirects photosynthates toward flower bud initiation, transforming vegetative shoots into productive reproductive branches.

  • Floral Bud Induction: Stimulates vegetative buds to differentiate into flowering primordia.
  • Reducing Flower Drop: Strengthens pedicel attachments, preventing blossom abortion during temperature fluctuations.
  • Fruit Set Enhancement: Improves pollen viability and accelerates post-pollination fruitlet growth.

Target Crops and Application Stages

Boom Flower is widely applied across flowering crops including cotton, chilli, tomato, brinjal, mango, pomegranate, and pulses (chickpea and pigeon pea).

In cotton, it promotes square development and reduces flower shedding; in chilli and tomato, it promotes continuous flower flushes and uniform fruit development; and in mango orchards, it improves blossom retention.

  • Cotton Farming: Increases square and boll retention per plant, leading to higher lint harvests.
  • Chilli & Vegetables: Promotes uniform flowering flushes and prevents flower drop caused by heat stress.
  • Fruit Orchards: Enhances post-bloom fruitlet retention in mango, pomegranate, and citrus.

Application Guidelines and Spray Timing

Apply Boom Flower as a foliar spray at critical phenological growth stages: first application at vegetative growth before flower bud initiation, second spray at peak flowering, and third spray during early fruit development.

Maintain recommended dilution rates (typically 2 to 3 ml per liter of water) and apply during calm morning or late afternoon hours with adequate soil moisture. Compatible with commonly used non-alkaline insecticides and fungicides.

  • Optimal Timing: Spray at pre-flowering and peak flowering stages for maximum bloom enhancement.
  • Soil Moisture Requirement: Ensure the crop is well-irrigated before spraying.
  • Tank Mix Compatibility: Can be combined with standard pest protection sprays to reduce operational costs.
