When & How to Apply Agricultural Products
When & How to Apply Agricultural Products Choosing the right agricultural product is important — but how and when you apply it can be equally important. Different products are designed for different purposes. Some are used for seed treatment, some around the root zone, some through drip irrigation, while others are applied as foliar sprays. Similarly, the recommended timing can vary according to the crop’s growth stage. For example, a product intended for seed treatment should not simply be treated like a foliar spray, while a flowering-stage product may have a completely different application window. This guide explains the basic application approaches used across the PhourAgro product range and why following the recommended method and timing matters. Why Application Method Matters Agricultural products can be applied through different methods depending on their formulation and intended use. The main methods found across the PhourAgro range include: 🌱 Seed Treatment Applied directly to seeds before sowing. 🌿 Soil Application Applied to the soil or root zone. 💧 Drip / Fertigation Delivered through irrigation systems. 🍃 Foliar Spray Applied directly to plant foliage. 🌳 Root Zone Application Placed around the root area of established plants or trees. The appropriate method depends on the individual product. 1. Seed Treatment Seed treatment is one of the earliest opportunities to support crop establishment. The purpose is to treat the seed before it is planted so that the product is present from the beginning of the crop cycle. Phour Bioteeka Phour Bioteeka is positioned as a Seed Specialist and is listed for cereals, pulses, oilseeds and vegetables. The catalogue recommends seed coating/slurry application. Listed rates include: Application Stage Before sowing This makes seed treatment a starting point in the crop-growth journey. 2. Soil & Root-Zone Application Some products are intended to be applied directly to soil or around the root zone. This approach is particularly relevant for products focused on soil health and root development. Phour Mycorrhiza Phour Mycorrhiza is listed for cereals, pulses, oilseeds, vegetables, fruits and plantation crops. The catalogue lists: It is positioned around the root–soil interface and nutrient absorption. Application Methods 3. Soil Application for Soil Health Soil-focused products can be incorporated into the crop-management process before or around planting. Phour Black Gold Phour Black Gold is listed as a Phosphate Rich Organic Manure (PROM). The catalogue recommends basal soil application before sowing or transplanting. Listed application rates: Cereals & Pulses 50 kg/acre Vegetables 40 kg/acre Fruit Orchards 2–5 kg/tree, depending on tree age. This demonstrates an important principle: Application rate can change according to the crop and growing system. 4. Drip & Fertigation Application Some products can be delivered through irrigation systems. This can be useful when the product’s formulation and label specifically support drip or fertigation application. Phour Azotobacter + PSB The catalogue lists seed treatment, soil drench and drip application among its application methods. Listed examples include: Important The catalogue specifically states to avoid direct mixing with chemical fertilizers and pesticides for this product. Always follow the final approved product label for compatibility instructions. 5. Foliar Spray Foliar application means applying the product directly to plant foliage through a spray. This method is used for several PhourAgro products where the catalogue specifically recommends foliar application. Phour Zinc Power Phour Zinc Power is a liquid chelated zinc product containing 12% EDTA-chelated Zn. It is listed for cereals, vegetables and fruits with zinc deficiency. The catalogue lists: Application is listed as foliar spray from the vegetative to flowering stage, depending on the crop. 6. Application According to Crop Stage One of the most important factors in product application is timing. A product can have a specific recommended crop stage. For example: 🌱 Vegetative Stage Phour Azoteeka Plus-E The catalogue lists foliar, soil drench and drip application and positions it around vegetative growth. 🌸 Flowering Stage Phour Bhoomi-K Listed from flowering through fruit ripening depending on the crop. 🌾 Grain / Pod Development Phour Up-Gro Listed for wheat and pulses from flowering to grain/pod filling. This is why the same product should not automatically be applied at every stage of the crop. 7. Paddy-Specific Application Some products are designed specifically around a crop. Phour Paddy Booster Phour Paddy Booster is listed specifically for paddy and is described as a liquid NPK + micronutrient complex. The catalogue lists: Tillering 500 ml/acre Panicle Initiation 300 ml/acre Application method: Foliar spray This is a good example of crop-specific + stage-specific application. 8. NPK Application Phour N.P.K. is available in: and is described as 100% water soluble in the catalogue. The catalogue positions: 19:19:19 For the vegetative stage Listed fertigation rate: 3–4 kg/acre every 10–15 days 0:52:34 For the flowering to fruit/grain stage Listed rate: 2–3 kg/acre The exact application should always follow the approved product label and crop-specific recommendation. 9. Root-Zone Application for Horticulture Horticultural crops and fruit trees may require a different application approach from field crops. Phour RootMax RootMax is listed for: The catalogue recommends root-zone/nursery-mix application. Examples include: New fruit plants: 200–300 g/pit Nursery & ornamentals: 50–100 g/plant or pot Horticulture field crops: 3–4 kg/acre Application Method at a Glance Application Method Example Product Typical Use Seed Treatment Bioteeka Before sowing Soil Application Black Gold Before sowing/transplanting Root Application Mycorrhiza Sowing/transplanting Drip Azotobacter + PSB Crop/soil support Foliar Spray Zinc Power Vegetative–flowering Stage-Specific Spray Paddy Booster Tillering/panicle initiation Root Zone RootMax Horticulture How to Choose the Right Application Method Before applying any product, ask these five questions: 01 — What Crop Am I Growing? Wheat, paddy, vegetables, pulses and fruit crops can have different requirements. 02 — What Stage Is the Crop In? Seed, root development, vegetative growth, flowering or fruit/grain development? 03 — What Is the Product Designed For? Check the product’s intended use and recommended crops. 04 — Which Application Method Is Recommended? Seed treatment, soil application, drip, foliar spray or root-zone application? 05 — What Is the Recommended Dosage? Never assume that the same dosage applies to every crop or application method. Don’t Overlook Product Compatibility Another important part
