Key takeawaysముఖ్యాంశాలుमुख्य बातें
- Spray early morning or late evening, when it is cool and leaves are open to absorb.
- Cover both sides of the leaf with a fine mist.
- Always do a jar test before mixing two or more products.
- Never exceed the label dose.
- Wear protective clothing and keep products away from children.
Why foliar spraying is used
Foliar spraying delivers small amounts of nutrients or bio stimulants directly to the leaves, which is useful when the crop needs a quick correction or when soil conditions limit uptake, such as zinc in alkaline soils.
Step-by-step method for effective spraying
Step 1: Choose the right time
Spray in the early morning or late evening. Avoid midday sun, strong wind and the hours before rain.
Step 2: Prepare the solution properly
- Use clean water, ideally not very hard or salty.
- Fill the tank halfway, add the product, then top up with water while stirring.
- Prepare only what you can spray the same day.
What is a jar test?
Mix small proportional amounts of each product in a bottle of water. If it clumps, separates, heats up or forms flakes, do not mix them in the tank.
Step 3: Use the right nozzle and coverage
A fine mist covering the upper and lower leaf surface works better than heavy drenching. Stop when the leaves are just wet, before the liquid starts dripping.
Common foliar spray mistakes
- Spraying in strong sun, which causes burn and fast drying.
- Using a higher dose to get faster results.
- Mixing many products at once without testing.
- Skipping a sticker-spreader when the label recommends one, as for boron.
- Not cleaning the sprayer between products.
Safety checklist
- Wear gloves, mask and full-sleeve clothes.
- Do not eat, drink or smoke while spraying.
- Wash hands and face after spraying.
- Store products in the original pack, away from food and children.
FAQs: Foliar Spray Guide
What is the best time of day for a foliar spray?
Early morning, after the dew has started to dry, or late evening is best. At these times temperature is lower, leaf pores are open and the spray stays wet longer, so more of the nutrient is absorbed. Avoid spraying if rain is expected within a few hours because it can wash the product off the leaves.
Do I need to add a sticker or spreader?
Only when the label recommends it or when leaves are waxy and the droplets roll off. For example, Navasiri Boron 20% suggests adding a sticker-spreader. Use the dose written by the sticker manufacturer, as too much can cause leaf damage.
Can I mix bio stimulants with pesticides?
Some combinations are compatible and others are not. Check the labels and do a jar test. If you see clumping or separation, spray the products separately with a gap of at least a day.
How long after spraying will the crop show a response?
It depends on the nutrient and the crop. Some deficiency symptoms begin to improve in new growth within a week or two. Damaged tissue does not fully recover, so the aim is to prevent loss early rather than wait until symptoms are severe.
