Horn Silica (BD 501) | Instructions for Use on Foliage
What you need:
- 3 gallons of lukewarm rainwater (or chemical free water) for every 1 unit of BD 501.
- A clean container large enough to prevent splashing out (chemical-free). A light-weight, but strong stick.
Directions:
Stir vigorously in one direction until liquid forms a deep crater. Quickly reverse direction and repeat. Continue this alteration every minute or so for one full hour. Use immediately.
Spraying:
- Spray in the morning, just as the sun is touching the leaves.
- Spray as soon as possible after stirring; it deteriorates rapidly if left standing. Use an ordinary sprayer for a fine mist spray.
- Spray on foliage – but it will do no harm to soil.
- Cover one acre per unit.
- Always use chemical-free, clean utensils.
Storage:
- Keep in any dry or sunny place until used.
- It keeps indefinitely if dry. Spray only on areas where 500 has been used previously.
When to use:
- Only after plant roots are well established.
- Use as early in the morning as possible.
- Use when there is no wind.
- Use with seedlings, when 2nd or 3rd leaves have unfolded.
- Use only following blossoms on trees or shrubs, before leaf growth. Use on foliage emergencies—when diseases or pests have destroyed much foliage.
- Usually in late spring or early summer when warm weather is well established.
- Never when there is a danger of frost.
- Never just before a rain.
- Never before transplanting.
- Never use on young evergreens and fruit trees. You can use when they are of bearing age.
- Use especially during wet seasons with too little sunshine.
- Use indoors or in greenhouses during the shortest days of the year.
