tried all none toxic options

Here again. Luckily this run I've found only two of these worms. If U don't have an invasion the only way to fight them is "manual fight". Two ways: preventive fight consists of checking the buds one by one waiting fight consists to remove the worm and its sticky nest once U recognise the death sugar leaves (this symptom is equal to first sign of bud rot). PS In your future runs consider to use a pyrethroid until the beginning of flowering such as Deltamethryn, broad spectrum pesticide. It will protect plants up to 20 days after the last application. This pesticide is the most used in agriculture and is considered to be the safest for health (how can a poison be safe for health?) and for the plant itself.
