is it possible to use non micronised powder type sulphur as effective foliar pesticide in veg? Would the micronisation of the powder bring any advantage except that eat dissolve more fastly?
I only have access to non micronised sulphur, that is why Im asking
thank you guys

Based on this yes.


Micronised and non‐micronised sulphur applications control peach scab equally well with negligible differences in fruit quality
Abstract
In a 2‐year study, micronised (finely ground) and non‐micronised sulphur spray programmes were investigated for peach scab control and influence on peach fruit quality variables including fruit colouration, soluble solids content and flesh firmness. Both sulphur programmes, applied six or 11 times at 15 kg ha−1, controlled scab equally well in both years on cultivars (cvs) Contender and Cresthaven. Six applications of a half dosage of both micronised and non‐micronised sulphur programmes were significantly less effective (P < 0.05) compared with all other programmes when scab incidence was >90% on cv. Contender. None of the sulphur programmes influenced significantly (P < 0.05) colouration and flesh firmness of harvested fruits compared with the industry standard (a chlorothalonil–captan programme)


I don't see why cannabis should be any different.

I use Lilly Miller brand Sulfur dust, no idea if it is micronized or not but it doesnt mix that easily with water, though i still use it as a spray...however, it is extremely effective for broad/spider/russet mites and I think i spent less than $10 and its lasted me a few years.

Thx very much I can buy liquid concentrate solution, for quite cheap, but I must find out what wetting agent is used and if there are any more additives

Nothing but I'd probably look into predator mites if they were legal to import into Hawaii.

I use a combo of regalia and grandevo until week 2-3 of flower and hope that holds me over until finish. Both are expensive but organic and approved for use on cannabis in oregon and california. Removing yellow/dead leaves and keeping your grow space tidy helps alot, my mini greenhouse has tiled floor with a floor drain, so I try to mop it and rinse it down periodically.

I use an hudson atomizer and it gives great coverage while using minimal amount of liquid. 1 gallon of liquid can cover my whole garden plus surrounding vegetation. Alternatively, you can look into electric paint sprayers that work equally well. One of the most important things with any mite treatment, is ensuring you get as close to 100% coverage as possible.

Hi I got this already emulsified ready to use foliar which contains inorganic sulphur min 19% from that polysulfide sulphur is 14% minumum and calcium content is min 8, ph of the concentrate is 9-11 Im wondering if this might work

I was thinking about getting some better said farming them, there are some techniques here on web+

Thank you for recommending me the paint sprayer, just bought one, atomizes really well, now Im wondering if I can use this sollution effectively and what would be the good dosage it haveinorganic sulphur min 19% from that polysulfide sulphur is 14% minumum and calcium content is min 8, ph of the concentrate is 9-11
