IntroductionIntroduction
PASS-HB spray adjuvant is a polyether modified
trisiloxane based wetting agent, especialy used for
systemic herbicides which needs good spreading
ability as well as longer retention time on foliar
surface, like Glyphosate and so on.
PASS-HB is used to enhance efficacy of herbicides
relative to conventional adjuvants like tallow amine
ethoxylate based adjuvants.
Specification
Active content: 100%
Appearance: transparent light amber liquid
Surface tension (0.1%): < 21 mN/m
Viscosity: 40-80 mPa.s
Field test report
Test conditions:Humidity:70-80% Temperature: 22-28℃Spray and record time: 2:30-3:00 PM (Sep, 2014)
Weeds to control:Digitaria sanguinalis (L.) Scop in outside turf, Shanghai, China
Spraying solutions PH≈4:1. Water for reference2. Glyphosate 747 SG 5g/L in water3. Glyphosate 747SG 5g/L with PASS-HB 1g/L in water

Field test reportRecords on spraying day (SEP 4th, 2014)
Sprayed with 5g/L Glyphosate 747SG+1g/L PASS-HB
Sprayed with 5g/L Glyphosate 747SG
With Glyphosate only: most drops slided down to the ground, and weedscan’t be covered by droplets evenly.
With Glyphosate + PASS-HB: weeds were totally wetted and covered bydroplets. And uptake of droplets much faster decreased time of absorbing,which will make it better rainfastness.

Field records (from SEP 5th -17th, 2014)
With Glyphosate only: need 13days to kill all weedsWith Glyphosate + PASS-HB: only 6 days all weeds can be killed

Field test report
Field test result:
1. Glyphosate is effective to controlDigitaria sanguinalis (L.) Scop weed inturf.
2. PASS-HB can increase coverage area ofGlyphosate droplets on weeds.
3. PASS-HB can shorter effect time ofGlyphosate on tested weeds, almosthalf time. Glyphosate-13days, when plusPASS-HB-only 6 days.
4. PASS-HB can increase efficacy ofGlyphosate in tested weed control.

Cost Performance
Spraying Only Glyphosate
Takes me to make sure all weeds covered
Droplets slide down to the ground cause waste
Long me to control the weeds
Slow uptake, easily to be rushed by rain a er spraying
Spraying Glyphosate + PASS-HB
Easy to use, and can cover almost all weeds
May decrease spraying volume to get same result
Very small quan ty slide down to ground
Increase spraying ra o
Shorter almost half me of weed control
Save half me to wait weeds killed
Quick uptake, can be rainfastness30mins a er spraying
Solve problem when we meet rainny days

Only very small dosage of PASS-HB, we can get: Time saved, better efficacy & rainfastness.
Also may get spray volume saved.
