WORLD FIRST FORMULATIONEASY HANDLINGEight years in the making, CRUCIAL is a breakthrough herbicide. It is theonly liquid formulation in the worldwhich combines three glyphosatesalts – potassium, monomethylamineand ammonium. That means moreweed killing power per litre, usingless product per hectare.The world’s most advancedglyphosate makes no compromisewhen it comes to handling andmixing. CRUCIAL pours easily withminimal foam, and tank mixessuperbly with other products. Youalso told us you wanted a lighter,safer pack size, so we made thattoo – CRUCIAL comes in the all-newOHS-friendly 15L pack plus 20L, 110L,200L, 640L and 1000L. All packs canbe recycled through Agrecovery.TRIPLE SURFACTANTTECHNOLOGYTo make sure this unprecedentedload of active ingredient thatequals or exceeds best in classstandards of performance everytime, we’ve created the ultimatemix of complementary on-boardsurfactants. This mix of surfactantsallows the glyphosate molecules tostick and spread rapidly through theplant, giving you the ultimate kill.RESULTS YOU CAN TRUSTWith rapid brownout, excellentefficacy against target plants anda new benchmark in rainfastness,CRUCIAL is purpose-built for consistentresults in our unique and oftenchallenging conditions.TECHNICALLY SUPERIORNo-one in New Zealand knowsglyphosate like Nufarm. We’vebeen in this space for over 30years, with a proud record of localR&D and product development.CRUCIAL comes fully supported byan experienced in field team ofTechnical Specialists and TerritoryManagers, there to support youno matter what.SHORT DOWNTIMEWith CRUCIAL, you can graze,cultivate or drill just one day aftertreatment for annual weeds, andthree days for perennial weeds.Fast turnaround means less downtimebetween spraying and sowing, andmore flexibility especially duringspring and autumn.(Refer to label for silage).

WHERE CAN CRUCIALBE USED?Refer to the CRUCIAL label for specific use recommendations General weed control Brushweed control Agricultural areas Pasture renewal Pasture seedhead suppression (unimproved pastures only) Spraying silage before cutting Spraying hay or silage paddocks after cutting Pre-harvest – wheat, barley, oats, peas Orchards/vines – citrus, apples, pears, stonefruit, kiwifruit, grapevines Industrial and non-agricultural areas Turfgrass and recreational areas Aquatic areas – drains and waterways Forestry Market Gardens Asparagus Spraying out pre and post cropping

HOW TO GET THE BESTOUT OF CRUCIAL Identify target plant species and choose the required rate ofCRUCIAL – for recommended rates refer to the CRUCIAL label. Choose an appropriate tank mixing partnerif required. Ensure target plants are healthy and actively growing, withplenty of leaf area present. CRUCIAL is not absorbed aseffectively when plants are stressed.It also needs plant tissue to land on to do its job. Half fill the spray tank with clean water, add the requiredquantity of CRUCIAL, mix and fill the tank.See the CRUCIAL label for recommended water rates. Add Pulse Penetrant to the full tank,and complete mixing. Apply as a medium even spray to completelycover target plants. Refer to the product label if using tank mix partners.

RAPID TRANSLOCATIONFROM LEAF TO ROOTFor superior control, glyphosate must stick to the surface ofthe leaf, penetrate rapidly, then move quickly into the leavesand roots of the plant. If the plant goes into defensive modeand shuts down before the herbicide is translocated throughits tissue, it can survive being sprayed.CRUCIAL beats this natural defense system through goodadhesion and absorption, fast uptake and excellenttranslocation. A lethal dose is delivered to the foliage,stem and root system even under challenging conditions.UPTAKE AND TRANSLOCATION STUDYTrial NUNZ1867;conducted by Plant Protection Chemistry New Zealand CRUCIAL 2.4L, WeedMaster TS540 2.7L– 1440g glyphosate/100L – dropletsapplied to simulate 100L mix/ha– Pulse Penetrant 100ml/100L Tabu ryegrass grown from seed,5 replicates/treatment Uptake measured 30mins, 2, 6and 24 hours after application Translocation measured 24 hoursafter application Autoradiograph images of plantsto show distribution of glyphosate24hours after treatmentDroplet application site(10 x 0.24μl) on adaxial surface ofthe youngest fully-expanded leaf.

THE POWER OFPULSE PENETRANTAdding Pulse Penetrant to CRUCIAL significantly speedsherbicide uptake in ryegrass. Pulse Penetrant reduces thesurface tension of the spray solution to such a low level thatit is flows easily through stomata (tiny pores in the leaf).In spring, the waxy cuticle on the ryegrass leaf surfacethickens. Without Pulse Penetrant glyphosate cannoteffectively penetrate this thick waxy layer.Uptake is reduced which then results in poor control.

RAINFAST IN 15 MINUTESWITH PULSE PENETRANTCRUCIAL tank mixed with Pulse Penetrant should deliver commerciallyacceptable weed control even if light rain occurs just 15 minutes afterspraying. No other glyphosate can match this standard.

HIGH STRENGTH EFFICIENCYCRUCIAL’s high strength formulation means lower application rates perhectare; smaller volumes to purchase, transport and store; and fewer emptycontainers to recycle. After mixing, CRUCIAL remains stable in the tank for fivedays with good water quality so you don’t have to start again with a new mixif the weather interferes with spraying. Note: Pulse Penetrant will break downin water, so if the mixture contained Pulse Penetrant and it has been storedovernight or longer Pulse Penetrant will need to be re-added. Tank mixes ofCRUCIAL and other products should be used promptly.CRUCIAL: EFFICACY – PERENNIAL RYEGRASS IN SPRING% Brownout100% 0111620254Days after applicationWeedMaster TS540 2.7L6810151719Days after applicationCRUCIAL 2.4LWeedMaster TS540 2.7LRoundup Ultra Max 2.5LCRUCIAL 2.4LRoundup Ultra Max 2.5LTrial NUNZ1749Trial NUNZ1750 No re-growth in any plot No re-growth in any plot All with Pulse Penetrant 100ml/100L All with Pulse Penetrant 100ml/100L Established perennial ryegrass pasture,sprayed 23 Sep 2017 Established perennial ryegrass pasture,sprayed 14 Oct 2017 Grazed 3 days after spraying Not grazed after spraying
