The program

An open-field crop, built for strong establishment and high-quality, straight fruit.

Agroperfect developed this integrated open-field cucumber program to support strong crop establishment, balanced growth, stable production, and high fruit quality — combining stage-based nutrition with effective crop protection across the whole season.

Nutrition is timed to each growth stage, from establishment through vegetative growth, flowering, fruit set, and full production; protection runs alongside it, holding back the weeds, diseases, and insects that most affect the crop and its fruit.

Two tracks, one calendar

How the program is built

Nutrition and crop protection run in parallel through the same growth stages — so feeding the crop and defending it are planned as one schedule, from establishment through full production.

Nutrition program

Establish strong, then build the fruit

Open the season with NPK and poly sulphate plus salinity management and chelated iron for strong establishment, then drive vegetative growth with high-phosphorus foliar nutrition, magnesium, and micronutrients. Position boron and calcium around flowering to secure fruit set, then carry potassium-rich, calcium-magnesium nutrition through fruiting and production — finishing with high-potassium amino-acid feed under heavy load for stable yield and quality.

Crop protection program

Protect from seed to harvest

Start at the seed with treatment against soil-borne disease, then clear weed competition before and after emergence. Open the disease-control window ahead of flowering — when downy and powdery mildew do most damage — and layer in insect control against aphids, whiteflies, and mites as pressure builds, with every application matched to field conditions to protect the canopy, the flowers, and final fruit quality.

Built for the harvest

Every stage points toward stable production & quality fruit

A crop that establishes strong, stays balanced, and is well protected sets and fills full, clean, straight fruit. From the first true leaves onward, the program is tuned to convert crop vigor into stable production and high fruit quality.

The season, stage by stage

Season roadmap

Each growth stage below shows both tracks together — what to feed the crop, and what to protect it from — so the whole season reads as one plan.

Nutrition Crop protection

Establishment

Sowing & emergence

Set up strong roots and even emergence, protect the seed, and clear weeds before the crop is up.

Nutrition

NPK + Poly Sulphate Balanced base nutrition with sulphur, magnesium, and calcium to drive root development and strong establishment.

SALINITYFIX Manages soil and water salinity early so young roots establish freely in difficult conditions.

Chelated Iron Prevents early iron chlorosis and keeps emerging seedlings green and active.

Crop protection

Seed treatmentTESTRA Protects the seed and seedling against soil-borne disease and damping-off for even, healthy emergence.

Weeds · pre-emCAMPSU 960 EC Pre-emergence weed control to remove competition before the crop establishes.

Vegetative Growth

Active growth

Build a strong vine and canopy, finish weed control after emergence, and open the insect window.

Nutrition

FOLIAFERT 10-52-10 + TE High-phosphorus foliar feed to drive root activity, energy transfer, and vigorous early growth.

AGROFERT 6 N + 10 Mg Supports leaf expansion, chlorophyll formation, and photosynthetic capacity during active growth.

AGROFERT Mn 5% + Zn 2% Corrects manganese and zinc demand to support enzyme activity and balanced vegetative development.

Crop protection

Weeds · post-emTOSILDE FORTE EC Post-emergence weed control to clear competition while the canopy is still open.

InsectsCAREZEON · CYPERTOR Applied as pest pressure builds to manage aphids and chewing pests on growing leaves and shoots.

Pre-Flowering

Before bloom

Sustain the canopy and correct micronutrients ahead of bloom, and open the disease-control window.

Nutrition

AGROFERT 6 N + 10 Mg Maintains nitrogen and magnesium supply to keep the canopy healthy and photosynthetically active.

Chelated Iron Keeps young growth green and corrects iron demand ahead of the flowering load.

Crop protection

DiseaseMELDAX · MANCOMETA · POLOGOLD Open the disease window ahead of flowering to protect against downy mildew and early leaf disease.

InsectsTARGET Manages whiteflies and sucking pests as populations begin to build before bloom.

Flowering

The yield-defining window

Position boron and calcium for a strong bloom and set, and hold disease protection at its tightest.

Nutrition

AGROFERT Boron 10% Supports pollen viability, flower formation, and fruit set during the critical flowering window.

FOLIAFERT 11-5-19 + 9% CaO + 2% MgO + TE Potassium- and calcium-rich foliar feed to support flowering, cell-wall strength, and early fruit quality.

Crop protection

DiseaseKARBISMAX · ORDES Maintained through bloom — the period when flowers and young fruit are most vulnerable to mildew.

InsectsCAREZEON · CYPERTOR Continued to protect flowers and newly set fruit from aphids and chewing pests.

Fruit Set & Early Fruiting

First fruit forming

Feed the setting fruit with potassium and calcium, sustain the canopy, and keep protection tight.

Nutrition

FOLIAFERT 11-5-19 + 9% CaO + 2% MgO + TE Potassium- and calcium-rich nutrition to support fruit set, reduce disorders, and build early fruit quality.

AGROFERT 6 N + 10 Mg Sustains the canopy and feeds the developing fruit through the early fruiting phase.

Crop protection

DiseaseMELDAX · POLOGOLD Continued to protect setting and early fruit from downy mildew and leaf disease.

InsectsTARGET · VERMACTIN Manages whiteflies, leaf miners, and mites that scar fruit and weaken the crop.

Production

Continuous harvest

Keep fruit forming with potassium, boron, and salinity management while protecting yield to harvest.

Nutrition

FOLIAFERT 11-5-19 + 9% CaO + 2% MgO + TE Sustained potassium and calcium nutrition to keep fruit setting, sizing, and holding quality through harvest.

SALINITYFIX Maintains plant performance under salinity stress during the demanding production phase.

AGROFERT Boron 10% Keeps successive flowers setting fruit through the continuous harvest period.

Crop protection

DiseaseMANCOMETA · KARBISMAX · ORDES Maintained through production to guard the canopy and fruit against downy and powdery mildew.

InsectsCAREZEON · VERMACTIN Continued against aphids, mites, and leaf miners to keep harvested fruit clean and unblemished.

Under High Production

Peak fruit load

Replenish potassium and energy under heavy fruit load to hold yield, quality, and straightness.

Nutrition

3-0-27 + Amino Acids + Organic Matter High-potassium feed with amino acids and organic matter to power peak fruiting, sustain quality, and reduce fruit deformity.

Crop protection

Disease, as neededMANCOMETA · ORDES Applied according to pressure to protect the dense canopy and maturing fruit through the heaviest harvest.

Insects, as neededVERMACTIN · CYPERTOR Applied according to pest pressure to keep peak-load fruit clean and marketable.

Know the threats

Main pests & diseases this program targets

The protection track is built around the threats that most damage open-field cucumbers — here's what to watch for in the field, and which products manage each.

Fungal disease

Downy mildew

Pseudoperonospora cubensis

Angular yellow lesions bounded by leaf veins spread fast in warm, humid weather — collapsing the canopy and cutting yield before fruit fills.

Managed with MELDAX · MANCOMETA · POLOGOLD

Fungal disease

Powdery mildew

Podosphaera xanthii

Dusty white growth coats leaves and stems, reducing photosynthesis, weakening the plant, and downgrading fruit size and quality.

Managed with KARBISMAX · ORDES

Soil-borne disease

Damping-off & seedling rot

Pythium · Rhizoctonia spp.

Soil-borne fungi rot seeds and collapse young seedlings at the soil line, thinning stands and forcing costly re-sowing.

Managed with TESTRA seed treatment

Insect · sap feeder

Aphids

Aphis gossypii

Colonies suck sap from growing tips and leaf undersides, curling foliage, fouling fruit with honeydew, and spreading virus.

Managed with CAREZEON · TARGET

Insect · sap feeder

Whiteflies

Bemisia tabaci

Clouds of tiny white flies weaken plants, deposit sticky honeydew that grows sooty mould, and transmit damaging viruses.

Managed with TARGET · CYPERTOR

Weed competition

Field weeds

Broadleaf & grass weeds

Compete with the crop for water, light, and nutrients early on, and raise humidity around the canopy that favours disease.
