Pannar’s maize package comprises various growth classes and includes conventional, stalk borer resistant, glyphosate tolerant and stacked gene hybrids. These hybrids are recommended for grain and silage production, as well as for maize foggage.
The formidable yellow maize package of ultra early, early, medium early and medium hybrids offers a good long-term risk-mitigating strategy.
This season, Pannar introduces three new maize hybrids with the latest PowerCore™ trait technology: PAN 3P-924PW, PAN 4P-928PW and PAN 5P-990PW. PowerCore™ technology incorporates three different Bacillus thuringiensis (Bt) -proteins, for extensive control of targeted above-ground insects. The unique combination of Bt-proteins contained in PowerCore™ technology offers improved Insect Resistant Management (IRM) against major maize pests, while its glyphosate tolerance brings a proven, convenient weed control benefit to farmers.
PAN 3P-924PW is the quickest maize hybrid with the latest PowerCore™ trait technology in the Pannar range. It boasts quick dry-down and an attractive grain type.
PAN 4P-928PW has excellent top-end yield potential and handles higher plant populations very comfortably.
PAN 5P-990PW is widely adapted with stable performance across all production areas. It has excellent early vigour and good standability.
The season’s new introductions are concluded with PAN 4A-132; an entirely new platform with strong yield stability across different yield potentials. It is highly prolific with a robust disease profile.
A new medium season platform with a robust plant-type. Good general leaf disease tolerance and wide adaption make these hybrids a valuable addition to the range. This platform is characterised by girthy ears with large blocky kernels.

Galls replace kernels of ear; galls semi-fleshy, initially firm and
silver-grey then turn black; membrane ruptures releasing brown powdery
spores.
Fungus: Ustilago zeae (Ustilago maydis)
The most characteristic symptom is the partial or complete replacement of normal floral parts by small leaves.
Fungus: Sclerophthora macrospora
Dense whitish fungal growth will be matted between the kernels and
between the ear and the husks; begin at base of ear progressing toward
the tip; small, black fungal fruiting bodies embedded in the cob tissue
and kernel bases.
Fungus: Stenocarpella maydis ( = Diplodia maydis)
Dense whitish fungal growth will be matted between the kernels and
between the ear and the husks; begin at base of ear progressing toward
the tip; small, black fungal fruiting bodies embedded in the cob tissue
and kernel bases.
Fungus: Fusarium verticilliioides = F. moniliforme (Gibberella fujikuroi)
Pink to reddish mould usually starting at the tip of the ear; mould
growth developing between husks and ears; superficial black specks
develop on the husks and ear shanks.
Fungus: Gibberella zeae (Fusarium boothii)
Floral structures partially or completely replaced by sac-like
structures containing masses of black spores; tassel proliferates to
form bizarre leafy structures; ears are smutted or aborted, small, round
to teardropshaped, with no evidence of a cob or kernels inside and lack
silks.
Fungus: Sphacelotheca reiliana
Lesions begin at edges or midrib of leaves; lesions enlarge becoming
elongate, irregular spots or streaks which are brown surrounded by a
yellow border; lesions run parallel to and are confined by the leaf
veins.
Within fields, it is likely that X. campestris pv. zeae is most
effectively disseminated by wind-driven rain or irrigation, but the
pathogen may also be disseminated by aphids, wind and plant-to-plant
contact.
Bacteria: Xanthomonas campestris pv. zeae
Pustules form on both upper and lower sides of leaf; brownish-red oblong pustules; rust band formed close to the base of leaf.
Moderate temperatures (16-25°C) and high relative humidity (>95%),
associated with mist or dew for prolonged periods, favour rust
development and spread.
Fungus: Puccinia sorghi
Brown lesions with characteristic yellow halo; develop from an oval
centre extending along the veins; black fruiting bodies develop within
the centre of the lesion.
More prevalent in warm, humid regions. Unbalanced fertility, low K,
poor drainage, mechanical and insect damage, cultivar and planting
density all influence disease severity.
Fungus: Stenocarpella macrospora = Diplodia macrospora
Small, circular to oval lesions with tan-cream centres surrounded by a
brown-purple margin and distinct yellow halo. Easily confused with
physiological changes and genetic leaf spots.
Favoured by long periods of cool (10-12°C), moist weather during the
growing season. Conidia are dispersed by wind or light rain to the
leaves of nearby young maize plants.
Fungus: Aureobasidium zeae = Kabatiella zeae
Lesions tan becoming grey as they mature; lesions typically
rectangular, limited by and running parallel to the veins; starts on
lower leaves progressing upwards.
Moderate to high temperatures and high humidity (>95%) favour
disease development. The increased adoption of reduced tillage has
increased the frequency and severity.
Fungus: Cercospora zeina
Long streaks parallel to the leaf veins developing to alternating
dark and light green variegated stripes; stunting; infected plants
yellow-green colour; deformed cobs.
MSV is only vector transmitted, primarily by Cicadulina spp.
leafhoppers of which C. mbila, is the most prevalent. MSV is not
transmitted mechanically, by pollen or via seed.
Virus: Maize streak virus
Lesions elongate becoming elliptical or cigar-shaped; grey-green
becoming tan in colour with distinct dark zones of fungal sporulation;
lesions often surrounded by pale green, water-soaked border.
NCLB is favoured by moderate temperatures between 18-27°C and
prolonged periods of leaf wetness. Conidia are produced on old residue
and are carried by the wind or rain to lower leaves of young maize
plants.
Fungus: Exserohilum turcicum (Setosphaeria turcica)
Bleached, dried, circular to elongate spots with dark brown margins,
similar to paraquat herbicide (trade name – Gramoxone) damage; pinpoint,
black fruiting bodies develop within lesions.
Lesions are usually first visible on the edges of maize fields or on
the top leaves of plants. Usually occurs towards the end of the season
as winter approaches and cold conditions prevail.
Fungus: Phaeosphaeria maydis and Phoma sorghina
Light orange to cinnamon-red, circular to oval raised pustules which are densely scattered over the upper leaf surfaces.
Favoured by warm and humid (extended dew or high humidity)
conditions, with an optimal temperature range between 24-28°C. In
temperate regions, Polysora rust occurs towards the end of the season.
Fungus: Puccinia polysora
Infected sometimes stunted; white-striped leaves; leaf chlorosis
includes base leaf; transverse margin sharply defining diseased and
healthy tissue (‘half-leaf symptom’); leaves narrower and more erect.
Oospores survive in soil and attack susceptible seedlings through
underground parts, resulting in systemic infected. Requires a saturated
atmosphere or free water and moderate temperatures of 21-25°C.
Fungus: Peronosclerospora sorghi
Black discolouration of lower stem internodes; shredding of interior;
numerous minute black specks (microsclerotia) visible on vascular
strands.
High soil temperatures (30-42°C) and low moisture or when
unfavourable environmental conditions stress the plant, especially
during postflowering period.
Fungus: Macrophomina phaseolina
Brownish pith discolouration at basal internodes; black specks
embedded in rind tissue near rotted internodes; pith disintegrates,
weakening stalk predisposing plants to lodging.
Infection usually takes place 2-3 weeks after silking under
favourable conditions. Wet, early season followed by drier conditions or
heat stress is likely to result in more widespread Diplodia Stem Rot.
Fungus: Stenocarpella maydis (= Diplodia maydis)
Sudden wilt and lodging; water-soaked, dark areas at base of stalk;
most distinctive symptom of Erwinia infection is the foul smell of
diseased, slimy plant parts.
Favoured by temperatures of 32-35°C and high relative humidity – high
rainfall and/or irrigation with surface water through overhead
sprinklers; severe when water collects in whorl and on lands subjected
to flooding.
Bacteria: Erwinia pectobacterium pv. zeae. (before Erwinia chrysanthemi pv. zeae.)
Premature senescence and lodging; whitish-pink pith discolouration
often confused with the red colour of Gibberella stalk rot; shredding of
internal stalk; black fruiting bodies absent.
F. verticilioides is most common in warm, dry areas and typically
occurs in complexes with other root and stalk rots. Infection of plants
facilitated by wounds caused by hail or insects.
Fungus: Fusarium verticilioides = F. moniliforme (Gibberella fujikuroi)
Root and stem lodging; lower internodes turn straw-coloured, internal
reddish discolouration, superficial black fruiting bodies on stalk,
often at the internodes.
Favoured by cooler, moist weather. Stalk infection usually occurs
shortly after pollination, developing at the origin of the leaf sheaths
or around the prop roots.
Fungus: Gibberella zeae (Fusarium graminearum)
The most characteristic symptom is a general light-pink superficial
discolouration of the cob as a result of the production of a red
pigment, anthocynin. The discolouration is more noticeable when the cobs
are exposed to sunlight. The discolouration is limited to the pericarp,
and does not affect meal colour after milling. The pink discolouration
may be confused with Fusarium spp.
Certain white hybrids are more prone to pinking under specific
climatic conditions. Grain may be downgraded at silos and milling
plants, having direct financial implications.
Pinking is a physiological disorder resulting from environmental
conditions, occurring sporadically. Limited information is available on
the specific temperature and humidity that predispose cobs to pinking.
Popped kernel is an irregular break in the seed coat over the kernel
crown. The kernel resembles a partially expanded popcorn kernel. The
crack in the seed exposes starch providing the ideal substrate for
secondary, saprophytic fungi e.g. Fusarium, Aspergillus and Penicillium spp.
Popping seems more prevalent in genotypes with hard, flinty kernels.
It is common in breeders’ nurseries, but rarely seen on commercial
hybrids.
Popping is believed to be the result of irregular growth, especially
since it is common in years with irregular rainfall and particularly
when conditions are very hot and dry.
Silk-cut is characterised by a horizontal crack over the face of the
kernel. The name silk-cut is probably derived from silks, which often
become embedded in ruptured areas on the tip of the kernel or
occasionally on sides of kernels between the kernel rows.
As in the case of popping, the exposed starch also gets colonised by
various fungi. This secondary colonisation enhances the kernel damage.
This phenomenon is rarely seen on commercial hybrids.
A dry period followed by wet weather, before full maturity, results
in resurgence of deposition of dry matter in the kernel – this stresses
the seed coat which cracks and breaks. Another theory is that viable
silks of unpollinated ovules push against the developing pericarp of
kernels and may also cause this rupturing.
Stresses slow silk elongation causing a delay or failure of silks to
emerge from the ear shoot. If the delay is long enough, pollen shed may
be almost or completely finished before receptive silks are available
resulting in nearly blank or totally blank ears.
Significant yield losses can be experienced. This abnormality may be
common in plants with certain genetic backgrounds, but in most
commercial maize hybrids, occurrence is triggered by environmental
factors.
Primarily caused by severe drought stress, but may also result from
heat and/or moisture stress or other stresses before or during
pollination. Excessive plant populations and nutrient deficiency may
also encourage this disorder. This phenomenon is also common in hybrids
with tight husks when cold night temperatures are followed by warm
nights during silking.
Some genes alter or limit the ability of the maize plant to produce
chlorophyll and result in albino plants or plants with white to yellow
stripes or other variegations. Some leaf spots and mosaic patterns mimic
symptoms caused by infectious diseases.
These genetic abnormalities are seen only in maize breeding
nurseries. When seen in a commercial production field, they are often
rogue plants.
Genetic disorder – genes cause abnormal morphology and colour pattern in plants.
Pre-germination of kernels occurs during the latter part of grain filling and is normally only noticed at harvesting.
Pre-germination has been observed in certain seasons in KwaZulu-Natal and Mpumalanga.
Predisposition to premature germination has been shown to be
genetically controlled and is also affected by various environmental
factors. This phenomenon normally occurs during seasons with low
sunlight hours, lots of overcast weather and low heat units. In
addition, high temperatures during the later stages of grain growth may
break embryo dormancy allowing kernels to germinate on the ear if rain
occurs around harvest time. Some ear diseases, such as Diplodia Ear Rot,
may induce pre-germination of kernels. Furthermore, molybdenum
deficiencies in the grain may also be responsible, the severity of which
is enhanced by heavy, late dressings of nitrogenous fertiliser.
