We want to advise you that the bacterial fruit blotch disease of watermelons has again appeared in water- PHORQ À HOGV LQ PDQ\ ZDWHUPHORQ SURGXFLQJ DUHDV This disease has been periodically reported since its initial detection in 1989. Losses from this bacterial disease have ranged from minor to as high as 100% of the marketable fruits.
The causal agent of the fruit blotch disease appears to be closely related to Acidovorax avenae subsp. citrulli (synonym: Pseudomonas pseudoalcaligenes subsp. citrulli). The pathogen could be seed-borne from the original seed lot, or result from other host infection. The disease has attacked many varieties of watermel- on from different seed producers.
Although new testing procedures are currently un- der development, it is impossible to conduct any test procedures that will give 100% reliable results with UHJDUG WR WKH LGHQWLÀ FDWLRQ RI DQ\ VHHG ERUQH ZDWHU melon fruit blotch infections. Work is being done by public and private researchers, seed companies and JURZHUV WR GHWHUPLQH LPSURYHG LGHQWLÀ FDWLRQ DQG control measures and to develop statistically reliable testing procedures.
Work is also being done to determine if different va- rieties of watermelon, both diploid and triploid, have any level of resistance or tolerance to this disease. No YDULHWLHV WR GDWH KDYH EHHQ LGHQWLÀ HG DV KDYLQJ DQ\ VLJQLÀ FDQW OHYHO RI UHVLVWDQFH
The symptoms on young seedlings appear as dark water-soaked lesions on the lower surfaces of the cot- yledons or the true leaves. These initial water-soaked lesions later turn necrotic and may also have chlorotic halos surrounding the dead tissues. The lesions will also often appear on the hypocotyls of young seed- lings, resulting in the wilting and death of these young plants. The most dramatic and destructive phases of this disease are the fruit infections that occur much later in the growing cycle. The lesions on the top sur- face of the fruits appear as small, water-soaked areas, which under the right conditions of high temperature and humidity, enlarge rapidly to cover most of the sur- IDFH RI WKH IUXLWV )UXLW GHFD\ RIWHQ IROORZV 7KLV ODWHU FRQGLWLRQ RI WKH GLVHDVH F\FOH FRXOG OHDG WR VLJQLÀ FDQW economical losses to the grower.
In cases where the pathogen is carried in the seed, the typical lesions described above will appear on the young seedlings within 7 days after seedling emer- gence. If no symptoms are observed on the young seedlings within three weeks after emergence, it is unlikely that the bacterium is carried on the seed and that any subsequent infection is most likely from other sources. It is imperative that each grower inspect the young plants during this early stage, in order to deter- mine the presence or absence of these symptoms and to mitigate any potential economical losses.
Caution: Symptoms that appear on plants in the early stages of growth, and especially those symptoms caused by secondary infections, may not be evident on new foliar parts as the plants develop. The patho- gen, however, may still be alive in infected tissues, and may infect the fruits if favorable conditions of temperature and humidity prevail. Do not retain any plants that show any symptoms at any time.

And cut fruit displayed in shrink wrap is a sure seller.
Sometimes incorrectly referred to as "seedless", triploids are sterile hybrids which, because of their genetic makeup, characteristically produce fruit with few or no true seeds. Sometimes cultural practices or weather conditions may result in fruit with some vestigial seeds or empty white seed coats. Because of this, triploid F1
watermelons are not
guaranteed to produce seedless fruit. A special note to growers of triploid F1
Please follow careful practices to grow triploid F1
watermelons: wa-
termelons successfully. We supply detailed growing instructions with your seed. For best results, we sug- gest starting seed in the greenhouse in peat pellets (on page 90) 3 weeks before outdoor planting time. Because of their genetic makeup, triploid F1
