Quality is among the best of the very long distant shippers, but must be vine ripened. Goals / Objectives The focus of this research program is on quality traits, diseases, and insect pests of lettuce, spinach and melon considered by the respective industries and the scientific community to be the most critical to production. The overall goal is the development of elite germplasm and cultivars with improved quality and productivity, and new knowledge of the genetics and breeding.

Powdery mildew on melons first came into prominence in the Western US in in the Imperial Valley of California. Cantaloupes were inundated with mildew caused by what we now know is Podosphaera xanthii.

Inpowdery mildew reduced cantaloupe yield by some 30 percent, and in some succeeding years losses were as much as 50 percent. Growing Imperial 45 Cantaloupe Melon Garden Seeds.

Powdery mildew of melon (Cucumis melo) is caused by Podosphaera xanthii (syn. Sphaerotheca fuliginea), and occurs most commonly in early to mid summer on cucurbits in the Imperial Valley. xanthii is less common in watermelon than on other cucurbits.

Hi there. I am new to the whole Powdery Mildew thing and just sprayed a milk solution to my baby squash. Flowers were falling off prematurely and initially, I just cut off all of the affected leaves.

Young foliage is most susceptible to damage. Powdery mildew is a serious fungal disease that attacks a wide range of plants. While nonresistant crapemyrtle trees are especially susceptible, this disease can also attack flowers like zinnias, roses, and gerbera daisy, as well as edibles like squashes, strawberries, and tomatoes.

Powdery mildew does not discriminate and will infest any plant, given the chance. However, powdery mildew does seem to form easier on some plants than others. Plants with big leaves such as cantaloupe, cucumbers, melons, peas, pumpkins, and squash seem to contract powdery mildew.

As the name implies, powdery mildew looks like powdery splotches of white or gray that appear on the leaves and stems of plants.

Melon powdery mildew races 1 and 2 are important in the eastern U.S. (C.S. Kousik, unpublished) and Texas (K.M. Crosby, personal communication). Races 1 and 2 occur in California and Arizona, but three other races are known there as well: (Woodland-Davis, CA), 5 (Five Points, CA), and S (Imperial Valley, CA and Yuma, AZ) (McCreight, ).

Powdery Mildew Resistant Cantaloupe No. 45, seemed to be homo- zygous for resistance since continued inbreeding did not produce susceptible individuals, However, it is stated by Jagger and Scott (1) that when grown in the coastal districts of California the vines usually show some powdery mildew late in the growing season.

OK so i have a large area of my cantaloupe infected with this powdery mildew on it and i didnt know what it was since this was my first EVER attempt at growing cantaloupe and so i didnt do anything to it until here recently its taken over a lot of my plant and some of the leaves have been turning yellow and looking bad so i went to walmart and got a fungicide and sprayed it all over today, but.

The cucurbit powdery mildew responsible for powdery mildew disease in the USA is Podosphaera xanthii. Two races of P.

xanthii were known in California until when a new race, S, was observed in Imperial Valley by Jim McCreight, melon breeder with USDA–ARS, Salinas and Mike Coffey, Plant Pathologist at UC Riverside.

Initial signs of powdery mildew were not detected until May 27 on the casaba melon plants and 2 to 3 days later on cantaloupe plants. The Golden Beauty casaba melon is very susceptible to powdery mildew and was planted to serve as a nursery for production of powdery mildew fungal spores once these plants became infected.

Powdery mildew of cucurbits may occur at any time in coastal and desert production areas but is more common in fall in the San Joaquin Valley and Sacramento Valley.

The disease may be caused by one of two species of mildew fungi, although E. cichoracearum is rare. Several races of each fungus also exist. Powdery mildew refers to a group of fungal diseases that all show up as a powdery white coating on plants, especially when humidity is high.

It usually doesn't kill plants, but it can weaken them and lead to poor growth and yield. Keeping your plants healthy will help minimize damage, but sometimes you need the aid of a fungicide.

Powdery Mildew.Existing products as well as some materials under development were evaluated and compared for efficacy in management of powdery mildew on cantaloupe in a field trial conducted during the spring of at the Yuma Valley Agricultural Center.
