Moldy science fair project does well at local science fair...
Molds and Mildews Molds and mildews are natural decomposers. Science fair projects that examine these life forms can see how they can be controlled or used for practical applications.
Anytime you want to test how many bacteria are On Top of a surface like a desk, skin, chicken, computer keyboard, bread dough, a hard piece of chocolate, cheese, inside of an animal's cheek, etc. then use the surface experimenter kit. The kit will let you calculate how many bacteria there are per unit surface area on the object. You can also test for e-coli, however, only the microbe water kit will let you distinguish e. coli from other coliforms and bacteria.
Objectives/GoalsMy experiment was performed to find the best topical application, among Sulfur, Sodium Bicarbonate, and Trichoderma, in prevented the onset of powdery mildew on cucurbits. Methods/MaterialsI grew 40 squash plants and moved them into a greenhouse. I separated the pots into test groups, A, B, C, and D. Within each test group I labeled the plants either 1, 2, 3, or 4. The 1 pots were given no application, the 2 pots were sprayed with a sulfur/water solution, the 3 pots were sprayed with a Sodium Bicarbonate/water solution, and the 4 pots were sprayed with a Trichoderma/water solution. Then I infected all the plants by sprinkling them with powdery mildew from an infected leaf. I let it grow and measured the results. ResultsSulfur was 82% more effective in preventing the onset of powdery mildew than the control. It was 78% more effective than the Sodium Bicarbonate and 85% more effective than the Trichoderma, which is highly significant. Sodium Bicarbonate was only 4% more effective than the control and 5% more effective than Trichoderma, which is insignificant. Conclusions/DiscussionSulfur is the best topical application in preventing the onset of the powdery mildew, Sphaerotheca fuliginea, among Sulfur, Sodium Bicarbonate, and Trichoderma. 3rd party contributor
