Recognizing Tomato Problems Recognizing Tomato Problems by S. Newman and L. Pottorff * (5/13) Quick Facts... Tomatoes are an easy and popular vegetable to grow. Despite the short growing season in many areas of Colorado, tomatoes are an easy and popular vegetable to grow. Improve garden soil by adding organic material such as compost. Failure to follow one or more of these steps can lead to pest problems. To manage pests, identify the source of the problem by assessing the symptoms. Common Tomato Problems Phosphorus deficiencies (Figure 1) occur early in the growing season when soil is still cool. Curly top virus is transmitted by the beet leafhopper. Psyllids (Figure 2) are more commonly found in eastern Colorado and are seldom a problem in western Colorado. Flea beetles (Figure 3) are small, black or brown beetles that jump when disturbed. Tomato or tobacco hornworms (Figure 4) are large, green or gray-green caterpillars with white to tan v-shaped or dashed markings on their sides. Check watering practices.
Sustainable Crop Protection - Results from the Pesticide Risk Reduction Program Biofungicides provide Post-harvest Disease Protection in Potatoes Dry rot and silver scurf are important post-harvest diseases of potatoes. Developing in storage, these diseases can infect up to 60% of stored tubers, leading to significant economic losses. (all photos courtesy K. Dry Rot, caused by the soil borne fungus Fusarium sambucinum, enters the tuber at wounded or bruised sites caused by planting, harvesting, grading or transport. To address these concerns, the biocontrol product Bio-Save® (10LP and 11LP) was evaluated for control of dry rot and silver scurf of potatoes. Efficacy of Bio-Save, Mertect, and a combination of both against Helminthosporium solani strains The efficacy of Bio-Save® against F. sambucinum and H. solani isolates, representing New Brunswick, Prince Edward Island and Alberta strains, was tested in the lab and in storage trials.

Introduction to Cellular Respiration. Introduction: Once the energy that was in sunlight is transformed into chemical energy, often by photosynthesis, the organism has to now convert the chemical energy into a usable form. It may seem a bit odd for there still to be more steps. After all, when you eat a candy bar isn't the sugar in the candy bar "burnt" by the body to provide energy? Well the answer is yes and no. First of all when we burn something normally in the air we combine that substance with oxygen releasing energy from the substance. What goes on in living things is not really like burning because the molecules from which we harvest energy give up their energy in a controlled fashion rather than all at once as what happens in a fire. The Point of Cellular Respiration The point of cellular respiration is to harvest electrons from organic compounds such as glucose and use that energy to make a molecule called ATP. More about the role of of ATP in metabolism is here. Aerobic Respiration. Stages in Aerobic Respiration:
Mini-Lessons In general, mini-lessons should last approximately 10-15 minutes. “Maxi-Lessons”, such as lessons that introduce a new skill or multiple techniques, may require more time. However, during a longer lesson, there should be significant time for students to practice with the skill, not just listen to the teacher. A typical mini-lesson will include: 1. A direct statement about the concept or skill to be taught. 2. 3. 4. 5. 6. 7.

Understanding disease resistance codes for tomatoes Tomato disease resistance codes are listed on tomato seed packets or on tomato seedling labels. They appear in capital letters. Here’s the dirt: many tomato varieties are bred specifically to resist particular diseases. This is helpful information if you want to grow healthy plants! When you see what looks like a confusing group of letters on plant or seed packets, never fear. Instead, you’re looking at disease resistance codes, which are special gardening lingo for “here are some really good characteristics of this plant.” Here’s how to decipher disease resistance codes. Tomato Disease Resistance Codes V Verticillium WiltF Fusarium WiltFF Fusarium, races 1 and 2FFF Fusarium, races 1, 2, and 3N NematodesA AlternariaT Tobacco Mosaic VirusSt Stemphylium (Gray Leaf Spot)TSWV Tomato Spotted Wilt Virus An example may make things clearer For instance, when you see a plant that has disease resistance codes VFN after its name, then it’s resistant to verticillium wilt, fusarium wilt, and nematodes.
Potato Research, Volume 27, Number 2 Seed tubers with severe (80–100% of surface affected) or slight (less than 20% of surface affected) silver scurf were selected from commercial stocks and planted at Rothamsted in 1979–81. Severely affected seed lost more weight (13%) than slightly affected seed (8%) during storage on trays, and produced more but smaller sprouts. Ground cover, leaf area and tuber yields were decreased by severe infection for up to 7 weeks after planting but thereafter effects of seed infection were non-significant. In two years, tubers produced from seed with severe silver scurf had less infection than those from slightly affected seed, but in 1980 most disease developed on tubers from seed with severe infection. In Rothamsted wurden in den drei Jahren zwischen 1979 und 1981 Pflanzkartoffeln mit starkem (80–100% Oberflächenbefall) oder schwachem (Weniger als 20%) Silberschorfbesatz gepflanzt, die aus Konsumanbau stammten. 1979 wurden auch Knollen mit mittlerem Befall (40–60%) einbezogen.
Prokaryotic and Eukaryotic Cells Part of our definition/description of what it means to be a living thing on Earth includes the assertion that living things are made of cells and cell products. In other words, we consider the cell to be a pretty fundamental structural aspect of life. Cells in our world come in two basic types, prokaryotic and eukaryotic. "Karyose" comes from a Greek word which means "kernel," as in a kernel of grain. Here's a simple visual comparison between a prokaryotic cell and a eukaryotic cell: This particular eukaryotic cell happens to be an animal cell, but the cells of plants, fungi and protists are also eukaryotic. Despite their apparent differences, these two cell types have a lot in common. Some things which seem to be differences aren't. Despite all of these similarities, the differences are also clear. If we take a closer look at the comparison of these cells, we see the following differences: Eukaryotic cells have a true nucleus, bound by a double membrane.
