What causes the tomato leaves and stems to turn yellow and fall off and turn brown and die?
There are many different reasons for this. It can be insect damage, the plants are too close to one another, bacterial and/or fungal damage or too much/too little water.
If there are many small dots or holes in the leaves, this is a sign of insect feeding on the leaves. A spray on poison like malathion or a sevin dusting will do the trick, just do not put poison on the blooms as you can kill your pollinators by mistake.
Plants have a natural defense to overcrowding which limits the growth or even kills it's opponents trying to exist in a confined area. Tomato leaves and stems will turn dark and this will work it's way to the main stem and kill the entire plant. If you can, use a pair of scissors and a 10% bleach to water solution in a spray bottle, spray the scissors and trim any and all discolored leaves on the entire plant. Take these clippings and throw them in the trash and not the compost pile. If you try to compost them, you can pass the disease to another or next years plants. If the entire plant is diseased, yank it up and throw the entire plant in the outgoing trash. Make sure you wash your hands with a antibacterial soap before and after you handle your tomato plants and the scissors too.
Tomato stems can withstand the bacteria in the soil but the leaves cannot. If you can, apply a mulch to keep the dirt from splashing up onto the leaves. When the plant is more developed, trim any of the lower stems closer to the ground to avoid this. Cow hay or wheat straw is a great mulch for the garden as it keeps weeds from growing and adds nitrogen to the soil as it decomposes. it can be plowed under in the spring and repeat with a fresh layer of 1-2 inches of fresh hay.
If you smoke or use tobacco products, wash your hands with an antibacterial soap before you handle your plants as the tobacco related Fusarium virus can infect and kill the tomato plant in a matter of hours. It can be introduced into your garden by another plant such as a pepper plant as well. If you can, grow your plants from seeds and not from stores that stack plants one atop others because as they water the ones on the top, diseases can be spread to the others. If you purchase plants, try to get young ones without blooms, as these are young and ones that have light green to a dark greenish blue tint as these are good signs of a healthy plant. Do not buy or handle the plants with curled leaves as this is the sign of one or more of other potential diseases. There are many other diseases to list and I will add them to this answer in the near future.
Some leave tips will turn brown, dry up and fall off. This is a sign of too much water. if the plant droops, all over, this is a sign of too little water.
