It is not surprising that growing tomatoes at home is a popular pastime for millions worldwide because you cannot beat the taste of a fresh, juicy tomato grown in your own garden. However, equally common are tomato plant problems, from harmful insects and diseases to inadequate care and fertilization issues. It is irrelevant whether you grow your tomatoes on your patio, in pots or in any particular direction as tomato plants can be afflicted by some or all of these of these troubles. For early signs of possible problems check the plant’s leaves as inspecting these frequently will ensure that you pick up on any changes early enough to catch the danger before it gets out of hand. If undetected, this may be impossible to cure and mean the loss of the individual plant or even the whole crop.
One of the most common problems is yellow leaves which is indicated when unfolded leaves sprout at the base of the plant working their way upwards. These symptoms could be the result of many things although it could just mean that the plant is getting old and dieing upwards from the bottom. A nitrogen deficiency in the soil could also ...
... be the cause of this. Infestations of pests, fungal or bacterial types are additional factors for this condition however these infections are usually denoted by curled, brown or deformed leaves. If the leaves are going brown or yellow further up the plant this may indicate late or even early blight so have the soil tested by a nursery to analyze if it is a nitrogen deficiency. The remedy for this would be to add a manure or compost that is well-decayed to supplement the soil as these are rich in nitrogen. A fertilizer with high nitrogen content would also suffice. If no deficiencies are found in the soil test, you should explore other avenues including blight or wilt.
Shiny, sticky, deformed leaves are particularly common tomato plant problems in younger vulnerable plants. These leaves may be yellow in appearance with a sticky, shiny matter on them. This should not be mistaken for “rolled” leaves which is perfectly normal and will not harm tomato plants. The cause of this is tiny, pear-shaped insects that gather on the top foliage or underneath the leaves, and these are called Aphids. They suck the plant’s sap damaging it and also excrete a sticky, white substance that clings to the plant’s fruit and foliage. A close inspection of the deformed leaves, as well as the normal ones, will enable you to view these bugs. Similar symptoms are also caused by spider mites and whiteflies but these insects are practically invisible. Yellow specks and fine webs on the leaves are the results of the spider mites and you will see the whiteflies fly away if you touch infected areas. Insecticidal soap and general-purpose dust for the garden will remedy these insect problems.
Brown or black spots developing on plant leaves are a symptom of early blight and will cause the leaves to drop off while the plant’s fruits may also have the appearance of sunburn. This fungus survives the winter on old vines that have been left so always clean up any old ones at the start of the season to avoid this issue. Properly spaced plants and crop rotation permit the air to circulate and are also recommended as initial steps. Prevention should be the first step to remedy this condition so rotate crops and clean up at the start of the growing seasons. Dump all stems and foliage with diseases if you see any sign of early blight and do not include this plant debris in your pile of compost. Garden dust that is for general purposes will help control the disease effectively if you catch it early enough. Leaves that appear brown, dry, and papery are a result of wet patches where water has soaked the area ultimately altering the leaves and spotting or blackening the fruit and stems in places. This late blight is the result of a fungus that favors wet weather and as its spores can spread over a vast distance it infects bigger sections. Fortunately this can be remedied similarly to early blight by control or prevention. However, if the infection is severe, it may be necessary to remove and dispose of all plants and trash completely.
If large parts of the plant’s leaves and stems suddenly wilt this may be either Fusarium Wilt,where leaves on one branch turn yellow and droop or Verticillium Wilt which initially materializes as yellowing on mature leaves between the main veins. Both of these conditions are the result of fungal infestation and this fungus is a natural manifestation within the plant and not caused by weather or lack of care. As it is inherent in the plant, this is one of the tomato plant problems for which there is no cure. Fusarium or Verticillium Wilt will both spread quickly and kill the plant. It is best to get rid of the plant swiftly without adding any of its debris to the compost pile. Limiting the risks of wilt appearing again can be done by selecting seeds or seedlings with care. While many varieties are resilient to wilt, doing this will lower the risks but there are no guarantees against reoccurrence.

DIFFERENT BLACK WORMS ON TOMATO PLANTS
There are a variety of pests that tomato plants are combating each and every day. One of them are the black worms that are also consisting of numerous kinds or types. Some of them are straight black. On the other hand, others of them are a combination of colors, but black is still the dominant color that you will see.
Enumerated here are the black worms on tomato plants that are the most common of their kind. These are the pests that gardeners and/or farmers are most likely to encounter in their tomato garden. Beware of these pests because they can definitely cause havoc to your plants or crops. Practice certain measures to prevent them in the first place. However, if they are already infecting your tomatoes, eliminate them as soon as possible.
1) Tomato Hornworm
Manduca quinquemaculata is a large, green caterpillar that gives the impression it is a worm, when referred to by its better known name – the tomato hornworm. These are very hungry bugs with a huge appetite that will strip your plant bare, leaves, green tomatoes and all. The first sign of invasion, will be small nibbles missing from the fruit and small sections from the leaves but be warned, the more they eat the bigger they grown and then more food they will require, regularly grow up to 4 inches. If you are meticulous in checking your plants daily, picking them off by hand may be sufficient to get them under control. However spotting them can be difficult, even the really big ones as they are gifted at camouflage so watch out for the signs if you cant see the worms themselves. The nibble marks are a giveaway as is frass on leaves – bug poop in other words – which resembles a cross between brown unripened blackberries and rabbit droppings.
There are also some organic methods to control the spread of the worms.
Bacillus thuringiensis or BT as it is commonly known is a natural bacteria used for centuries to control many species of moths and caterpillars. It has the added bonus of being safe for plants, animals and fish and can be purchased commercially as Dipel or Thuricide.
Pyrethrin is found in many commercial sprays and is an organic insecticide which comes from the seed pod of a flower by the same name, also known as the Dalmation chrysanthemum. In small doses it is harmful although large amounts can be toxic to both animals and humans however many commercial pest spray products contain some of this. A mixture of this and a good insecticidal soap also helps with aphids and small flies as well as the tomato hornworm.
There is a type of small wasp that only grows to around 1/4 of an inch and you can purchase their eggs at the start of the growing season. These wasps make cocoons on the worm’s backs when they hatch; those resemble tiny grains of rice and slowly eat the worm for food as they grow. This type of wasp is very common and can be found around the country so it’s possible you may be fortunate enough to have some already. If you spot a hornworm with white things attached to it, pick it off and stick it in a jar. Don’t kill it, just throw in some leaves and the pupae will turn into more wasps that will be hungry for a big juicy tomato hornworm. It is always advisable to clip the entire leaf off if you notice any damage then it is easier to tell if you are looking at a new attack or the existing one. If you keep on top of it and catch them early you’ll still have a bumper crop at summer’s end.
2) TOMATO FRUITWORMS
These pests with the scientific name Helicoverpa zea are also called as corn earworms and cotton bollworms. They have black spots or pale stripes, and they are hairy as well. At the same time, their color ranges from cream, yellow, green, reddish, or brown. Moreover, they can grow from about 1 ½ to 2 inches long.
When they are still eggs and about the size of a pinhead, they are white or cream-colored. Additionally, they are also slightly flat, spherical in shape, and will further develop brown or reddish stripes before hatching. Moreover, as they enter the larva stage, they resemble the likeness of a caterpillar. They are indeed light-colored with either brown or dark-colored head as well as dark hairs. They also feed on leaves and fruits. After this stage comes the pupa phase where they are brown in colored. They also overwinter in the soil, around in the top 2 to 3 inches

3) TOMATO PINWORMS

These pests with the scientific name Keiferia lycopersicella were first attributed as the eggplant leafminer. Then they were later redescribed as new species. Moreover, they are usually found in warm places.
When they are still eggs, these pinworms are tiny and elliptical in shape. Additionally, their color ranges from light yellow to orange. They are also deposited in small groups of around 3 to 7 on both the upper and lower surfaces of leaves. As they enter their larva stage, they are still small but are already yellowish-gray and with a brown head. Moreover, as they grow, they reach to about 1/3 inches in length. At the same time, their color changes to mottled orange-brown and then into purplish black. Next is the pupa phase where they reach to about 1/5 inches in length and turn from green to brown. Then finally comes the adult stage where they transform into small grayish moths with wings of about ½ inches in length.
4) TOMATO ARMYWORMS
These pests have achieved their name because of their nature to travel in small insect armies. Note that there are different kinds of armyworms. Moreover, each has their own way of destroying tomato plants and many other crops in general.
There are actually three kinds of armyworms: Western Yellowstriped Armyworm, Yellowstriped Armyworm, and Beet Armyworm. The Western Yellowstriped Armyworm has bright yellow stripes down its sides. At the same time, females of this kind of armyworm lay eggs covered by a cottony-type material. On the other hand, the Yellowstriped Armyworm has two large yellow stripes as well as many smaller ones. Lastly, the Beet Armyworm is pale green-colored and has light colored stripes throughout its entire body. At the same time, females of this kind of armyworm lay eggs covered by hair-like scales.
