Written by Dr. Shaun Murphy

Here is about some disease in tomatoes plants like pests,spidermite, tomato hornworm etc. Also we will look at HOW TO FIX THESE ISSUES even you are growing them at home.

Welcome to farmingocean. Lets talk about some disease of tomato & tricks to fix them.

Homegrown tomatoes are something else – beautiful rich fruits with the most divine aroma! But growing tomatoes successfully depends on avoiding some of the common pitfalls that can trip you up along the way.

Knowing exactly what to expect and what to do about it will greatly improve your chances of a terrific crop of tomatoes. In this blog, we’ll look at how to troubleshoot some of the most common tomato problems.

1.Pests(bugs on tomato)

Aphids and whiteflies are regular visitors from early summer. They often congregate in large numbers, sucking sap from your plants and leaving their sticky excrement or ‘honeydew’ on the  foliage. Some types also transmit plant diseases.

Small infestations can simply be blasted off with a jet of water, or try spraying plants with a solution of soapy water, taking care to reach leaf undersides. To minimize potential problems, attract pest predators such as ladybugs and hoverflies by planting flowers close by – marigolds are a great choice. You can even buy these predators ready to introduce into enclosed environments such as a greenhouse.

2.Spider mite

Warm dry, conditions are perfect for spider mites which, like aphids and whitefly,can quickly weaken plants. Look out for their faint webbing. Peer closer and you may be able to seethe tiny, usually red, mites.

Spider mites love drought-stressed plants, so don’t let your tomatoes dry out. If spider mites do attack, spray the foliage with a fine mist of water, insuring you reach all parts of the plant, then cover the plant with a row cover for a few days to create the shady,humid conditions that repel the mites.

3.Tomato hornworm

Many parts of the world are prone to tomato hornworm, a caterpillar that chews holes into tomatoes. Check plants regularly for any signs of damage, and remove and destroy any caterpillars you find.

Cocoons, this is great news. They belong to braconid wasps, whichfeed on hornworms to bring them under control.

Late blight strikes during spells of warm, wet weather. Foliage, and then the fruits, become covered in brown blotches. Eventually the plant simply wilts and collapses. Late blight also affects potatoes,which are related to tomatoes.

how to fix it

Blight is rare on indoor tomatoes, so grow plants under cover if it’s been a problem in the past. Keep the foliage dry by watering at the base of plants, and remove and destroy any infected plants as soon as you spot the first signs of blight. You can also grow varieties described as blight resistant.

5.Blossom end rot

Blossom end rot is a disease caused by dry conditions at the root zone and a shortage of calcium. Fruits form sunken black patches at the blossom end of the fruit.

how to fix it

Insure your tomatoes have enough water at all times, and feed them regularly with a liquid tomato fertilizer. This is the best way to guarantee your plants are getting all of the minerals and nutrients they need for healthy growth. Pay particular attention to plants in confined spaces such as pots or growing bags.

6.Split fruits

Irregular watering often leads to split fruits,when a sudden rush of water causes the fruits to swell quicker than the skin surrounding them.

how to fix it

Instead of leaving soil to completely dry out between each watering, aim for consistent soil moisture. Water regularly, and mulch tomatoes with plenty of organic matter to keep roots cool and moist.

7.Mineral deficiency

Mineral deficiencies usually show up in the leaves first. Magnesium deficiency such as this is the most common form, and often arises as a result of high potassium levels.

how to fix it

To correct the deficiency,spray a solution of epsom salts directly onto the foliage then switch to a tomato feedthat contains a high proportion of magnesium.

8.Wilted plants

Plants can wilt when the soil is either too wet or too dry. Too wet and the roots literally drown, while very dry soil won’t supply plants with all the moisture they need.

how to fix it

Pay close attention to watering. Containers of tomatoes should have good-sized drainage holes at the base so that excess water can drain out. Raise containers up onto pot feet if water doesn’t drain away easily. In all cases,water generously when it’s dry or set up an irrigation system if you can’t be there to water. Later on in the season, mature plants with lots of foliage may need watering twice a day.

9.Poor fruit set

Poor fruit set – when flowers fail to produce fruits – is a very common problem. A lack of bees, excess heat, very dry or humid air, and poor nutrition are all possible causes.

how to fix it

Make sure pollinating insects such as bees can reach plants growing in greenhouses and tunnels. Improve pollination by simply twanging or tapping on supports to dislodge the pollen, or gently twiddle the flowers between your fingers. Provide as much ventilation as possible in hot weather.

If your climate’s also very dry,raise the humidity around plants with regular watering and make sure to feed your plants regularly with either an off-the-shelf tomato feed or a homemade high-potassium liquid fertilizer such as comfrey tea.

Don’t be put off by all these potential problems. So long as you know what you’re looking at, and react quickly, your tomatoes are very likely to recover. Now, please do let us know about any other tomato problems you’ve experienced in the comments section below, and how you got around them.
