As a result, the roots fail to keep up with the water and nutrition demand from the leaves. Other factors that may result in physiological leaf roll include transplant shock, root injury, over pruning, phosphate deficiency and high nitrogen intake.

Symptoms: Physiological leaf roll can be identified by its characteristics whereby the lower and older leaves will have an upward curl followed by an inward curl towards the mid-vein. This condition then spreads gradually towards the upper shoots, but the leaves still maintain their natural green color. Tomato plants are highly sensitive to hormone-based herbicides, insecticides, and fungicides.

It's also important to remember that most of these chemicals can be transferred from nearby farms by strong winds. Symptoms: Standard symptoms of chemical injury include downward rolling leaves which can also be twisted, split stems with yellowed or chlorotic and malformed fruits.

Extreme Weather Conditions Causes: High winds especially when accompanied by low humidity and dusty conditions will automatically trigger leaf curl. Tomato plants rely on leaf curl as a self defense response to extreme weather conditions. The same response will kick in if you fail to water your plants frequently. Tomatoes are also sensitive to excess moisture such as during rainy weather accompanied by cold temperatures.

Symptoms: In such conditions, the leaves will generally turn leathery, thicken and curl inwards. This can be used to differentiate weather-related leaf curl from other conditions.

These are spread via human contact especially if you have been in contact with tobacco and most notably by aphids and whiteflies. Symptoms: Leaf curl as a result of these viruses is usually accompanied by other identifying symptoms such as yellowing leaves, stunted growth, purple veins on the leaf underside and internal browning of fruits.

Damage may start moderately then quickly begin to affect new growth. Damage to tomato and other vegetable plants may have one or a combination of causes Figs. There are five primary reasons that tomato leaves twist or curl:. High winds, blowing dust and low humidity can damage the leaves and stems on tomato plants.

Injury is similar and is often confused with drift damage from phenoxy-type herbicides Fig. Heat and low moisture can cause the edges of the tomato leaves to die back, then twist and curl. Hot dry weather may also cause a symptom called physiological leaf roll. This is a self defense response, where leaves and leaflets curl slightly to prevent further water loss Fig. Mild leaf roll generally does not lower yields or quality, though severe symptoms may cause flowers to drop and fewer fruit to set.

These symptoms may look like damage from other causes, but if wind damage is the only problem, plant health will generally normalize once weather conditions improve. Crops and pastures are often treated with herbicides to prevent or eliminate weeds, and drifting spray can damage tomato plants.

Up to 84 percent of the cotton acreage in Texas is sprayed with broad-spectrum herbicides. They are also used on cereal and grain crops.

The problem is that wind speeds as low as 5 mph can move these herbicides up to a mile. Many home gardens are close enough to cotton and corn fields for drifting 2,4-D, dicamba, or other hormone-type herbicides to cause serious damage. Tomato plants are extremely sensitive to these herbicides: they can be injured by concentrations as low as 0. If only a little of the herbicide reaches the tomato plants, they can recover, but yield will definitely suffer Fig.

In addition to commercial applications, herbicides from home gardeners or their neighbors can drift onto sensitive tomatoes or other vegetables. Weed killers for lawns and landscapes often contain broad-spectrum herbicides such as glyphosate and the growth regulators such as 2,4-D and dicamba. Tomatoes are very sensitive to these herbicides even when applied at extremely low rates.

Though the plants may look healthy, drift from these products can reduce the number and the quality of the fruit. There is no remedy for leaves that are already injured by 2,4-D. If new growth continues to show injury symptoms, harvest any salvageable fruits and pull up the plants.

If new shoot growth is normal, and there is still at least 4 to 6 weeks left in the growing season, the plants may be able to outgrow the injury. New buds and leaves should begin growing within about a week. If not, pull the affected plants and replant. Vegetables can be damaged by herbicides left in mulch or compost made with hay or manure from fields that have been sprayed with Grazon, GrazonNext, or GrazonNext HL.

The active ingredient in these products is aminopyralid which persists for 18 months on treated hay and hay products. It also persists in the manure of animals that eat Grazon-treated hay. Grazon products are commonly used in pastures because they kill about difficult broadleaf weeds.

Remedies for Leaf Curl in Tomato Plants

The GrazonNext label states that any plant matter collected from fields sprayed with aminopyralid may not be used in compost or where vegetables are to be grown Fig.

Anyone who sells hay, silage, haylage, green chop, or bedding material that was treated with aminopyralid, is responsible for alerting the buyer that it was treated and must not to be used in composting or were vegetables are grown.

As a result, plants lose water from their leaves at a faster rate on hot, dry days.

To prevent this, tomato plants will curl up their leaves on dry days. Dry days are often sunny days, so this strategy also reduces the surface area of the plant exposed to the sun. This reduces heat stress on the plant. Combined with dry air, a strong wind can make physiological leaf roll worse.

When the wind is blowing, plants lose water through transpiration even faster. A tomato plant will curl its leaves to prevent this from happening.

Ozkan is a mountain guide in Turkey so he is very aware of the preparation needed to enable a smooth trip of the sort we experienced. We both felt the service we received was outstanding. We did not use the GPS that came with the hire car because with the quality of the maps and information provided there was no need.

All the places we stayed were very welcoming, very clean and the breakfasts, especially the bread, were often outstanding. We were also very lucky with the weather but doubtless that is beyond your control. We would just like to say thank you for your superb organisation, excellent provision of information and selection of places to stay that helped us to have an outstanding holiday. We were very impressed with all the areas of Norway that we saw. Everything was clean, convenient and friendly.

Really enjoyed the historic hotels. Easy to work with Bjarni. He made excellent choices for our hotels. Very impressed with the arrangements made - easy to follow independently. Pleased with location and standard of hotels. Delighted with the service you provided from the first email correspondence with Irja, right through to being dropped off at the airport at the end of the tour.

I have just completed a two week drive around Iceland. The bookings were all handled by Nordic Visitor Centre. I stayed at farmhouse hotels for most of the trip.

I couldn't speak more highly of the whole experience. There was a volcano eruption while I was touring and the NVC contacted me before the eruption to warn me about it and afterwards to see where I was.

The whole service was excellent and I will certainly use NVC if I can get back to Iceland.
