Tamarillo best known as tree-tomatoes in Kenya is a fast-growing tree that grows up to 2-5 meters. Grafted tree tomato reaches peak production after 1-2 years while the normal ones reach after 3-6 years depending on the caltivar, and the life expectancy is about 12 years. The tree usually forms a single upright trunk with lateral branches. Grafted Tree-tomato produce 6-10 fruits per cluster. Plants can set fruit without cross-pollination, but the flowers are fragrant and attract insects. Cross-pollination seems to improve fruit

Pests That Affect Tree Tomato

The most common pests are aphids, root knot nematodes, white flies, cut worms and horn worms.

Aphids

Aphids in a tree tomato leafaphids are small sap-sucking insects. Aphids are slow moving and come in shades of green, red, brown, black and yellow. They have needle-like mouth-parts which they use to suck juices out of plants. Low to moderate aphid population levels do not usually cause significant damage and rarely kill mature plants. However, large infestations can reduce plant yields and produce sticky “honeydew,” warranting pest control.

The first step in controlling aphids is by weeding. Aphids often collect on weeds like sowthistle and mustard. Where the infestation is large you can spray effective insect sides such as Karate,  Actara or pentagon 50EC.

Root knot Nematodes

They are microscopic worms which occupy each acre of fertile earth in billions. This particular species invades various crops, causing bumps or galls that interfere with the plant’s ability to take up nutrients and to perform photosynthesis. Unfortunately, controlling nematodes is not easy.

The best control of nematodes in tree tomato fruits is by planting the grafted one as  bug weed (muthakwa) tree which is used to graft is resistance to nematodes.

White Flies

small yellow-bodied insects which have white wings, which they. They feed on the underside of tree tomato leaves, sucking out sap and weakening the plant. Affected leaves begin to yellow and die, the leaf margins usually curl inward as damage progresses.

Inspect the underside of tomato leaves for white flies. By natural control methods use a jet of water to blast white flies and wash them off your plants and leaves. Repeat this process every week to control and get rid of white flies. For effective elimination of white flies you can also use a contact insecticide namely; levo 2.4sl.

Cutworms

Cutworms chew through plant stems at the base. They primarily feed on roots and foliage of young plants, and will even cut off the plant from underneath the soil. In most cases, entire plants will be destroyed; they do a lot of damage in no time at all. Even if only the bottom of the plant is destroyed, the top will often shrivel and die.

Hand pick. Go out at night with a flashlight and gloves. Pick off the cutworms and drop into soapy water; repeating this every few nights.

Note: Apply an insecticide late in the afternoon for best control

Diseases That affect Tree Tomato (Tamarillo)

Powdery Mildew

Infection is characterized by the development of gray-white powdery growth majorly on leaves and stems, which causes them to become distorted.

The plant may eventually wilt as disease severity increases.

Spray RANSOM 600WP 15g/20l or DISCOVERY 400SC 10ml/20l or DUCASSE 250EC 20ml/20l

Blight

Initial infection occurs in older leaves with concentric dark brown spots developing on the leaves. As infection advances, infected leaves turn yellow and fall off. On stems, spots without clear contours are seen. The lesions enlarge as severity increases.

Spray EXEMPO CURVE 250SC 15ml/20l or FORTRESS GOLD 40g/20l or MEGAPRODE LOCK 525WP 15g/20l

Mosaic

This is a viral disease, and the virus is mechanically transmitted and also spread by several species of aphids in non-persistent mode.

Attacked leaves have reduced size and patches of dark-green tissue alternating with yellow-green. Generally, the plant becomes stunted and the quality of fruits is greatly reduced.

Control aphids (vectors) with KINGCODE ELITE 50EC 10ml/20l or PENTAGON 50EC 10ml/20l or PRESENTO 200SP 5g/20l
