57. • Production:- • The production of guava in high density planting (1.5 x 3 m.) is 26 tonnes ha-I in the third year. The yield goes up to 47 tonnes ha-I in the fifth and 55 tonnes ha-I in the seventh year of growth. • In the density of 6.0 x 6.0m, the yield is 6 tonnes ha-I Guava Wilt. Wilt in Guava tree is caused by a fungus Fusarium solani or Cephalosporium sp. or Rhizoctonia sp. The symptoms appear on the infected trees many months after roots have been attacked by the fungi. Sparse foliage, yellowing of Guava plant leaves, and tree wilting are the symptoms. Before a wilting tree can flower profusely and set.

Guava wilt. Disease symptoms: First symptoms start with the onset of monsoon. Appearance of light yellow foliage with loss of turgidity and epinasty. Plants, at a later stage, show unthriftyness. Subsequently, premature shedding and defoliation. Some of the twigs become bare and fail to bring forth new leaves or flowers and eventually dry up Rootstocks for guava can either be grown from open pollinated seeds or clonally propagated. Edward and Shankar (1964) found a compatible wilt resistant Chinese guava rootstock (Psidium friedrichsthalianum) and had small bushes.Shankar (1967) reported that P. molle, P. guineense, P. cattleianum, and Phillippines guava were found suitable as.

Guava plants are attacked by wilt, which alone causes heavy losses. It is very difficult to find out an orchard of guava more than 30 years in age because moat of its plants die at about 20 years of age due to wilt. Various fungi causing wilt are Fusarium roseum oxysporum f. psidii, F. solani, Hacrophomina phaseolina and Gliocladium. Guava wilt disease caused by a soilborne fungus F. oxysporum f. sp. psidii is emanating as a serious threat to guava growers throughout the entire globe. To control this disease, Mishra et al.

The lettuce root aphid is a soil dweller that attacks lettuce roots in spring and summer, causing lettuce plants to wilt and occasionally die. In fall, this species often moves to poplar trees, where it overwinters in the egg stage and produces leaf galls in spring It is 1/8 in (3 mm) thick, adhering to a 1/4 in (6 mm) layer of white pith. Within is a cavity more or less filled with an aromatic mass of double-walled, membranous sacs filled with orange-colored, pulpy juice and as many as 250 small, hard, dark-brown or black, pitted seeds. The flavor is appealing, musky, guava-like, subacid to acid Young leaves wilt without yellowing. Copper compounds are often used in the orchard in organically approved sprays (and in conventional sprays) that are used to control fungal disease. It is immobile in the soil, so if copper sprays have been used in the past, it is worth doing a soil test to determine the amount of copper present

Bacterial wilt Plant Disease. Cause: This kind of common plant disease is caused by cool and wet weather. Leaf Disease Identification Farmers should look up for large, yellow spots on leaves. Those yellow spots often change to a brown color. Treatment The appropriate corrective action that should be taken is removal of infected plants Fruits Ripening Gas - Ethylene The natural question is what is ethylene gas, how it is used and is it safe for humans. Ethylene is a hydrocarbon gas (C 2 H 4, molecular weight 28.05), flammable, odorless, harmless and tasteless [2].It is a type of plant hormone, known as senescence hormone released by fruits and vegetables The coconut palm, Cocos nucifera, is an erect palm in the family Arecaceae which is grown its fruits, used primarily for the extraction of coconut oil for use in cooking.

ADVERTISEMENTS: In this article we will discuss about the classification of plant diseases. (i) Diseases classified in relation to their occurrence: Study of plant dis­eases in relation to their occurrence (interaction of populations of plants, pathogens and environment) is known as epidemiology. There may be infectious disease and contagious disease. A disease which spreads slowly [ Tomato Plants Wilt Due to Under Watering. The most common and easily fixed reason for wilting tomato plants is simply a lack of water. Make sure that you are properly watering your tomato plants. Tomatoes need at least 2 inches (5 cm.) of water a week, provided either through rainfall or manual watering Papaya leaf curl disease. Disease symptoms. Curling, crinkling and distortion of leaves, reduction of leaf lamina, rolling of leaf margins inward and downward, thickening of veins. Leaves become leathery, brittle and distorted. Plants stunted.Affected plants does not produce flowers and fruits Basic requirements Rice is mainly grown in warmer regions as the plants will not grow at temperatures below 10°C. Rice is considered to be a semi-aquatic annual grass and is commonly grown in paddies in wetlands or under shallow water. Several new methods of propagating rice have been developed which allow rice to be cultivated in less conventional areas e.g. drought resistant varieties are. Irrigation Guidance for Cultivation of Coriander. First irrigation should be given immediately after sowing. Irrigation requirement is depending upon the parameters such as climate, soil moisture level, and the variety used. Standard irrigation schedule is 5-6 irrigations 30-35, 60-70, 80-90, 100-105 and 110-150 days after sowing

Disease symptoms. The disease causes serious losses to young shoots, flowers and fruits It is also affects fruits during storage. The disease produces leaf spot, blossom blight, wither tip, twig blight and fruit rot symptoms. Tender shoots and foliage are easily affected which ultimately cause die back‟ of young branches After it has been growing for six to eight months, leave one sucker (small shoot at the base of the stem). This plant will replace the main stem in the next growing season. After the fruit is removed, cut the main stem down to 2.5 feet. Remove the rest of the stem in a few weeks, leaving the replacement sucker intact Downy mildew (Plasmopara viticola) affects many plants and appears as yellow to white patches on the upper surfaces of older leaves.On the undersides, these areas are covered with white to grayish, cotton-like fungi. These downy masses are most often noticed after rain or heavy dew and disappear soon after sunny weather resumes Guava Weevil: Conotrachelus dimidiatus Champion. The guava weevil (Fig. 16.5, center) is one of the principal pests of guavas in Mexico, Honduras, and Guatemala. Guava fruits are damaged when females oviposit into the mesocarp and larvae penetrate into the interior of the fruit, blackening the pulp and seeds and causing fermentation and fruit. The best control of downy mildew is to make sure that your plants do not get it in the first place. Since downy mildew needs water to survive, the very best thing you can do to prevent downy mildew is to water your plants from below. Water that sits on the leaves of the plant gives the downy mildew a way to infect and spread on the plant

New transplants require tender loving care. Be sure to provide plenty of water. If you transplant during a hot period, plants will most likely experience some shock and may wilt. If you can, protect transplants from the hot sun while they establish. A 4 inch (10 cm.) layer of mulch will help to retain moisture Chlorine. You may not realise it but chlorine is classed as a plant micronutrient meaning that it is essential for the proper growth of plants. It is important to note though, that it is the ion (Cl ‑) rather than the gas (Cl 2) that is used by plants.In particular, chlorine is important for plant photosynthesis as it is involved in the opening and closing of stomata (pores in leaves that.

Root-knot nematode symptoms on plant roots are dramatic. As a result of nematode feeding, large galls or knots can form throughout the root system of infected plants.
