Guava trees bear more fruits in certain times of the year, a light crop in the spring and a heavier one in the fall. Guava leaves contain tannins as well as β-sitosterol, flavonoids, triterpenoids, volatile oil. Negligible flower drop has been observed. About 7 cm. The program should ensure the vigor of trees with sustained capacity to produce quality fruits. The ripe fruit is popular as dessert. Cultural practices such as increased plant to plant spacing to promote air circulation, avoidance of overhead irrigation and irrigation regimens that extend leaf wetness periods, good sanitation practices (removal of infected plant debris, management of weeds that may be potential hosts, standing water, etc.) Arka Mridula trees. Inst. Meanwhile, thousands of miles away in Australia, scientists rush to save a beloved native guava, decimated in just ten years by the arrival of a fungus. A guide to Guava plant diseases and pests.. The most effective management combinations, next to carbofuran 10G, in suppressing the nematode densities in the rhizosphere of guava trees were P. lilacinum + P. penetrans + urea 46%, P. lilacinum + P. penetrans + chicken manure, and T. harzianum + P. penetrans + chicken manure (66.54–69.22% nematode reductions). NATURAL ENEMIES None have been reported from Fiji, but it is likely that minute species of wasp parasitise the eggs or larvae of the guava bud moth.

Integrated management of plant-parasitic nematodes on guava and fig trees under tropical field conditions Ahmed A. M. Dawabah1*, Fahad A. Al-Yahya2 and Hamzeh A. Lafi2 Abstract Two field experiments were carried out to study the efficacy of different biological control agents in controlling certain plant-parasitic nematode species including Meloidogyne javanica,Tylenchorhynchus … J Agri and Ecol. 5: 73-79. Young fruits drop due to competition, however 3-4 fruits can mature at one point. Early harvesting: The trunk may be branched at the base and the branches droop low to the ground. Edward (1960a) suggested that while transplanting, roots of plants should not be severely damaged. Bearing trees , once affected, slowly die away. As indicated in various experiments; ... For maintenance of fresh culture, infested fruits of guava were collected from guava orchard at farmer’s field. and proper nutrient management plans to maintain vigorous plants. Guava, Psidium guajava, is an evergreen shrub or small tree in the family Myrtaceae grown for its edible fruits. The solution of pheromone was formulated with ethanol, methyl eugenol and malathion (6:4:1). Mushroom … But under high density planting system, light and other microclimatic conditions are important aspects which directly or indirectly affect the vegetative growth, yield and quality of guava fruits. They are one of 150 species of Psidium, of which most are fruit bearing.Hardy the guava may be, but they do have their share of guava pest problems, most of which can be dealt with using natural pest control methods for guava trees. Effect of pruning on growth yield and quality of guava (Psidium guajava L.) var. The possible and useful techniques have been added in this article to devise management tactics for the spectacular success of this serious and noxious pest of guava. An evaluation of cultural practices of orchard management was studied on 16-yr-old healthy and productive guava cv. The yield of a plant depends on its age, cropping pattern and the cultural practices. The standard plant spacing is 6 m. x … Guava has a slender trunk with smooth green to red-brown bark. The plant possesses oval or elliptical leaves which are smooth on the upper surface and hairy on the lower surface. Cultural control Diaphorina citri Huanglongbing Interplanting Psidium guajava abstract No sustainable management practices have been established yet for citrus greening disease (CG). 4. 1: 85-90. Disease management through cultural practices: Mathur (1956) advocated that wilt could be controlled by proper sanitation in the orchard. Nation Building Proposed Topic: “The management of Guava farming to ... memories about cultural operations of guava cultivation. 5. A farmer’s participatory approach was used to popularize the application of pheromone traps in guava field as an IPM treatment. Prog Horti. Fruit fly management in Guava orchards using Pheromone traps. Guava bears flowers solitary or in cymes of to 5 flowers in the axil of the leaf on the current growth. This system is called silvopastoral. Canopy management in Guava For managing the canopies of the trees under high density planting approaches like pruning and use of growth retardants singly or in combinations may be exploited. etc., are some other important diseases. The Guava plants are usually planted at a distance of 5-8 m. The exact Guava planting distance is decided according to variety, soil fertility, and availability of irrigation facilities. Fortunately most species have natural enemies that keep their populations below damaging levels in outdoor systems such as landscapes and gardens. Cultural Control and Sanitary Methods Collect and destroy affected fruit to reduce the inoculum. In the HRS there are two cultural management systems of guava production: the traditional system, in units of less than one hectare, with trees without density of sowing, without pruning of formation or fructification, in a state close to the sylvan. Show: Recommended. A 10 year-old plant yields about 100kg of fruits every year. Because of their perishable nature, guava as disposed of immediately after harvesting in the local market and a very small quantity is sent to distant markets. Guava fruit harvest peaks can deviate with prevailing weather conditions and cultural practices because flowers are produced on new growth. Mealybugs are very difficult to manage with insecticides.

Agricultural consultation was limited to the Rural Agricultural Department Agency (RADA) in Mandeville and the Ebony Park Academy. In addition, the formulation of a fertilizer management program is important in growing durian. Management. Correspondent combinations in the rhizosphere of fig trees … Irrigation (Singh et al., 1997), fertilization (Shigeura and Bullock, 1976), defoliation and pruning (Singh et al., 1996, Shigeura and Bullock, 1976, Shatat, 1993) can be used to stimulate new growth and influence fruiting in guava. MANAGEMENT. Cancker, cercospora leaf spot, seedling blight. The culture was maintained at 25±2°C in BOD incubator. Considering a planting density of 150 trees per acre for pink guava and yield from a mature tree of 65 pounds per year, average pink guava yield per acre is 9,750 pounds. Crop cycling depends on the natural flowering and fruiting tendencies of the guava tree. All Time. Res. Management. culture was identified by Fungi Identification Research Dept, Plant Pathol. The attractant methyl eugenol was used by the survey team in the northern part of Vietnam, but failed to trap any fruitfly.Methyl eugenol is widely used in fruitfly control programs in Thailand, for example in guava plantations.
