IPM – Schedule ON MANGO

Powdery mildew (Oidium mangiferae)

Symptoms: Pathogen attacks the inflorescence, leaves, stalk of inflorescence and young fruits with white superficial powdery growth of fungus resulting in its shedding (Fig 1). When fruit grows further, epidermis of the infected fruits cracks and corky tissues are formed. IPM – Schedule

Anthracnose (Colletotrichum gloeosporioides)

Symptoms: The pathogen causes leaf spot/leaf blight, wither tip, blossom blight and fruit rots. On leaves characteristic symptoms appear as oval or irregular vinaceous brown to deep brown spots of various sizes scattered all over the leaf surface and show, shot hole’ symptom.

Die back (Lasiodiplodia theobromae)

Symptoms: It is characterized by drying back of twigs from top downwards, particularly in older trees followed by drying of leaves which gives an appearance of fire scorch.

IPM – Schedule ON Guava

Wilt: The pathogens, viz. Fusarium oxysporum f.sp. psidii, F. solani, Macrophomina phaeseoli, Rhizoctonia bataticola, Cephalosporium sp. and Gliocladium roseum are reported to cause wilting.
Anthracnose: [Gloeosporium psidii (Delacroix Sacc. = Glomerella psidii (Del.) Sheld./ Colletotrichum psidii Curzi.]
Symptoms: Fruit and leaf infection phase: Fruit and leaf infection is generally seen in rainy season crop. Pin-head spots are first seen on unripe fruits, which gradually enlarge. On ripe fruits, the infection causes softening of tissues and lesions attain a diameter of 10 to 20 mm.
Canker [ Pestalotia psidii Pat.] Symptoms: The first evidence of infection on fruit is the appearance of minute, brown or rust coloured, unbroken, circular, necrotic areas, which in advanced stage of infection; tears open the epidermis in a circinate manner. The margin of lesion is elevated and a depressed area is noticeable inside.

IPM – Schedule ON AONLA PESTS

Rust (Ravenelia emblicae Styd, Phakopsora phyllanthi Diet)

Symptoms Black pustules appear which later develop in a ring. The pustules join together and cover big area of the fruit. On leaves, pinkish brown pustules develop which may be arranged in group or scattered as infection of fruit does not go on leaves and viceversa.

Wilt / (Frost injury)

Symptoms Large number of plants shows cracking, bark splitting, defoliation and wilting symptoms. The main reason for wilting though was attributed due to frost injury, but association of Fusarium sp. was also found.

Sooty mould (Capnodium sp.)

Symptoms Sooty mould causes velvety covering of black fungal growth on the surface of leaves, twigs and flower. These are restricted only to the surface and do not penetrate into leaves .

Lichen: [Strigula elegans (Fee.) Mull. Arg.]

Lichens are found on the surface of trunk of the grown up trees. It is seen in the form of whitish, pinkish, superficial patches of different shapes on the main trunk and branches of the tree (Fig 6).

IPM – Schedule ON BANANA

 Application of 10kg Rice husk ash with 25g phosphobacteria/plant could save 20% NPK fertilizers, produce 29% more yield and generate additional net profit of Rs.39,250/ha., in Rasthali banana.

 Application of 0.5kg cement kiln flue dust per plant and 75 kg of alcohol distillery effluent/hectare could supplement 40% of recommended potassium and increase the yield by 25% in Ney Poovan banana with an additional net profit of Rs.31450/- per hectare.

 Longitudinal split banana stem traps (at the rate of 100/ha) swabbed with 20g of rice chaffy grains formulation of entomopathogenic fungus, Beauveria bassiana controls the banana stem and corm weevil infesting on banana plants.

 The technology by using 50 per cent N applied through neem cake have exhibited significant reduction in root-lesion-nematode population with increased yield in six commercial cultivars of banana.

 The technology by applying Carbofuran granules @ 40 g/plant one at planting and two applications at 3 monthly intervals after planting successfully control the P.coffeae population and increase the yield significantly in cvs. Nendran, Karpuravalli and Monthan.

IPM – Schedule FOR CITRUS PESTS

Trunk borer
Damage: Grub bores the trunk at ground level horizontally up to the pith and then tunnels vertically and again horizontally for exit. Attacked trees gradually dry up.

2.MITES (Eutetranychus orientalis Klien (Tetranychidae, Acarina)

Damage: Mite feeding causes pale stripping on the upper surface of leaves which are not seen on the lower surface. In severe infestation the stripping enlarges to dry necrotic areas.

3.Fruit fly (Dacus dorsalis Handel (Trypetidae, Diptera)

Damage: The adult fly punctures the ripening fruits by penetrating its ovipositor and lays the eggs inside. Larva on hatching feed on the pulp inside. Fungal and bacterial infection takes place through puncture hole due to which rottening of fruit occurs.
