Abstract/ Executive Summary:

Guava plants of three varieties were treated against wilting. Cultural practices when integrated with chemical measures gave good control of wilting. Manuring with N, P, K and ZnS0₄, pruning of wilted twigs, bandaging wounds with Ridomil paste and drenching of rhizosphere soils with nematicide were the best among the treatments. Continuous treatments at 15-day interval helped surviving the plants which shot new leaves and shoots after 8-9 months. Responses of Kazipeyara and Sharupkatti to the treatments were poor. Deshi guava plants were well protected with treatments.

Program Area: Pest Management

Commodity: Guava

Objectives:

To see the effects of an integrated approach against guava wilt.

Methodology:

Twenty eight plants of three guava varieties available in the kitchen gardens at the Bangladesh Agricultural University Campus, Mymensingh were used in the experiments. Guava varieties consisted of Kazipeyara, Sarupkatti and Deshi (unknown). The guava plants are those which started showing symptoms of die- back/wilting of different intensity. Among the plants, six were kazipeyara, 12 Sarupkatti and 10 Deshi varieties. The plants showing different stages of die-back/wilting were given the following treatments.

i. Cultural practices : pruning, watering the tree base, manuring

ii. Chemical control : Liming, soil application of nematicide, bactericide and fungicide, foliar spray of fungicide and bandaging wounds with fungicide paste

iii). Integrated approach: Integration of cultural practices and chemical control

Dead parts were pruned off, wounds were given fungicide paste, the foliage was sprayed with fungicide suspension and/or zinc sulphate-lime solution. Rhizosphere soils of the affected plants were amended with lime (1 kg/tree), ZnS0₄ (134-345 g/tree), fertilizers (N P K @ 100, 100 and 200g respectively per tree), nematicide (Miral 10-20g/plant) and bactericide (Sepnil, 0.3% 2 litres/tree). Weekly observations on leaf withering and twig dying and finally plant wilting were made. Together with this, observations were made for initiation of new leaves and shoots.

Achievement/Findings:

Integrated performance of the control measures was excellent. However, it took very long time to stop wilting and regeneration. Moreover, integrated approach is costly and cumbersome. It is required to be simplified.
