Division of Crop Protection is (CPD) work with the vision of increasing the productivity and profitability of the sugar industry by controlling available pests and diseases in the plantations and avoiding introduction of new pests and diseases to the country.

Several pests and diseases have arisen in the Sri Lankan sugarcane industry over the decade and have addressed CPD successfully marking several milestones, providing new recommendations and strengthening available integrated pest ,disease and vector management packages via knowledge gathered by conducting research trials, laboratory experiments and field surveys.

To achieve this, CPD is focusing on

·         Developing IPM strategies to manage sugarcane pests

·         Developing IDM strategies to manage sugarcane diseases

·         Providing Crop Protection services to the industry

Accordingly, the division is carrying out three research projects: reinforcing an IPM package to manage sugarcane pests in Sri Lanka, reinforcing an IDM package to manage sugarcane diseases in Sri Lanka, and provision of crop protection services to farmers, industries, and other divisions in SRI upon request.

Divisional Priority Areas...

Development of AW- IPM program for Internode Borer

Development of an Area-Wide Integrated Pest Management (AW- IPM) program for Internode Borer; Chilo sacchariphagus (Lepidoptera: Crambidae)

Development of resistant varieties and development of a pull-push strategy are the key components of the AW- IPM program.

Erianthus arundinaceous can be used for the both components.

Germ plasm collection of the institute has nearly 55 different accessions of Erianthus arundinaceous.

Highly resistant accessions are used as parents for developing resistant sugarcane varieties and highly susceptible accessions are used as trap crops.

Attractant leaf volatile/s of the susceptible accessions are used to develop new pest management products by compounding with sex pheromones.

It is affected to reduce both male and female moths populations.

Our Achievements

Successful control of Sugarcane Wooly Aphid (SWA)

Threat of SWA has been addressed and managed in a successful manner during the period and SWA has become an occasional pest in the sugarcane industry.

Identifying resistant and susceptible varieties

    • SL 00 589, SL 00 601, SL 00 603, SL 00 619, SL 00 652 are zero incidence varieties
    • SL 97 1442 as highly susceptible

Introducing spraying Tobacco extraction with liquid dish wash (Tobacco extraction 100 ml + Water 400ml + 1ml of liquid dish wash) as ecofriendly alternative to manage SWA population

Identifying that the weight of the honeydew excreted as an accurate method to determine the feeding rate of woolly aphid on different sugarcane varieties

Laboratory rearing and field releasing technologies were developed. Natural enemies (Dipha aphidivora and Micromus igoratus) were introduced to the SWA infested field regularly to manage the condition successfully.

Developing IPM package for Deltocephalus menoni; vector of Sugarcane White Leaf Disease (WLD)

Identifying natural enemy spectrum and laboratory techniques

  • Ground beetle spp, Harpalus pensylvenicus (Coleoptera:Carabidae)  and Bembidion quadrimaculatum (Coleoptera:Carabidae are efficient egg predators of WLD vector
  • Identification of Earwig species (Order: Dermoptera) and Rover beetle species (Order: Coleoptera) as nymphal and adult predators of vector
  • Six predatory Coccinelid beetle spp were identified and among them Micrapis discolor, Micrapis alardi, Scymnus nubilus, Jairavio dorsialis, Propylea dissector and Pseudaspidimerus trinotatus over WLD vector and M. discolor was identifiedd as the most efficient and abundant predatory coccinellid beetle spp in sugarcane ecosystem

Identifying Saccharum spontaneum (Wild cane) and Sorghum bicolor are alternative hosts of the WLD vector and recommending to avoid them around fallowing fields and nursery areas

Identifying WLD infected plants are augmenting its vector by attracting, enhancing survival and population build-up which promotes the transmission of WLD phytoplasma itself. There recommended regular inspection and rogueing out of WLD infected clumps make a great impact on secondary transmission of WLD by vector.

Identifying resistant and susceptible varieties

Resistant varieties :SL 83 06, SL 92 5588, SLT 4921

Recommending most appropriate population techniques and durations

  • Sweep net monitoring is be : as 2000 sweeps/ ha during 6.00 to 9.00am and 4.00 to 7.00 pm ( Avoid rainy and windy days)
  • Light traps:  use white light during at 7.00 to 8.00pm in evening as 7.00 to 8.00pm (avoid the full moon period of the Luna phase)

Identifying four-month age of the sugarcane hybrids is the most vulnerable stage for vector feeding, and the three to five-month period is the susceptible period for feeding.

Identifying border treatment of Fipronil 0.3 GR (soil application of 18Kg/ha) as an effective treatment to manage the WLD vector and incidence in sugarcane plantations.

Identification of the Mustard (Brassica juncea (L.) Czern & Coss) as a repellent crop for WLD vector.

 Identifying Erianthus as effective barrier crop ( 3 rows) to minimise invasion of vector in to the sugarcane fields

Maximum flight distances of WLD vector is identified as 75 m

  • This should be minimum distance between commercial plantations and nurseries in order to minimise the secondary transmission of WLD to nurseries

Identification of behavioural characteristics of D .menoni , plant physicomorphic and leaf characteristics associated with high WLD incidence and  development of variety evaluation system for WLD vector

Managing sudden outbreak of Fall Army Warm

The Fall Army Worm (FAW), Spodoptera frugiperda (Lepidoptera: Noctuidae), is a new invasive pest of maize in Sri Lanka since October 2018.  It has damaged some sugarcane fields in all over the country and the damage severity was increasing continuously in an alarming rate. As there were no established management strategies against this new pest, studies on biology, ecology and control measures were conducted to develop a sustainable management program.

Ongoing Research Activities..

CP/1/23: Development of IPM packages to manage sugarcane pests in Sri Lanka

Damage incidences of sugarcane moth borers and spider mite have been increased in most of sugarcane plantations in Sri Lanka with high yielding sugarcane varieties. There is a requirement to reduce the crop losses due to these pests on the newly bred high yielding varieties using green management methods. Area-Wide Integrated Pest Management (AW-IPM) programs will be developed using findings of the research project.

Objectives

  •  To evaluate the effects of a new granular insecticide; Chlorantraniliprole 0.4% (w/w) G for controlling moth borers in sugarcane and to find out the effective dosage to be applied
  • To identify responsible plant volatiles for the interaction between female moth of Chilo sacchariphagus (Lepidoptera: Crambidae) and Erianthus arundinaceus   to develop new pest management products by compounding with sex pheromones
  • To identify resistant accessions of Erianthus arundinaceous which can be used as parents for developing resistant sugarcane varieties against moth borers
  • To identify suitable accessions of Erianthus arundinaceous which can be used as trap crops for developing a “Push-Pull Strategy” against moth borers
  • To evaluate non chemical strategies to manage sugarcane pest
  • To screen the newly-bred varieties for resistance/tolerance to sugarcane pests under natural conditions to avoid releasing the pest susceptible varieties for  commercial cultivations.

The IDM package is comprised introducing of resistant varieties, use of resistant inducing chemicals, chemical treatments, physical methods for disease management, studying biology of pathogens to develop management strategies.

  • To screen the newly-bred varieties for resistance/tolerance to white leaf disease (WLD), sugarcane smut disease and leaf scald disease (LSD) and to quantify the disease incidence of sugarcane varieties under natural conditions to avoid releasing the disease susceptible varieties for disease infestations to commercial cultivations.
  • To study the variation on molecular level variation of the varieties during smut infection to develop a protocol to early selection of sugarcane hybrids/varieties for sugarcane smut disease resistance
