Apple Diseases Threaten Crops in Himachal, Read How to Deal With Them

saving apple crops from diseases

Shimla-Apple scab and other foliar diseases threaten the apple crop in Himachal Pradesh and farmers in the apple growing areas have been advised to be vigilant. The Department of Plant Pathology of Dr YS Parmar University of Horticulture and  Forestry(UHF), Nauni, has issued an advisory for the management of Apple scab in Himachal.

Due to the rains in the first fortnight of May, high humidity conditions are prevailing in the state which makes it congenial for the spread of apple scab and other foliar diseases, the advisory said. The Department had proposed to organize 24 group meetings of farmers in the apple-growing districts of the state to create awareness about the disease management approaches to deal with these diseases in apple crops.

Due to the imposition of the Corona curfew, the process was halted, but the University has created two Whatsapp Groups – one of the representative farmers and another of Horticulture Extension Officers from the different districts- to communicate the advisory for the farmers to be followed during May-June, 2021. As the apple fruit is in the  development stage, the farmers need to adopt the following recommendations.

Spray Schedule for Apple Crops Recommended for the Year 2021:

When the fruit is of walnut-size:

  • The sprays of mancozeb @ 0.3% (600gm / 200L water) or propineb @ 0.3% (600gm / 200L water) or dodine @ 0.075% (150gm / 200L water) are recommended for the management of apple scab.
  • Metiram 55% + pyraclostrobin 5% WG @ 0.1% (200gm / 200L water) or tebuconazole 8% + captan 32% SC@ 0.25% (500ml / 200L water) or fluxapyroxad 250g/l + pyraclostrobin 250g/l 500SC @ 0.01% (20ml / 200L water) are recommended for the management of premature leaf fall and Alternaria leaf spot in apple.

During fruit development (20 days after 4th spray)

  • The sprays of propineb @ 0.3% (600gm/ 200L water) or zineb @ 0.3% (600gm / 200L water)are recommended for the management of apple scab.
  • Tebuconazole 50% + trifloxystrobin 25% WG @ 0.04% (80gm/ 200L water) is recommended for the management of premature leaf fall.
  • Carbendazim 25% + flusilazole 12.5% SC @ 0.08%(160ml/ 200L water) is recommended for the management of premature leaf fall and Alternaria leaf spot in apple.

The advisory further said that this year, two new fungicides namely Cursor 40%EC (flusilazole 40%EC@ 0.025%) (50ml/200L water) for apple scab at petal fall/ pea stage, and Lustre 37.5% SE (carbendazim 25% + flusilazole 12.5% SE@0.08% (160ml / 200L water) for premature leaf fall and Alternaria leaf spot at petal fall/ pea stage and fruit development (20 days after 4th spray) have been added after evaluation.

Flusilazole is a fungicide with curative and preventative activity. It is a potent inhibitor of sporidial growth and acts by inhibiting ergosterol biosynthesis through direct inhibition of the 14α‐demethylation of ergosterol precursors. Carbendazim is a broad-spectrum systemic fungicide with protective and curative action. It is taken and translocated within the plant as a result of which the latter become fungitoxic. It mainly acts by inhibiting the development of germ tubes, the formation of appressoria and the growth of mycelia.

The advisory said that the use of new combinations of fungicides exhibits systemic activity, provides protectant, curative and eradicant control, and both the fungicides in these combinations have different modes of action. Therefore, such a new combination can delay or prevent the build-up of resistance in the pathogen and can be effectively utilized as a promising preventive fungicide for the control of apple diseases.

The university said that it also receives queries from farmers regarding the mixing of different insecticides/fungicides with fertilizers. However, the scientists from the Department of Plant pathology do not recommend these as it can create an adverse impact on plants.

The university has advised farmers to email their queries regarding different diseases with 5-6representative photos to ho dmpp@yspuniversity.ac.in or hodmpp2014@gmail.com so that these can be addressed by the department.

She had applied for a PhD with a scholarship in Forest Genetics which was advertised by INRAE. Naincy was successful in the interview and was awarded a fellowship for three years for pursuing PhD at the University of Orléans. During the course of the PhD, she will receive a total scholarship of around Rs 70 lakh along with medical reimbursement. Naincy will be working on forest tree larch species in the Project titled ‘Vigour at what cost? ‘Trade-off’ of hybrid vigour in Larch-Phenological, morphological and physiological determinants of hybrid superiority in Larix X eurolepis’ with a team of 20 scientists of Joint Integrated Biology Research Unit having expertise in genetics, genomics and physiology for the enhancement of tree and forest diversity

Dr. Parvinder Kaushal, Vice-Chancellor of the university spoke to Naincy via web conferencing and congratulated her. Dr. Kaushal, who has also done his doctorate from France, shared some tips and suggestions. He asked Naincy to explore this opportunity to learn about new cultures along with doing research that could help to enhance and conserve forest wealth in the future.
