Below are some important points to note related to the spray of agrochemicals:
This spray schedule is for normal weather conditions.
In case of heavy rains within 12 hours of spray, the spray is to be repeated within seven days.
Do not repeat the same chemical for spray.
Pesticides should be sprayed when there are chances of diseases.
Do not mix Dodine with other pesticides/chemicals.
Do not mix any other pesticide/chemical/micro-nutrient/growth regulator/hormone with theabove recommended pesticides to avoid russeting and other disorders. When necessary, thesemay be sprayed separately.
The fallen leaves of apple should be collected and decomposed in a compost pit or 5% ureasprayed on orchard floor to ensure fast decomposition of infected leaves.
For the control of White root rot, drench the basin area 3-4 times, with Carbendazim (0.1%) or Aureofungin (0.05%) + Copper Sulphate (0.05%) with the onset of rainy season to a depth of 15-20 cm. During winters, expose the root system of infected trees to sun. Remove theinfected portion and apply Bordeaux paint.
For the control of Collar rot, scarify wounds near collar region and apply Bordeaux paint orany other Copper fungicide based paint during winter season. Drench the whole tree basin at adistance of 30 cm from tree trunk with Mancozeb (0.3%) during rainy season.
In scab prone areas 12-14 days’ interval should be maintained between the sprays up toprimary scab stage.
Use of Captan should be avoided before and after the oil spray for minimum 15 days.
Dodine should not be mixed with hard water.
Application of bio-control agents/bio-pesticides can be used against collar rot, root rot and rootborers.
Preventive measures for Apple diseases:a. Crown gall or Hairy root- Avoid injury to the collar region and rouge out infected plants and destroy them.b. Foliar Diseases-As the pathogen overwinters on the fallen leaves and therefore orchard sanitation by removing weeds and bushes and by removing the fallen leaf litter from the orchard floor, is one of the most important measures to reduce the initial inoculum. Adopt proper pruning of trees for adequate air circulation and rapid drying of foliage, thus prevents the development of secondary lesions in the orchard.c. Powdery Mildew-Prune off the silver terminals and destroy them. d. Canker These include removal and destruction of infected plant parts, mummified fruits, dead twigs and pruned branches, avoiding mechanical injuries, application of balanced fertilizers on the basis of leaf and soil analysis, proper irrigation during hot dry periods to avoid tree stress, protecting plants from high and low temperature injuries and ensuring effective control of insect-pests and diseases.
Recommendations for Hail damage: –
Spray 100 gm Carbendazim or 600 gm Mancozeb in 200 L of water immediately after hail.
Spray 200 gm Boric acid + 500 gm Zinc Sulphate + 250 gm Quick lime in 200 L of water within 3-4 days of hail storm.
After 10 to 12 days, a spray of micro-nutrients like Agromin, Multiplex or Microvit @ 400 to 600 g per 200 L of water is also recommended. Spray the hail affected apple orchard with 1 kg Urea in 200L of water.
Enhancement of Apple fruit size:
Need base application of Gibberellic Acid (GA4+ GA7)1.8%+Benzyladinine1.8% @30- 60 ppm can be applied on 80-90% king flower bloom stage for enhancement of fruit size (L:D ratio).
