Plant-Specific Program

Annual foliar nutrition program for walnut (Updated 2022).

Walnut

Purpose of the Program

This program is a combined foliar nutrition program prepared without basing it on soil and/or leaf analysis, composed of the macro and micro plant nutrients that the plant will optimally need throughout the season. All products recommended within the program are mixable and should be mixed in the given order. A jar test is recommended before application. The programs are advisory in nature and may be modified according to soil or leaf analyses. Any liabilities arising from applications belong to the user. The insecticides, acaricides and fungicides to be used during applications must be licensed products recommended by the Ministry. Liability for products used other than those produced by Agrotroia belongs to the user.

Warnings

  • The products specified in the program must be mixed with water in the given order (1-2-3-4, etc.).
  • It is recommended to carry out the application in the evening hours or on mornings without dew.
  • There should be no rainfall for an average of 4 hours after the application is made.
  • This nutrition program may not be copied without permission, used for purposes other than intended, or quoted.
  • Agrotroia reserves the right to make changes to the nutrition program without notifying its affiliates.

Stage-Specific Application Program

Step-by-step, balanced nutrition applications according to the plant's growth stage.

Application 1
1Application

1st Application Period

(After Harvest)

  • 100 L Water / 1000cc Copperas (5% Copper Sulfate + organic acid + L-amino acids)
  • 100 L water / 250-400 g B-Zinc (Boron 11% + Zinc 8% + Manganese 2%)
  • 100 L water / 250 cc Florista (5-20-0 + Zinc + Manganese)

Purpose of the Application: To minimize the effect of the harvest process on the plant, which emerges exhausted after harvest, to ensure the maturation of newly formed fresh shoots, and to prepare the plant for the coming season.

2Application

2nd Application Period

(When the Leaves Fall)

  • 100 L Water / 1000cc Copperas (5% Copper Sulfate + organic acid + L-amino acids)

Purpose of the Application: It is used to ensure that our trees preparing for winter dormancy go to sleep in a healthy way and to minimize the problems that will arise upon awakening. After this application is carried out, there is no need to use various copper-based products for winter care. The 5% copper in its content is sufficient to meet the plant's copper requirement.

3rd Application Period

(End of Winter Application)

  • 100 L Water / 750cc Copperas (5% Copper Sulfate + organic acid + L-amino acids)
  • 100 L Water / 400cc Phosforico (0-9-11 phosphite-based)

Purpose of the Application: As sap rises again in the plant, the plant will begin to become active for a new production season; the first reaction will be the swelling of the fruit buds. The copper and phosphite ions provided in this period will strengthen the plant's immune system and it will gain resistance against various fungal diseases.

4th Application Period

(As the Male Flowers Begin to Open)

  • 100 L Water / 250cc Activo (Organic + inorganic acid complex pH reducer)
  • 100 L Water / 250cc Oceano Mix (Fortified liquid seaweed + 17 amino acids)
  • 100 L Water / 250 gr Combi (Chelated combined micronutrient (B, Cu, Fe, Mn, Mo, Zn))

Purpose of the Application: It will increase the quality of the fertilizing pollen in the male flowers and pollination will be healthy. This application, which has serious effects on fruit set, must absolutely be carried out. It will also encourage healthy formation for the female flowers. It will increase the plant's ability to produce leaves.

Application 5
5Application

5th Application Period

(When Fruit Set Occurs)

  • 100 L Water / 500cc Copperas (5% Copper Sulfate + organic acid + L-amino acids)
  • 100 L Water / 250cc Calcio (Calcium (CaO) with uptake facilitated by propionate)
  • 100 L Water / 250 cc Oceano Mix (Fortified liquid seaweed + 17 amino acids)

Purpose of the Application: This is an application that should be carried out to ensure healthy fertilization of the female flowers and to prevent early fruit drop. Early anthracnose control is important for problems that may occur in later periods.

Note: Anthracnose control, detection and control of the codling moth.

6Application

6th Application Period

(Fruit Development Period)

  • 100 L Water / 500cc Copperas (5% Copper Sulfate + organic acid + L-amino acids)
  • 100 L Water / 250cc Phosforico (0-9-11 phosphite-based)
  • 100 L Water / 250 gr Combi (Chelated combined micronutrient (B, Cu, Fe, Mn, Mo, Zn))

Purpose of the Application: Together with fruit set, Copperas will increase the plant's immune system against harmful pathogens and the effect of the fungicide to be used for anthracnose. Early anthracnose control is important for problems that will occur in later periods.

Note: Anthracnose control, detection and control of the codling moth.

7Application

7th Application Period

(Fruit Development Period)

  • 100 L Water / 500cc Copperas (5% Copper Sulfate + organic acid + L-amino acids)
  • 100 L Water / 250 gr SuperDrop 20-0-28 (20-0-28 + 2% MgO)
  • 100 L Water / 250cc Vital (5-11-11 + Micro Element + Amino Acid)

Purpose of the Application: During the fruit development process, Copperas begins to play an important role for the plant. It strengthens the resistance system of trees laden with fruit. With the solstice, Vital prevents possible sunburn. With the potassium in Drop, it will be effective in kernel filling and growth.

Note: Detection and control of the codling moth and spider mites.

8th Application Period

(Fruit Development Period)

  • 100 L Water / 250cc Copperas (5% Copper Sulfate + organic acid + L-amino acids)
  • 100 L Water / 250cc Phosforico (0-9-11 phosphite-based)
  • 100 L Water / 250 gr Combi (Chelated combined micronutrient (B, Cu, Fe, Mn, Mo, Zn))

Purpose of the Application: Copper ions provide resistance to the plant, whose defense mechanism declines as temperatures rise, and create a defense against harmful pathogens. Phosforico, together with Copperas, will support shoot formation. Combi is of vital importance for the exhausted plant in this period.

Note: Final anthracnose control, detection and control of spider mites and aphids.
