• Soda from wasps is used during the ripening period of the berries, when chemical protection is prohibited. Soda solution increases the sugar content of the berries, prevents the formation of rot, promotes healing of the berries after punctures with insect proboscis, helps to discard wasps. At 10 liters of cold water will need 5 tbsp. tablespoons of baking soda, 20 ml of liquid soap. To process the grapes from wasps should be in the evening or early in the morning.

• The solution of baking soda with soap and water can protect against the attack of a berry. The tool enters the body with a bite, repels bitter aftertaste. In the stomach, soda causes increased gas formation, which is dangerous for insects to die. Spraying is carried out at any stage of the growing season. You can spray the solution using a household spray bottle, spray bottle.
