The need for crop protection
Wasps begin to show activity even in early spring, but become noticeable to humans in the summer. Insects feel the vineyard with juicy berries for several kilometers. Wasps pierce the berry, suck the juices. They have the peculiarity not to eat out completely one, but to bite a few.
On a note!
A dozen wasps can cause significant damage to the whole plantation of grapes. Because the public insects they transmit signs to each other, in a few days a whole swarm will visit the garden.
Damaged berries begin to deteriorate, rot. In the absence of a proper reaction on the part of a person, grapes lose their presentation, quality, and yield will significantly decrease. It is forbidden to use insecticides on already formed clusters; hanging traps does not give 100% of the result of protection. One of the best options is a protective net for grapes from wasps.
What is made of
Many firms produce products, but the product is not much different from each other. They are made of modern thin but durable polypropylene. Safe material, environmentally friendly, with high functional abilities. It does not get wet in the rain, does not melt under the hot rays of the sun. With proper use, careful storage will last several years.
On a note!
Nets from wasps pass air well, do not interfere with the natural ripening of grape berries. Protect from the negative effects of ultraviolet radiation by scattering rays. Size is selected individually depending on the grape variety, size - 1, 2, 3, 5, 10 kg.
Application features
Protecting grapes with pouches is one of the most effective methods that does not require special preparation or skills. A mesh is pounced on each bunch. Tightened at the top with special clamps. It can be a twig, a flexible wire, a cord.
They put on bags when the berries begin to collect sugar, become attractive to wasps. There is a deadline for each grape variety, so you need to monitor the condition of the clusters. A bag of wasps and birds should be wider and longer than clusters so that insects could not get to the berries, confused in a fine-mesh net.
On a note!
Attach to the vine from above so that the bag does not slip. Put on in the direction from bottom to top. Take into account the average size of the clusters in the formed form. There should always be stock. If the bag becomes cramped, the wasps calmly get through the cells to the berries.
Method effectiveness
A simple device protects the grapes, improves the conditions for ripening, and resists decay. The undoubted advantage is absolute safety for the person, environment. Bags from wasps are convenient to use, it is possible to use several seasons.
On a note!
The protective method is more suitable for small plantations with an area of 40 square meters. mYou need to put on a mesh for each bunch, which requires some effort, time. Using bags in large vineyards is financially unprofitable. A package of 50 pieces on average costs 600 rubles. Some get out of the situation, sew a protective structure with their own hands.
How to make a bag yourself
The most convenient material is a nylon mesh. Buy at a hardware store or fabric department. Other materials at hand are tulle, mosquito net, nylon tights, durable white agrofibre.
You can sew the bags manually or use a sewing machine:
- A flap of the right size is cut out - an average of 35 * 25 cm.
- Making a bag is very simple. It is folded, sewn, one side should not be stitched, a rope or cord is threaded there to tighten the bag, tie it to the vine.
How long it takes will depend on the right amount of finished product.
Longer bags from wasps from durable agrofibre, nylon mesh, purchased in a store, mosquito net, tulle will last longer. Old tights are enough for one season, they are less effective, used in a hopeless situation.
Important!
It is not recommended to sew from gauze, because after rain it clumps, sticks, causes rotting of berries.
As for the complexity, financial costs - do-it-yourself pouches are not much cheaper, but it takes time to make them. It’s more profitable to buy ready-made ones, but the vine-grower himself makes the choice, which is more convenient for him. Used correctly, it’s enough for several years. Products are sold in specialized stores, it is possible to order online.
