Juicy zucchini to taste not only to humans, but also to numerous pests. Compared to cucumbers, zucchini are more resistant to diseases, but they also do not bypass the plantation. And if diseases with a high degree of probability can be avoided with prevention and proper agricultural technology, then pests become uninvited guests, from whom it is difficult to get rid of. What methods of processing zucchini should be used to get rid of these misfortunes?
Crop rotation and helper plants
First of all, it is important to adhere to the rules of crop rotation of plants in the beds. Since vegetables from the same family are most often affected by the same diseases, it is not recommended to plant them in one place for several years in a row. So, when late blight was noticed on tomatoes last year, sweet peppers cannot be planted here this year, since these vegetables belong to the same family. If the cabbage had a keel, it is contraindicated to plant radishes in this area. However, nightshades (tomato, pepper, eggplant) and crucifers (cabbage, radish, daikon) are good predecessors for squash and other pumpkin seeds.
In addition, some plants help repel many harmful insects. Uninvited guests are greeted with such flowers: daisies, marigolds, asters, nasturtium. The melon aphid does not like planting garlic, chives, mustard, fennel, basil, peppermint in the neighborhood. The cucumber beetle does not want to spread to the pumpkin beetle where it smells the radish.
Pre-sowing seed treatment should not be neglected. Such measures significantly increase plant resistance to disease and disinfect infected seeds. In addition, the seeds must be full-bodied, of the correct shape and size. It is frivolous to believe that a strong, fertile plant will grow from a sick small seed.
Treatment of beds against diseases
The above measures are effective, but not always able to protect your pets from diseases and pests. What other tools need to be kept ready in order to process zucchini on time:
• Easy to find out
powdery mildew on whitish spots on the leaves. A double treatment with sulfur powder will help to get rid of it.
•
Peronosporosis makes itself felt with pale green and yellowish spots on the leaf plate. A preventive measure is the treatment of seeds with a solution of potassium permanganate. When a disease occurs in the beds, the squash is treated with Bordeaux liquid.
•
Bacteriosis manifests itself as brown spots on the leaves, damage and deformation of the fruit. Preventive measures are pre-sowing disinfection of seeds and treatment with Bordeaux liquid, copper oxychloride.
• From
gray rot it is necessary to get rid of radically - diseased tissues are cut out, and the sections are treated with a mixture of crushed chalk and copper sulfate. In addition, the beds with zucchini should be sprayed with an aqueous solution of a mixture of urea, copper sulfate and zinc sulfate.
•
Anthracnose develops in the form of circles of brown and pink spots throughout the plant. The more severe the degree of the disease, the larger the affected area. Dents appear on the fruit, and the leaves dry out. Increased humidity becomes favorable conditions for anthracnose damage, therefore it is important to observe the irrigation regime and regularly loosen the soil. Infected beds are sprayed with Bordeaux mixture, colloidal sulfur.
How to deal with pests
It is also important to take timely measures in the event of an invasion of parasitic insects on zucchini plantings.
In particular:
• Get rid of
melon aphid spraying with soapy water, karbofos, treatment with powdered sulfur will help.
•
Spider mite does not like the infusion of sharp feathers with soap and wood ash.
•
Whitefly will have to be washed off the leaves.
Since many pests hibernate in the soil, for prevention, it is imperative to dig the site.
