Pumpkin crops in the open field are threatened by many pests. Cucumbers, zucchini, squash can significantly lose in the harvest, if the gardener does not bother to repel the attack of parasites in his beds in time. Who should be wary of in the first place and how to protect your pets from harmful insects?
Sprout flies: how to protect crops and seedlings?
Sprout flies are a dangerous enemy for pumpkin from the first days of sowing crops. In addition, it harms legumes, sunflowers, corn, onions. Their larvae begin to damage already germinating seeds, and also destroy cucumber seedlings. They bite into seeds and grains, piercing the hypocotal knee with their little body, which causes seedlings to die, and seedlings noticeably thin out.
To protect the planting from the parasite, it is very important to carry out pre-sowing treatment of the seed. In addition to seed dressing, the soil should be treated. Be sure to dig the site in a timely manner. Also, the harmful effects of germ flies can be reduced by spraying with a suspension of colloidal sulfur.
Spider mites are afraid of garlic and onions
A spider mite causes a lot of trouble for summer residents. It settles not only on pumpkin seeds, but also harms peppers, tomatoes, and affects indoor ornamental plants. It hides on the underside of the leaf plates of plants, its presence is signaled by a thin cobweb in this part.
The activity of the parasite increases with the onset of hot dry weather, but they begin to fight it back in winter, when it still peacefully coexists with humans, hiding in greenhouses and other premises. To prevent its harmful effects, it is recommended to fumigate the area with lump sulfur. This measure is effective for controlling hibernating females. When the pest has become more active, a biological method of influencing the population is used in greenhouses - its natural enemy, the phytoseiulus tick.
An effective folk remedy in the fight against spider mites is spraying plantings with infusion of garlic, onion peels. For this, 200 g of raw materials are required for 10 liters of water. Treatment with colloidal sulfur also helps. In addition, the plants are pollinated with ground sulfur.
Whitefly runs from henbane and dope
Whitefly is a frequent visitor to buildings such as greenhouses. In addition to cucumbers, she will not fail to infect salad and celery with her larvae, and beans are not deprived of attention. The harm from the appearance of this parasite on the beds is double: the whitefly not only feeds on plant sap, but also produces sticky secretions in the process of its activity, which become a favorable environment for the development of sooty fungi, which in turn cover the plantings with a black bloom.
Insecticides are used against parasites, for example, actellik (20 g per 10 liters of water). Water infusions of such plants as common dope, black henbane help to fight whitefly. Another method of fighting the parasite that is absolutely safe for humans, but destructive for the whitefly, is the use of encarsia, which is the natural enemy of a harmful insect.
Wash melon aphids with soap
The insect harms a wide range of garden crops, both pumpkin and nightshade: cucumbers and zucchini, pumpkins and watermelons, zucchini and dill, peppers and eggplant. Aphids infect flowers, ovaries, shoots, leaves. As a result, parts of plants are deformed - shriveled, twisted. The pest is especially active in moderately humid and warm weather. In addition, aphids are a carrier of viral pathogens.
An effective way to get rid of melon aphids is to spray the infected plantings with a solution of laundry soap. To do this, take 150-200 g of shavings per 10 liters of water. They also use a solution of soapy water with wood ash - 50 g of soap and 200 g of ash will be needed for the same volume of water.
