Diseases and pests of sea buckthorn are not so numerous. In Siberia, the most common pest of this plant is sea buckthorn moth. In the non-chernozem region there is a gall mite and sea buckthorn aphid. But the worst thing for the plant was a disease called "verticillar wilting."
Diseases and pests of sea buckthorn
Sea buckthorn moth
It lives in Transbaikalia. When the kidneys begin to swell, the caterpillars of the parasite creep inward, eating the core. In the summer months, caterpillars build their nests from the web, pulling together up to 6 leaves on the tops of the shoots. But they prefer to pupate in the soil. The end of July is the time for the appearance of butterflies from pupae, and after a month these butterflies lay new eggs on the bark of the trunk below the bush and in fallen foliage. They fight moths by spraying with "Chlorofos" even before the buds open.
Sea buckthorn fly
This is a very dangerous insect for sea buckthorn, which can destroy the crop completely. A fly lives in Altai. From the second half of June to the second half of August years of insects continue. The larvae of the parasite already a week after masonry begin to invade the fruits, eating their flesh. The berries become dark and shriveled, and then completely fall off. Three weeks later, the larvae move to the soil, where they pupate and winter. To combat the pest, the most effective way is to irrigate 0.2% of Chlorophos in the second half of July.
Sea buckthorn aphid
Diseases and pests of sea buckthorn are not so numerous. Sea buckthorn aphid has become one of these species. Affects the parasite foliage. For wintering, the aphid remains in the form of eggs next to the kidneys. When the buds open, the juice of young and tender leaves becomes food for the larvae. And when the leaves finally ripen, the larvae settle on their underside. Female settlers have wings, which allows them to fly to new territories and give life to new aphid offspring. Foliage damaged by a pest turns yellow early, curls and falls. These pests of sea buckthorn are destroyed by 10% Karbofos, and you can also spray with decoctions and infusions of potato or tomato tops, onion and garlic husks, tobacco leaves, adding a solution of laundry soap.
Sea Buckthorn Gall Mite
Diseases and pests of sea buckthorn include another representative - a tick. He prefers shrub foliage; for the winter he settles in the sinuses of the kidneys. The tick is very small (you can see it only under a magnifying glass), has a white color. The parasite literally drains young leaves, and then sucks the juice from ripened foliage, forming flat swellings - galls. Such foliage falls off early. It is necessary to deal with the tick in the same way as with aphids.
Disease
Verticillus wilting
This is the most serious disease that affects sea buckthorn. The diseases and pests described above are not as dangerous as verticillin wilt. Today it remains incurable. It is found in all regions of sea buckthorn cultivation. It was established that the pathogen overlaps the plant's conducting system, and the bush dies. In August, individual branches (or all of the foliage) turn yellow and fall, the berries wrinkle, swellings develop on the bark and then crack. The very next year, the plant dies.
