Practical tips for preventing sprouting during potato storage
Symptoms: Also known as potato verticillium wilt or premature ripening disease. In the early stage of the disease, the leaf tips turn yellow along the leaf margins, and yellowing spreads inward from the leaf veins; later, the leaves dry up and turn from yellow to brown, but do not curl, until all compound leaves die without falling off. When the rhizome is infected, the initial symptoms are not obvious. After the leaves yellow, the vascular bundles at the cut rhizome have already turned brown, and later the aboveground stems...
The tips for preventing sprouting during potato storage are:To prevent potatoes from sprouting during storage, the following methods can be used.
① In the late growth stage (2-3 weeks before harvest), spray 2-3 g/kg of maleic hydrazide in the field;
② One week before harvest, spray the whole plant with 0.5-1 g/kg of 2,4,5-T to extend the dormancy period and storage period;
③ 2-3 weeks before harvest, spray the whole plant with a mixture of 3 g/kg maleic hydrazide and 0.3 g/kg 2,4,5-T; the effect of preventing sprouting is even better;
④ After the potatoes are harvested, spray methyl naphthaleneacetate onto dry soil, then mix the potatoes with the dry soil. For every 500 kg of potato tubers, use 10-15 g of methyl naphthaleneacetate;
⑤ Use a potato sprout inhibitor at a rate of 1.4 kg of sprout inhibitor per 1000 kg of potatoes, spraying it evenly on the surface of the potato pile to prevent sprouting.
