What kind of pesticide do you use to grow potatoes?

Pesticides for growing potatoes need to be applied according to their growth cycle and symptoms of diseases and insect pests, for example, late blight can be sprayed with manganese zinc flumolin powder 500 times 800 times, virus diseases can use 40% omethoate 1000 times, ladybugs can use 10% cypermethrin EC 3000 times, to prevent grubs can use 80% trichlorfon wettable powder plus fine soil 1520 kg, make medicine soil scattered in the sowing ditch.

Second, the planting method of potatoes

1. Land selection and preparation

Try to choose the soil is more fertile, the soil is more loose, of which sandy land is the most suitable for potato cultivation. When preparing the soil, try to dig a little deeper, refine the soil, and then apply basic fertilizer.

2. Seed potato treatment

Seed potatoes should be taken out more than ten days before sowing and germinate at a certain temperature. when most potato buds grow to the length of their fingernails, move the potatoes outside for a week.

When sowing, cut the place where the potato has sprouts, and a potato can be cut into three or four pieces according to the situation of germination, stained with ash, and can be used to sow seeds. Planting should be carried out at certain intervals when sowing, and a fertilization should be carried out when planting, with farm manure as the main fertilizer as far as possible. Fertilizer should not come into direct contact with the seed lest the potatoes should be burned to death.

4. Field management

When the seedling grows 3-5 leaves, pay attention to the control of aphids; fertilize once at the early budding stage and at full flowering stage, generally add urea or 1% of potassium dihydrogen phosphate and dilatonin; pay attention to strengthen field irrigation during the expansion period of potato pieces.

As pesticides have a certain degree of toxicity, we choose excellent varieties when planting potatoes, which can reduce the production of diseases and insect pests, thus reducing the use of pesticides.
