Pepper is also known as horned pepper, long pepper, vegetable pepper, lantern pepper, Solanaceae, pepper belongs to one-year or limited perennial herbs. So when was it introduced into China? Blossom sitting fruit long mite, what medicine does lobular disease hit? What are the influencing factors of planting benefit?

Archaeologists estimate that the Mayans began to eat chili peppers in 5000 BC. However, for ancient China as far away as China, pepper did not enter China until the end of the Ming Dynasty.

What medicine does chili blossom sit fruit long mite, lobular disease hit?

1. Blossom and fruit setting:

Diseases such as bacterial wilt and navel rot are easy to occur during flowering and fruiting stage. the diseases need to be prevented in advance and soil moisture should be controlled at the same time. At the same time, the nutrition consumption during flowering and fruit setting period is very large, so it is necessary to promote flowering, increase fruit setting rate and promote pepper expansion, and supplement more trace elements such as phosphorus, potassium, calcium, boron, zinc and so on. Phosphorus and potassium is conducive to fruit development and expansion, calcium increases pepper hardness, reduces navel rot, promotes root development, boron and zinc promote flowering and strong flowers, increase fruit setting rate, and apply micro-root calcium + micro-supplement energy. Foliar spraying micro-supplement flower power + micro-supplement fruit power, reduce the use of high-nitrogen fertilizer, prevent luxuriant branches and leaves and affect flowering and fruit setting.

2. Long mites:

When the damage is found in the field, it should be controlled by spraying when the rate of leaf curling in the field reaches 0.5%. The following insecticides can be used for control: 20% diformamidine EC 1000ml 1500 times; 15% dicarboxylic acid EC 15003000 times; 5% acarate suspension 2000m 3000 times; 1.2% nicotine matrine EC 1000m 2000 times; 5% thiabinone EC 20003000 times 30% acarate suspension 2000 murine 3000 times liquid; 10% liuyangmycin EC 1000 murine 2000 times liquid; 50% bromoacarate EC 1000 murine 2000 times liquid; spray water, in order to improve the prevention and control effect, you can mix synergists or washing powder in the solution, and use eluent spray. When spraying, focus on spraying the young parts of the upper part of the plant, such as the back of tender leaves, tender stems, flower organs, young fruits and so on. The protected land can be fumigated with 10% fumigant 400 murine 6009 / mu.

3. Lobular disease:

① is used to control virus-transmitting insects. At the initial stage of the disease, any of 40% dimethoate EC 1000 times, 40% valerate EC 6000 times, and 2.5% deltamethrin EC 3000 times was sprayed once every 7 to 10 days for 2 times.

② is used to prevent and cure virus. 72% virulent 100x solution or NS-83 resistance enhancer developed by the Department of Plant Protection of Beijing Agricultural University was sprayed once every 7 days, twice in a row.

③ medicine and fertilizer were sprayed together. Spraying with chlorpyrifos microemulsion + Avidaben + aminooligosaccharins should be carried out after 16: 00:00 in sunny or cloudy days, and the twigs, leaves and stems should be sprayed through, mainly on the back of the leaves, once every 5-7 days, for 3 times in a row, the occurrence of "lobular disease" of pepper can be controlled.
