Prevention and treatment of tomato peel

Today I will tell you about the prevention and treatment of tomato flower skin, so we don’t have to worry about encountering such a problem again:

(

1) Physical prevention of tomato peel

High-temperature disinfection of soil: It is carried out during the high temperature period of the three summers. After pulling the seedlings in the protected land in spring, clean the fields first, remove the diseased plants, diseased leaves, and diseased roots from the fields and bury or burn them deeply; apply 50-100 kg of lime and 1,000 kg of broken straw (or wheat straw) per mu, evenly apply them on the surface; deep plow the soil to 66 cm, super high ridges to 33 cm, irrigate, and keep the furrows full of water; lay the ground film and seal the shed for 7-10 days to prevent and control cucumber wilt, blight, root-knot nematodes, etc.

Baking soda or high-fat film to prevent powdery mildew: When powdery mildew just occurs, spray 500 times of baking soda solution, once every 3 days, for 5 to 6 times in a row, which can not only prevent powdery mildew, but also decompose carbon dioxide and increase cucumber yield. Or use 80 to 100 times of 27% high-fat emulsion, spray once every 6 days, for 4 times in a row. (3) Yellow board to attract aphids or silver-gray film to avoid aphids.

(2) Biological control of tomato peel

Disease prevention: For powdery mildew, anthracnose, and black spot, when individual spots first appear, spray 2% agricultural anti-120 or agricultural anti-B0-10 water solution 200 times, spray once every 6 to 7 days, spray 4 to 5 times in a row, and can also treat gray mold and downy mildew. In the early stage of bacterial diseases, such as angular leaf spot, spray 100 times of agricultural anti-751 water solution, spray once every 5 to 6 days, spray 2 to 3 times in a row.

Pest control: When cucumber aphids occur, you can spray Shaoguanmycin 200 times diluted, add 0.01 neutral laundry detergent, or use 0.65% artemisinin 200 ml, add 60-80 kg of water for spraying. For tea yellow mites, you can spray 20% compound Liuyangmycin 800-1000 times diluted, spray once every 6-7 days, and spray 2-3 times in a row.

(3) Tomato peel control with chemicals

For protected tomatoes that have already fallen ill, pesticides with high efficiency and low residual content can be used for proper prevention and control. Late blight can be treated with 60% Biotek or 80% Dasheng M-45 wettable powder or 72% Kelu wettable powder; gray mold can be treated with 5% cypermethrin dust or 50% cypermethrin wettable powder or 1000 times dilution of 50% cypermethrin No. 2; angular leaf spot can be treated with 5% anti-bacterial dust or anti-bacterial dust; black spot can be treated with anti-black mold dust or 40% Fuxing emulsifiable concentrate; anthracnose can be treated with 8% cypermethrin dust or 80% anthracnose Fumei wettable powder; aphids and whiteflies can be treated with anti-aphid and anti-lice dust or 10% imidacloprid wettable powder.

There's a reason why tomato fruits are hollow

Tomato hollow fruit refers to fruit with a hollow space between the peel and the jelly-like flesh. Although hollow fruit does not have a significant impact on tomato yield, it will seriously affect its commercial quality and reduce economic benefits, and must be taken seriously in production.

Tomato hollow fruit is a physiological disease, and varieties with a small number of ventricles are prone to it. There are many reasons for the formation of tomato hollow fruit, such as improper hormone spraying time, insufficient light, insufficient watering during the peak fruiting period, too many fruits left, insufficient supply of nutrients, etc. In order to avoid the occurrence of hollow fruits, tomato varieties with more ventricles should be selected in cultivation, and regulators should be used reasonably. When 2/3 of the flowers in each inflorescence are open, spray anti-drop agent with a concentration of 15ppm to 25ppm, and be careful not to reuse it. In addition, sufficient basal fertilizer should be applied during cultivation, and formula fertilization technology should be adopted. Topdressing and sufficient watering should be applied in time during the peak fruiting period to meet the plant's nutritional needs. The growth of each tomato variety is different, and the tips should be pinched in time according to the characteristics of each variety to balance the nutritional growth and reproductive growth of the plant.
