The rising trend of the tomato brown wrinkled fruit virus in recent years is one of the serious challenges facing tomato cultivation today, severely constraining the production and quality of tomatoes, and sometimes even the size of the shed, in terms of benefits。
Tomato brown wrinkled fruit virus
Mainly the following:
1. Symptoms of fruit: brown wrinkles, dimples or bumps on the surface of fruit, whose shape may be irregular and seriously affect the appearance and quality of fruit。
2. Symptoms of foliage: the symptoms of foliage on tender leaves and top buds are more visible, some of which are ceremonial, some of which are narrower, some of which are severe, and even worse, and some of which are less visible than in fruit。
3. The whole plant is slow to grow and is emptied。
Standardized management controls
1. Selecting anti-virus varieties, increasing the use of live pelican proteins for bottom fatting, and developing strong strains。
2. In general, the environmental conditions conducive to the occurrence of viral diseases are high temperatures and droughts, with the delayed planting of autumns covering sunnets during periods of high temperatures to prevent atrophy of young children. Owing to high temperatures and high water evaporation levels in the sheds, young seedlings are prone to atrophy due to water scarcity and to infection with the virus。
In the event of the discovery of a baby seedling, the timely spraying of the fruit-spray 4 1/2-1 package or a rejuvenation agent of 300-500 ml + zi稷禾僖 1-2 packs will be performed to promote the healthy growth of the baby。
3. Flowing of wind coverings to avoid wind blowing out of the plant, strengthening of temperature control in the sheds to ensure, as far as possible, a suitable temperature for tomato growth, and avoiding cross-infection in the whole branch。
Cut off the source of the insect, and trap yellow viscous plates below the growth point of the plant. There are also 100 worm-proof nets in front of the shed and on top of the shed, cutting off access, such as smoked lice, and cleaning of weeds in the fields and reducing the infestation of pests such as powdered lice。
5. Conventional antivirals (combinant + amino-vellose) combined with the precipitous application of zinc, calcium and fertilizers to ensure greater tomato growth and increased resistance to strains。
6. Tomato growth is carried out with long-term rejuvenation agents, variable spraying, 5-7 days of continuous spraying, and 2-3 times with long-term rejuvenation to increase the resilience of plants。
Strictly operating above to reduce the risk of delayed tomato viruses in the autumn and to lay the groundwork for fruitful harvests。
