How much does Kyoho grape cost per jin? A detailed guide to pest and disease control methods
Kyoho grape is a grape variety that is large in size, sweet in taste and high in yield, and is deeply loved by growers and consumers. Kyoho grape is planted relatively widely in the southern regions of our country and has fairly strong adaptability to the environment. Let us take a look below at how much the current Kyoho grape price is per jin, with pest and disease control methods attached.
1. How much is the current Kyoho grape price per jin?
The current Kyoho grape price is 4-8 yuan per jin, with certain differences among regions. From June all the way to September, throughout the summer market, it can be seen everywhere, going from farmers' orchards to the dining tables of every household. From 5 yuan per jin at the beginning of the season, to later 4 yuan and 3.5 yuan per jin, the overall price of Kyoho grape is very stable; it is just such an ordinary fruit, yet it has truly filled the pockets of farmers.
2. Pest and disease control methods for Kyoho grape
During its growth process, Kyoho grape is often infected by diseases, mainly including: downy mildew, white rot, rachis brown blight, gray mold, anthracnose, brown spot, powdery mildew, sour rot, and so on.
The main pests include: green plant bug, grape clearwing moth, two-spotted leafhopper, thrips, small white flower chafer, grape hornworm, and so on.
“Prevention first, integrated control” is the basic principle of grape pest and disease control. In grape production, it is necessary to observe the dynamics of pest and disease occurrence and development at all times, so as to achieve prevention in advance. Integrated control should be based on agricultural protection and preventive measures, and combined with local production realities, adopt a method combining chemical control, biological control and physical control to control the occurrence of pests and diseases economically, safely and effectively.
1. Agricultural control
Improve the soil environment. Through measures such as loosening the soil, weeding, mulching and reasonable irrigation, create a soil environment conducive to root growth and coordinated water and air.
Balanced fertilization. The growth and development of grapes require a variety of nutrient elements. Appropriately control the amount of nitrogen fertilizer and apply more phosphorus and potassium fertilizers and organic fertilizers.
Improve ventilation and light transmission conditions. During the growth process of grapes, pruning should be carried out regularly and reasonably, timely tying of vines, pinching of tips, removal of secondary shoots, appropriate thinning of leaves, and pruning of branches. Creating good ventilation and light transmission conditions can effectively reduce the occurrence of pests and diseases.
Clean the orchard. During the grape growing season, diseased leaves, diseased fruits and diseased vines should be removed in a timely manner and buried deep in a centralized way.
Deep plowing and weeding. Weeds in the orchard are the living environment and overwintering sites of pests and diseases, and timely removal can reduce the harm of pests and diseases.
2. Physical control
Make use of the specific responses and tolerance of fruit tree pathogens and pests to temperature, spectrum, sound and so on to kill or repel harmful organisms. For example, the virus-free grape seedlings currently advocated in production are obtained by using heat treatment to remove viruses. It is also possible to make use of the tropism of some pests by installing insect-killing lamps in the orchard or using sex attractants to trap and kill pests. Manual catching can also be adopted, which is simple, effective, economical and practical.
3. Chemical control
Scientifically and reasonably select pesticides, use advanced application equipment, grasp the appropriate control period, and adopt reasonable application methods. Pay attention to reducing the number of pesticide applications, the dosage, the use concentration and the safety interval as much as possible; the mixing of pesticides should be reasonable, and the ingredients should be clearly checked so that there is no conflict and no duplication. Pesticides should be used alternately to prevent the development of resistance and avoid affecting the quality and safety of grape products.
