Disease control

In July, climate change intensified in the north and south, hot and dry in the north and rainy in the south. Under such a climate environment, agricultural diseases and insect pests have also entered a stage of large-scale, multi-type, and rapid spread. In order to ensure the healthy growth of crops and ensure the yield and quality of grain, oil, fruit, vegetable and tea, we suggest that field management should be strengthened and plant protection measures should be fully implemented.

climate characteristics of the southern region:
July is the rainy season in the southern region, which is often accompanied by extreme weather such as heavy rains and heavy rains, resulting in serious water accumulation in the fields and a large increase in humidity. The environment of high temperature and high humidity provides favorable conditions for the breeding of various diseases and insect pests.

disease control plan

Possible diseases:

1. Bacterial diseases: diseases such as rice bacterial streak disease and white leaf blight will spread faster after heavy rain due to high humidity and many wounds in the field.

2. Fungal diseases: rice sheath blight, corn sheath blight, soybean root rot, sweet potato root rot, etc., which are prone to occur and spread due to high humidity and accumulated water.

3. Insect pests: migratory pests such as rice planthopper, rice leaf roller and grassland noctuid will migrate in large numbers after heavy rain, causing serious harm to rice, corn and other crops.

Disease Control Suggestions

1. Drainage and dehumidification: timely dredge channels and discharge accumulated water in the field.

2. Chemical prevention and control: seize the opportunity of sunny weather to organize field chemical prevention and control. It is recommended to use berberine, zinc thiazole, thiazone and other chemicals to prevent bacterial diseases. Use carvacrol, rhein, jinggangmycin and other fungicides to control fungal diseases; Use matrine, pyrethrin, nitenpyram and other insecticides to control insect pests. Organic farms need to use organically evaluated Physcion and Carvacrol, Pyrethrins, Matrine

3. Intertillage loosening soil: water drainage field, timely intertillage to improve soil permeability, restore crop root activity.

4. Scientific medication: try to choose high activity, high content of single agent products, reduce the low content of compound agent, in order to slow down the resistance.

5. Strengthen the measurement and reporting: observe the occurrence of diseases and insect pests in the field and take timely prevention and control measures. Special attention is paid to the investigation of roots and stem bases.

northern region climate characteristics:

High temperature and drought in July, some areas may have sustained high temperature and little rain. Lead to crop water evaporation, soil water shortage, plant growth is blocked.

disease control plan

Possible diseases:

1. Physiological diseases: such as leaf wilting and fruit dropping caused by drought. Most of the causes of disease treatment are in root soil.

2. Virus diseases: Under high temperature and drought conditions, crops are weak and prone to virus diseases, such as tomato virus disease, cucumber mosaic virus disease, etc.

3. Insect pests: aphids, red spiders and other R pests multiply rapidly under high temperature and drought conditions, which aggravates the harm to crops.

Disease Control Suggestions

1. Irrigation and water supplement: comprehensively promote the integration technology of water and fertilizer, and timely supplement water and fertilizer according to the moisture content and crop growth to ensure sufficient soil moisture.

2. Spraying foliar fertilizer: spraying amino acids, potassium dihydrogen phosphate and other foliar fertilizers to enhance crop drought resistance. Organic planting can use Qingyuanbao amino acid water soluble fertilizer foliar spraying or water and fertilizer integration drip irrigation.

3. Pest control: regular agriculture can use imidacloprid, abamectin and other pesticides to control aphids, red spiders and other pests. Organic cultivation requires the use of matrine, rotenone and pyrethrins and other botanical pesticides that meet international organic standards.

4. Virus disease prevention: strengthen field management, observe crop conditions in time, remove diseased strains in time to reduce virus transmission sources, and use Qingyuan Baobao 0.1% Physcion Foliar Spraying or integration of water and fertilizer.

5. Reasonable rotation: the next crop as far as possible reasonable rotation, reduce the risk of pests and diseases caused by single crop planting.

 

 

Different regions face different diseases due to different climatic conditions. Growers should take targeted control measures according to local conditions to ensure the healthy growth of crops. At the same time, strengthen field management, improve crop resistance, reduce the occurrence of pests and diseases. In the process of prevention and control, pay attention to scientific drug use to avoid environmental pollution and crop damage caused by excessive use of pesticides.
