Methods for Management of Paddy Crops

• PEST CONTROL

Pest monitoring should be carried out weekly and control measures should be taken if necessary.

1. Weed control: Identify the type, severity and intensity of weeds last season. Prepare the land perfectly. Use pre- and post-fertilization toxins. Control the water level so that the poison can act effectively. Monitor weeds and carry out weed treatment if necessary after 60 days until maturity.
   
   
   

2. Rice Paddy Control: Identify the distribution and intensity of wind rice in the past season. Implement proper soil preparation so that the rice paddy seed banks in the soil can be minimized. Use legitimate rice seeds that are free from wind paddy. Sprinkle rice seeds in water in areas with wind paddy infestation exceeding 10%. Use appropriate pre-fertilizer a day after sowing. Boil water so that poison can act effectively. Make sure the water level is 5 - 10 cm throughout the growth of the tree. Control the water level so that the poison works. Monitor the rice paddy and run the fertilizer after 30 days until maturity.

3. Planthopper (Nilaparvata lugens): Invades the early stages until the rice reaches 90 days after sowing. The attack caused yellow leaves and then a â € ˜hopper burnâ € ™. These pests need to be inspected weekly from the age of one month to make pesticide decisions. Spray with recommended insecticides if the population exceeds 20 adults / m2 or 200 nimfa / m2. 
   
   
    

4. Whitebacked planthopper (Sogattela frucifera): It attacks in the early stages until the rice reaches 90 days after sowing. The attack caused yellow leaves and then a â € ˜hopper burnâ € ™. These pests need to be inspected weekly from the age of one month to make pesticide decisions. Spray with recommended insecticides if the population exceeds 25 adults / m2 or 200-300 nimfa / m2.

5. Green planthopper (Nephotettix spp.): Carriers of the thyroid virus. In areas where there is no source of this virus, insecticide spraying is not required. In areas where the source of the virus is infected, spray insecticides are recommended in addition to culture controls to reduce the source of the virus.
    

6. Rice bug (Scotinophora coarctata) :Â Attack the early stages of the plant up to 90 days after sowing. The attack resulted in a yellow tree and then a â € ˜bug burnâ € ™ war. These pests should be inspected weekly starting one month after sowing. Spray with recommended pesticides if the population exceeds 2 adults / m2 or 10 nimfa / m2.

7. Rice ear bug (Leptocorisa acuta) and stink bug (Nezara viridua) : Attack on the rice-level paddy. The attack causes the rice to be empty or half full. Check this insect at the milk level. Spray with recommended insecticides if the population exceeds 2 adults / m2.

8. Bakanae (Gibberella fujikuroi) : Attacking at the beginning of the crop causes the tiller / tree to be attacked higher than the other blades. If it happened last season treat the seeds with a recommended fungicide.

9. Cercospora (Cercospora oryzae) : Attack at all levels of the plant. The subtle brown spots on the leaves, uplands, features and paddy skin. Spray fungicides if they are severe (5 - 10% attacks on plants in the lot).

10. Rice rotten neck (Pyricularia oryzae) : Attack at all levels of the plant. Invasion can occur on leaves, stems, stems and fruits, High use of N fertilizer, moisture and leaves covered with dew will encourage the attack. There are sharp oval / oval spots on the tip of the reddish orange on the edges and a grayish gray in the center. Do seed treatment before planting and spray fungicides recommended if severe attack (5 - 10% attack on plants in lot).

11. Rice bacterial blight pathogen (Xanthomonas oryzae) : Attack at all levels of the plant. The leaves are braided with small dots or wet strips. If the attack occurred last season, use rice varieties that are resistant to the disease.

12. Root rot disease of sugar beet(Rhizoctonia solani) : It attacks at all stages of growth, especially from the stage after childbirth to maturity. The gray / green part of the shed / leaf is green. There are sclerotia shaped like mustard seeds.  Spray fungal toxins at maximum bursting levels and bunting if severe attacks (> 10% attack on plants in lot).. 

13. Rotting stem (Sclerotium rolfsii) : Attack at the final stage of the crop. Uniform damage is seen in the leaf cavity at the water level. Over time it will cause damage to the gutter and stem. If an attack occurred last season, use rice varieties that are resistant to the disease and burn straw and stumps to reduce inoculum.
