1. Rice Blast Disease

Rice blast is one of the most important diseases of rice, which can cause a significant reduction in yield, and in severe cases, the yield can be reduced by 40% to 50%. The disease occurs in paddy fields all over the world and mainly damages leaves and nodes. It can cause early neck burst of rice, and then cause yield reduction.

Symptoms:

Seedling Blast: occurs before clover in the way of the seed infection. Disease seedling gray base, the upper brown. If humidity is high, disease would generate a lot of gray and black mildew layer.

Leaf Blast: small, dark green spots appeared on leaves, gradually expanded to fusiform spots. Spots central is gray, brown edges, with pale yellow halo at outside.

Acute type of lesion: On leaves form a nearly round or oval, dark green spots. White spot lesion type: leaves after damaged, will produces small white nearly round spots, does not produce spores.


Occurrence Regularity:

1. Pathogens overwinter on diseased straw, rice stumps, and diseased grains, and are the primary source of infection in the following year.

2. The prevalence of rice blast is affected by factors such as climate, variety, cultivation, etc. The bacteria will multiply and infect faster at temperatures around 25°C. Rice is more likely to be infected when the average relative humidity is above 90% or even saturated.

Solutions

CHICO has accumulated rich experience and could offer the corresponding high-class solutions, e.g.: TRIPO, FENOX.

2. Rice Sheath Blight

Rice sheath blight is caused by infection by Rhizoctonia solani. The disease mainly occurs on leaf sheaths and leaves.

Symptoms:

At the early stage of the disease, oval and dark green water-soaked lesions first appeared on the leaf sheaths close to the water surface, and then gradually expanded into a moiré shape, with gray-white in the middle, and gray-green when wet.


Occurrence Regularity:

Rice sheath blight can occur from the seedling stage to the ear stage. Generally, the disease starts at the peak tiller stage, accelerates at the jointing stage, reaches the peak before and after the booting stage, and declines at the milk maturity stage. The disease is more severe in periods of high temperature and high humidity.

Solutions

CHICO has accumulated rich experience and could offer the corresponding high-class solutions,e.g.: TRIPO, CAZOLE.

3. Rice Smut

Rice smut is a disease caused by the infection of Sclerotinia oryzae. The disease occurs only in the ear of rice, and damages the grain. Rice false smut is one of the main diseases of rice. It is distributed in rice producing areas of the world. The general incidence rate is 3-5%. In severe areas, the incidence rate can reach more than 30%, and the yield can be reduced by 20-30%.

Symptoms:

It first exposed small yellowish-green fungus at the joint of the glume, which gradually expanded, and finally wrapped the whole glume, which was dark green or olive, and finally cracked, and the rice ears were covered with dark green powder.


Occurrence Regularity:

1. The rice false smut pathogen can overwinter by the sclerotia that fall into the soil or the chlamydospores attached to the seeds, and become the primary infection source of the following year.

2. The incidence of rice false smut is closely related to varieties, fertilization and climatic conditions. From the formation of young ears to the booting stage, if there is heavy rainfall and high humidity, and low temperature rainfall during flowering, the incidence rate will increase.

3. Large amount of nitrogen fertilizer application, flooding, cluster irrigation and flood irrigation are also the main reasons for the spread of rice smut.

Solution

CHICO has accumulated rich experience and could offer the corresponding high-class solutions,e.g.: TRIPO, AZOTEL.

Rice Pest Control

  • crop giant foliar fertilizer for rice
  • fertilizer application in rice

1. Rice Planthopper

Rice Planthopper belongs to Homoptera. It harms rice by sucking plant sap. There are three types of planthoppers: the brown planthopper, the white-backed planthopper and the white-backed planthopper.

Symptoms:

1. Adults and nymphs suck the rice and cause the plants to turn yellow.

2. The excrement of rice planthopper often leads to the growth of mold, which affects the photosynthesis and respiration of rice.

3. Rice planthopper can spread rice bush dwarf disease, rice black-streaked dwarf disease, rice stripe blight and so on.

Solution

CHICO has accumulated rich experience and could offer the corresponding high-class solutions,e.g.: NIPPY, TOPACE.

  • fertilizer for paddy

2. Rice Stem Borer

Rice Stem Borer belong to Lepidoptera pests. It is one of the main pests in rice.

Symptoms:

1. Eat the stems of rice, damage the rice in the tillering stage, and cause withered sheaths and withered heart seedlings.

2. It damages the booting and heading stage of rice, causing withered booting and white ears.

3. Damage the rice in the grain-filling and milk-maturing stages, causing semi-withered ears and insect-injured plants.

4. Injured plants are clustered in the field.

Solution:

CHICO has accumulated rich experience and could offer the corresponding high-class solutions, e.g.: ABADI 33%WP, MAXIUM 24%SC, IMMOTAP 62%WP.

  • fertilizer for rice field
  • fertilizer for rice growing

3. Rice Leaf Roller

Rice Leaf Rollers, also known as scraping caterpillars, white leafworms, bracts, etc., are one of the main pests of rice.

Symptoms:

1. Harm rice with larvae, roll the leaves into vertical buds, hide in them and feed on the upper epidermis and mesophyll, leaving only the white lower epidermis.

2. If the rice is damaged at the seedling stage, it will affect the growth and even die.

3. If the rice is damaged from the tillering stage to the jointing stage, the tillers will be reduced, the plants will be shortened, and the growth period will be delayed.

4. If the rice is damaged after booting, it will affect flowering and fruiting, increase the empty shell rate and decrease the thousand-grain weight.
