Akiochi
Akiochi
Early stage of Akiochi (Autumn decline in Japanese) Disease of water-seeded rice in California. Exact cause not known but H2S toxicity probable cause. Initial symptom consist of yellowing followed by rapid firing (Necrosis) of upper leaves. Plants turn necrotic and die in advance stages, with a rotten egg scent (H2S) evolved from the soil before drainage.(D. Marlin Brandon, California Rice Experiment Station, Biggs, CA)

Molinate phytotoxicity symptoms
Molinate phytotoxicity symptoms on water-seeded rice in California shown on right side of slide and normal (unaffected rice) on left side of slide. Molinate applied early in season when rice was in third leaf stage. Symptoms consist of dying of older leaves and dark green, brittle, and deformed growth from crown of plant. Affected plants in the early tillering stage show an open center with main stem missing and profuse titlering. Affected areas take on a a lighter green color. (D. Marlin Brandon, California Rice Experiment Station, Biggs, CA)

Phosphorus deficiency and response to topdressed P at rates of 30, 90, and 120 lb P2Os/acre at early tillering stage of water-seeded rice in California. P deficiency symptoms consist of chlorosis of older leaves with newer leaves a bluish, gray-green color. Chlorotic older leaves rapidly become necrotic and plant tillering is reduced greatly with only moderate reduction in height.(D. Marlin Brandon, California Rice Experiment Station, Biggs, CA)

Potassium_deficiency
Potassium deficiency
Potassium deficiency in small plot and main plot basin with adequate K (80 lb K20/acre) next to -K small plot. K deficiency symptoms consist of a reddish brown color of the upper leaves caused by small rusty brown spots on the leaf tips and down the leaves as shown in the -K treatment and main plot basin. Plant height is reduced and maturation accelerated slightly when K is deficient. Symptoms develop in late boot to heading stage.(D. Marlin Brandon, California Rice Experiment Station, Biggs, CA)

Rice_Blast_Disease
Rice Blast Disease
Rice Blast Disease caused by Pyricularia grisea on highly susceptible California rice variety S-201 in Louisiana. Resistant variety shown on left. Early leaf symptoms consist of a characteristic diamond shaped lesion with a gray or white center and a brown or reddish brown border. Newly formed lesions have a white or gray-green center and a darker green border. Shape, color, and size of lesions vary depending on varietal resistance, plant age, and lesion age. Typical brown "collar rot", and "neck rot" or "rotten neck blast" in the neck node also are typical symptoms of this disease. Highly susceptible rice varieties may have their leaves become necrotic and the plants die in the mid to late tillering stages.(D. Marlin Brandon, California Rice Experiment Station, Biggs, CA)

Sheath_Blight_Disease
Sheath Blight Disease
Sheath Blight Disease on Lemont rice variety in Louisiana caused by Rhizoctonia solani. Initial symptoms consist of large oval spots on leaf sheaths and oval to rectangular spots on leaves. Infection usually begins in late tillering to internode elongation stage and lesions have grayish white or light green centers with reddish-brown margins. Infection begins slightly above the water line on the plant and spreads up the plant as the plant matures. Infection occurs rapidly up to the flag leaves, after heading and areas of the field where infected areas coalesce with other infected areas may cause large areas of lodged, dead, and dying plants.(D.

Straighthead Diseases
Straighthead Diseases of Rice in Louisiana (Var. Mars) caused by arsenic, H2S, and unknown causes. It is referred to as a Physiological Disorder and occurs frequently in the Southern U.S. on lighter textured soils but not usually on heavy clay soils. This slide shows field symptoms that consist of sterile, parrot beak-shaped florets and darker green plants at maturity. The lighter colored golden rice in the wheel marks is the only rice that set seed and appears normal.(D. Marlin Brandon, California Rice Experiment Station, Biggs, CA)
Sulfonylurea_(Oust-r)_phytotoxicity
Sulfonylurea (Oust(r)) phytotoxicity
Sulfonylurea (Oust(r)) phytotoxicity to rice is seedling stage in Louisiana. Phytotoxicity symptoms consists initially of clorosis of leaves followed by rapid necrosis of older leaves and necrotic spots on all leaves. Many plants die with some surviving that are characterized by emergence of abnormal leaves and stem from the crown of the plant.(D. Marlin Brandon, California Rice Experiment Station, Biggs, CA)

Sulfonylurea Phytotoxicity Symptoms in rice in Louisiana. Symptoms in advanced stage consist of necrotic leaves and stems of plants (dead) severely effected, with new emergence of leaves and stem from crown of plants less severely effected. New growth is twisted and abnormal with less vigor and height of plant.(D. Marlin Brandon, California Rice Experiment Station, Biggs, CA)
