What is the difference between abiotic and biotic diseases?

Biotic diseases sometimes show physical evidence (signs) of the pathogen, such as fungal growth, bacterial ooze, or nematode cysts, or the presence of mites or insects. Abiotic diseases do not show the presence of disease signs.

What diseases affect wheat crops?

Cereal cyst nematode, take-all, rhizoctonia root rot, crown rot and root lesion nematode are important cereal diseases that can cause significant yield loss.

What is the difference between rice and maize?

Maize wins in this category. Corn contains vitamin A, vitamin E, vitamin C, and vitamin K, whereas rice entirely lacks these vitamins. Corn is also richer in most B vitamins, such as vitamins B2 (riboflavin), B3 (niacin), and B5 (pantothenic acid) in particular, except for vitamin B9 (folate).

The average temperature required throughout the life period of the crop ranges from 21 to 37ยบ C. Maximum temp which the crop can tolerate 400C to 42 0C.

How do you differentiate abiotic and biotic in diagnosing plant disease What is the difference of two factors?

The infectious causes are classified as biotic (living) causes of plant problems. They include (but are not limited to) insects, mites, and disease pathogens. Environmental stresses, such as temperature injury and water or nutrient stress, are abiotic (nonliving) factors that may affect plant health.

What is biotic disease?

Biotic (infectious) diseases are developed owing to microbial infection, while abiotic (noninfectious) diseases are developed due to environmental factors. In this chapter, we are concerned with plant pathogens or phytopathogenic microbes such as bacteria, viruses, fungi, mollicutes, and so on.

canker, plant disease, caused by numerous species of fungi and bacteria, that occurs primarily on woody species. Symptoms include round-to-irregular sunken, swollen, flattened, cracked, discoloured, or dead areas on the stems (canes), twigs, limbs, or trunk.

What is wheat rust disease?

Rust diseases represent the most economically significant fungal diseases in wheat and other cereal crops worldwide, and they are widely distributed across wheat growing regions. With the capacity to form new strains of fungus, rusts can attack even previously resistant varieties.

What is the difference between wheat and rice farming?

Rice farming requires much more time and is much more labor intensive than wheat farming. Rice fields must be irrigated, which requires the sharing of water. Rice paddies are bordered by dikes and canals that require frequent maintenance, so farmers have to work together constantly and share resources.
