Five (5) abiotic or environmental factors affecting the growth of plant pathogens prior
to disease infection ;
1.Temperature,pressures
1.1 Some archaebacteria require very high temperatures,or pressures,or unusual concentrations of chemical substances such as sulfur,because of their specialization into extreme condition.
1.2 Plant are harmed when they are exposed to extremely high temperatures or low temperatures for a long period of time.This may lead to scorching leaves and sunscald fruits due to high temperatues or sunburn.
1.3 Low temperatures may lead to damage to sensitive plant parts like leaves,buds,fruits,etc.
1.4 Cold temperatures may also kill the entire plant.
2.Water
2.1 Some plants are mostly water starved,so himidity plays a larger role in their biology.
If there is too much moisture content in water or too less water, it may lead to damage to the plant.
2.2 Too much water in soil due to flooding, too much watering,poor drainage can lead to yellowing of leaves and stunted plant growth.
2.3 Excessive moisture in soil may lead to lack of aeration.This causes damage to the root system leading to root rots and damping-off of seedlings.
3.1 Plants require many major and minor elements for growth. Major elements include phosphorus, calcium, magnesium, nitrogen, etc. While minor elements include iron, boron, copper and zinc. When the plant suffers from deficiencies of either of the minerals, it leads to interruption of essential plant functions, leading to death of the plant. Thus, one has to feed the plant with fertilizers and nutrients to prevent deficiencies.
4.Soil
4.1 Any change in soil pH will lead to growth problems, toxicity symptoms and even mineral deficiency.
4.2 High pH or low pH are unfavorable for plant growth. If the soil pH is not corrected soon, it could lead to
plant death.
5.Light
5.1 The sun is the major energy source of nearly all ecosystems.Availability of light can determine habitat
5.2 If the plant receives low light intensity, it causes a number of problems like etiolation,
In etiolation, the plant growth is poor and lanky along with chlorotic foliage.
