Crop Pests and Diseases Control Methods

10 Questions

Match the following seed certification requirements with their descriptions:

Minimum germination rate of 85% = Percentage of seeds that must sprout under specified conditions Purity rate of 98% = Percentage of pure seeds in the batch Treated with fungicide/pesticide = Protection against diseases and pests during germination Advantages of certified seeds = High germination rate guaranteed, increased profits, less qualitative issues

Match the following advantages of winter sowing with their descriptions:

Easier for farmers undergoing mixed farming = Suitable for farmers involved in both livestock and tillage Allows work to be spread out throughout the year = Facilitates better time management for farmers Increased profits due to longer growing season = Higher earnings due to extended period for crop growth Advantages of crop rotation = Prevents pest build-up, maintains soil nutrients and structure

Match the following descriptions with their explanations:

Nutrient management = Rotation of crops helps prevent nutrient depletion in soil Common pests, weeds and diseases = Leaf Blotch is a fungal disease spread by rain Definition of crop rotation = System of tillage rotation to prevent pest build-up and maintain soil health Advantages of seed certification = Ensures high-quality seeds with specific germination and purity rates

Match the following crop pests with their corresponding larvae:

Leatherjackets = Crane fly larvae Wireworms = Click beetle larvae Powdery mildew = Fungal disease Leaf rust = Fungal disease

Match the following diseases with their types of control methods:

Powdery mildew = Fungicide Barely dwarf virus BYDV = Direct control Leaf rust = Fungicide Wireworms = Pesticide

Match the following chemicals with their mode of action:

Contact herbicide = Can only affect plant if it comes in contact with it Translocated herbicide = Chemicals absorbed by roots and translocated to stem, leaves & flower Contact fungicide = Can only affect fungi if it comes in contact with it Systemic fungicide = Similar to translocated herbicide

Match the following types of chemicals with their targets:

Herbicide = Plants Fungicide = Fungi Pesticide = Pests Bait = Rats, slugs, etc.

Match the following descriptions with their corresponding control methods:

Diligent spraying is important here. = Contact herbicide Very effective. = Translocated herbicide Liquid spray and very similar to herbicides. = Contact fungicide Works by ingestion of chemical by pest. = Pesticides come in solid, liquid or gaseous form.

Match the following terms with their definitions:

Herbicide = A chemical that kills plants or inhibits their growth Fungicide = A chemical that kills or inhibits the growth of fungi Pesticide = A chemical used to kill pests Bait = Used to kill rats, slugs, etc.

Match the following diseases with their symptoms:

Powdery mildew = Turns underside of leaves yellow Leaf rust = Causes premature death of leaves Barely dwarf virus BYDV = Transmitted by aphids

Learn about common fungal and viral diseases, as well as pests that can affect crops, and the different methods of direct control using chemicals. Understand how powdery mildew, leaf rust, Barely dwarf virus BYDV, leatherjackets, and wireworms can impact crop yield.
