      Once the crop is matured or fully ripen, they are cut and gathered (Reaping) which are collectively called as harvesting. Harvesting depends on many factors like season, crop variety, maturity period, etc. Over-irrigation, irregular sunlight can prolong ripening of crop which thus delays the harvesting time. Early harvesting causes loss of. FARMDATA is an online system for tracking and reporting crop production data, particularly for organic vegetable growers. The system can be used for keeping records on seeding, transplanting, harvest, cover crops, compost, fertilization, irrigation, pest scouting and spraying activities, packing, distribution and customer invoicing.

        Although no exact estimates of total crop loss in India due to insects, diseases and weeds could be found, it is generally believed that on farm yield losses could range between 10–30%. In terms of monitory value, the losses due to these biotic factors account to near US$12 billion. Plants may be considered pests, for example if they are invasive is no universal definition of what makes a plant a pest. Some governments, such as that of Western Australia, permit their authorities to prescribe as a pest plant "any plant that, in the local government authority's opinion, is likely to adversely affect the environment of the district, the value of property in the Missing: Kerala.

Exotic plant pests are capable of damaging our natural environment, destroying our food production and agriculture industries, and some could change our way of life. Rationale and concepts of crop loss assessment for improving pest management and crop protection. Measurement of disease and pathogens. Measurement of insect pest populations and injury. Modeling of crop growth and yield for loss assessment. Disease progress curves, their mathematical description and analysis to formulate predictors for loss equations.

Besides the crop losses, rodents inflict severe damage to perennials such as fruit and plantation crops, afforestation plantations, and range/grasslands. In exhaustive reviews on rodent damage, Sridhara and Tripathi () reported that apple, peach, pecan and plum experience 17–40%, 2–7%, –% and 1–2% rodent damage, respectively in Himachal Pradesh.

Crop Losses to rodent pests in Kerala: A pre-harvest survey in select crop fields and survey on grain storage losses (Abstract) Punnen Kurian* The situation in Kerala is not different from the rest of the world; may be it is even worse.

Thus, despite the increase in chemical use, crop losses from insect pests, diseases, and weeds ranged between 5 and 10 % in wheat, 25 % in sugarcane, and 50 % in cotton (before the introduction of. seasons influence not only crop planting schedules but also rodent breeding, mortal-ity and mobility.

Successful damage control programmes have identified these seasonal trends and used the information to help de-termine when crops are most susceptible to damage and when rodent pests are most sus-ceptible to control.

Climate change and status of insect pests of vegetable crops in India Over the past years, annual rise in temperature with an average of 0 C, along with warming during post monsoon and winter season has led to exacerbation of pest problems like: Helicoverpa armigera: Vegetables, pulses and seed crops Spilosoma obliqua: Oilseeds and.

About % of the annual crop yield in India gets wasted because of pests, according to P.K. Chakrabarty, assistant director general (plant protection and biosafety) of the Indian Council of.

Rodents cause immense losses to agricultural production globally. Of the living rodent species in the world, species occur in India. However, only a little over a dozen species are regarded as pests in field and commensal situations.

Losses caused by rodents vary from crop to crop, season to season and in different agro-climatic by: 1. Crop losses to pests must be reduced in ways that are compatible with sustainable production, which requires pest control to be approached in a holistic manner with a focus on the entire agroecosystem.

Key to averting or minimizing crop losses to pests is a commitment, by government or other entities, to collect the data, Author: Thomas Culliney.

Distribution, nature of damage, life history of important key pests of crops and their management strategies are outlined hereunder. Economic losses per unit area (US$/ha) (Table 1) were estimated by dividing the economic losses caused by insect pests obtained for each crop by planted area.

The mean percentage of losses in production for all crops was obtained by multiplying the total loss in production by divided by the total yield of Size: KB.

They cause substantial economic losses and reduce food security at household, national and global by: Despite the impressive achievements and even greater potential in minimizing pest- related losses, only a handful of books have been published on the topic of host-plant resistance to insects.

This book fills this wide gap in the literature on breeding insect- resistant crops. Farmers lose an estimated average of 37% of their rice crop to pests and diseases every year. In addition to good crop management, timely and accurate diagnosis can significantly reduce losses.

First is direct injury done to the plant by the feeding insect, which eats leaves or burrows in stems, fruit, or roots.
