2.1 Краткое описание Технологии

Определение Технологии:

Reducing the use of common agrochemicals by supporting preferred habitats of biological pest control agents like amphibians and by using alternative self-made organic pesticides.

2.2 Подробное описание Технологии

Описание:

Irrigated crops attract various pest species. Farmers usually address crop pest and disease problems through the use of agrochemicals. Especially bees, birds, and amphibians, which fulfil important functions in agroecosystems, are affected by high use of agrochemicals. The combination of inappropriate irrigation practices, incorrect application rates of agrochemicals, and low producer prices often lead, however, to poor income from smallholder irrigated agriculture and to further problems such as poor health, loss of biodiversity, and soil and water contamination. Amphibians are themselves proven biological pest control agents of arthropod pest species (predators of e.g. larvae of butterflies, beetles, termites, bugs and others) and the incorrect use of agrochemicals, as well as the removal of vegetation along field margins hampers this useful function. The technology described here aims to support and utilise the potential of amphibians (such as frogs and toads) as biocontrol agents –as an alternative to agrochemicals in crops.

Purpose of the Technology: Establishing habitats for amphibians is crucial in order to increase and secure their numbers: for example encouraging shrubby vegetation next to water bodies for arboreal frogs, and installing additional water ponds inside and around plantations for ground-living frogs. First, the local species pool of amphibians needs to be determined by visual and acoustic observations. Amphibian species do not need to be determined precisely, but it is important to detect whether they are arboreal and/or ground-living amphibians, as these two groups have different roles as biocontrol agents. Pests that feed on the main cultivated species should be characterized by (a) collecting plant material to determine the type and quantity of pests and (b) by comparing observations with neighbouring farmers and extension agents. Pest species can be determined also by installing traps and using nets. Inspection should be done at least every 15 days to once a month during the whole rainy season to detect possible mass reproduction of arthropods after rainfall events. Once amphibians and pest species are detected, decisions on management strategies can be made. Such a strategy is to create habitats for amphibians with additional sources of income, e.g. by planting pomegranate or guavas as shrubby vegetation structure for arboreal frogs. If pest species can't be reduced solely by amphibian species, the use of agrochemicals has to be reconsidered. Preference shall be given to chemicals which do not harm amphibians. Organic, self-made pesticides based on the extract of manioc roots (manipoera) seem promising. Twenty litres of manipoera, the bark of manicoba tree (Manihot pseudoglaziovii), a cup of American wormseed (Dysphania ambrosioides), a cup of yellow tagetes (Tagetes sp.), a cup of malagueta pepper (Capsicum sp.), garlic and a little bit of bleach have to be chopped, mixed and fermented for 10 days. Application of the final product (25 ml of organic pesticide diluted in 20 l of water) should be done every 8 to 15 days depending on crop species.

Natural / human environment: Increasing habitat heterogeneity stimulates the diversity of amphibians and so a greater number of pest types will be controlled. Combined control by safeguarding natural amphibian habitats and application of organic pesticides is an innovative alternative to the overuse of toxic agrochemicals.

Пояснения:

Major land use problems (compiler’s opinion): Intensive livestock grazing pressure, agriculture and logging of native vegetation are the driving factors behind loss of the Caatinga dry forest. The high use of agrochemicals additionally pollutes soils and watersheds, and probably also decreases local biodiversity. Droughts seem to occur more frequently and these decrease water and food availability for livestock, as well as affecting the local fauna.

Example for establishment of technology within study region: In the irrigation schemes of Petrolândia, Pernambuco, Brazil, the most important arthropod pest species in banana plantation was a weevil (Curculionidae, Coleoptera). The weevil (so called “moleque da bananeira”) attacked the roots of the banana plants, in consequence the plant tumbled down and was lost. As the weevil stays during the day in the ground and only starts moving during the night, it is difficult to combat this pest species by agrochemicals. With an increase of small water ponds with a shore vegetation structure (for example at 2 corners of the plantation) the abundance of ground-living amphibians increases and so the presence of amphibians in the banana plantation which feed on the weevil during the night.

Major land use problems (land users’ perception): Droughts and consequently problems of feeding livestock on natural vegetation (lack of fodder and grazing grounds), deforestation, extensive and inappropriate use of agrochemicals, low producer prices.

Пояснения:

To calculate the above example a scenario with maximum activities was taken. Any other scenario will be cheaper. Prices are from the year 2013. Real 1 = USD 0.3.. A total of 6 liters of concentrated organic pesticides per hectare per year are needed. This applies for both self-made and commercial pesticides. As commercial organic pesticides cost about USD 36 per liter, farmers spend USD 216 less per year for self-produced organic pesticides. Similarly commercial non-organic pesticides are more expensive compared to self-made organic pesticides. An additional income of USD 120 / ha / harvest were estimated for guava trees even under possible poor conditions like shadow and extensive management. Other additional sources of income are from the sale of self-produced organic pesticides and livestock grazing instead of using herbicides.

Пояснения:

As amphibians depend in their abundance and species composition on the rainfall amount and intensity the technology is sensitive for changing rainfall events by increasing abundance of amphibians with higher rainfall amount and so probably a better pest control.
In case of frequent droughts, reptiles like lizards get more important as they do not depend so strong on rainfall events like amphibians.

6.7 Сильные стороны/ преимущества/ возможности Технологии

Сильные стороны/ преимущества/ возможности по мнению составителя или других ключевых специалистов
A strong advantage is the low cost of this ecosystem service which is provided almost freely to farmers, especially when the potential for pest control (abundancy of useful amphibians) is high enough to eliminate the need for agrochemicals. How can they be sustained / enhanced? Establish adequate habitats to maintain high diversity of the relevant reptiles and amphibians.
Less use of agrochemicals results in a healthier environment for producers and consumers How can they be sustained / enhanced? If the potential of the reptiles and amphibians is not high enough to combat all pest species, organic chemicals or alternative biocontrol species could be used (for example horntails etc.).
Changing monoculture to mixed systems - or even agropastoral systems - offers additional income sources, while diversification often as a buffer to sudden drops in the price of a particular crop How can they be sustained / enhanced? The crop mixture needs to be well designed, to ensure that the harvests of important crops are not affected too much, and the reduction compensated for by the others.
