Evaluation of Fruit Bagging as a Pest Management Option for Direct Pests of Apple
Published in Insects
Bagging fruit with plastic, paper, and two-layer commercial bags was evaluated for control of insect pests and diseases in an experimental apple orchard planted with ‘Red Delicious’ trees. Results from fruit damage evaluations at harvest showed that bagging significantly reduced fruit damage from direct apple pests compared with non-bagged control ...
Transition by head-on collision: mechanically mediated manoeuvres in cockroaches and small robots
Exceptional performance is often considered to be elegant and free of 'errors' or missteps. During the most extreme escape behaviours, neural control can approach or exceed its operating limits in response time and bandwidth. Here we show that small, rapid running cockroaches with robust exoskeletons select head-on collisions with obstacles to main...

Optimum Weed Control Method Increases the Yield of Kinnow by Improving the Physical Properties of Soil
ABSTRACT: Going towards sustainable fruit culture, it is very important that soil fertility should maintain by adopting the proper weeds control and adding the organic matter. This research was carried out to identify the most suitable weed control method for Kinnow orchard. The plants of Kinnow at the age of 6 years grown under drip irrigation wer...
Why RLC Realizations of Certain Impedances Need Many More Energy Storage Elements than Expected
It is a significant and longstanding puzzle that the resistor, inductor, capacitor (RLC) networks obtained by the established RLC realization procedures appear highly nonminimal from the perspective of linear systems theory. Specifically, each of these networks contains significantly more energy storage elements than the McMillan degree of its impe...
Agronomical indicators and incidence of insect borers of tomato fruits protected with non-woven fabric bags
ABSTRACT: Fruit bagging is an efficient mechanical control technique used in fruit growing. However, to date, few studies have evaluated the efficacy of bagging in the cultivation of vegetables, including tomato crops. The objective of this study was to evaluate the effectiveness of bagging of tomato flowers and/or fruits using a non-woven fabric (...
Evaluation of the Impact of Weed Control Methods on Quantitative and Qualitative Characteristics of Moldavian Balm; A Me...
Published in Acta Technologica Agriculturae
Moldavian balm is an annual herbaceous plant and its lemon-scented leaves contain essential oil. However, weeds adversely affect its growth by release of allelochemicals, and/or direct competition for nutrient, moisture, light and space. Current experiment was conducted to evaluate the different weed control methods including preventive approach (s...
Reduction of population numbers of Melolontha spp. adults – a review of methods
Published in Folia Forestalia Polonica
The article provides information about control of Melolontha spp. adults, the methods used in the past, chemical pest control as well as treatments applied today. In old times, cockchafer populations were reduced mechanically, by manual collection during the swarming period or by covering soil surfaces to prevent egg lying by females. Chemical pest...
Case studies best practices onkruidbestrijding : Duurzame onkruidbestrijding op laanboombedrijven in Rivierenland
Onkruid is in de laanboomkwekerij een groot probleem. De mogelijkheden voor chemische onkruidbestrijding nemen af en mechanische onkruidbestrijding op klei is moeilijk en door het wisselende weer niet altijd toepasbaar. Toch streeft de laanboomsector in de regio naar duurzame oplossingen. Welke methoden zijn er en worden op dit moment al succesvol ...
