## 1 Introduction  
According to the Food and Agriculture Organization of the United Nations (FAO), it is estimated that the world population will increase by over 32% by 2050, which will mean an increase in the demand for food [1]. This fact highlights the need to adopt strategies that ensure the efficiency, productivity, sustainability, and security of our food supply. One of the challenges to achieve these goals is the control of pests affecting crops, which, in recent times, have increased due to globalization, climate change, and the emergence of resistance to conventional pesticides [2, 3]. Among the pests that most severely affect crops, fungal infections via ascomycetes, such as _Botrystis cinerea_[4], _Fusarium oxysporum_[5], and _Alternariaalternata_[6], have a great impact worldwide. In Brazil, _B. cinerea_ affects several crops, mainly eucalyptus in the southwest region [7], and grapes [8] and strawberries [9] in the south. Recent studies show that some strains of this fungus are resistant to some commonly used fungicides such as external quinone inhibitors (QoI) [10]. Moreover, _F. oxysporum_ causes banana Fusarium wilt, a pandemic that has threatened crops and the export of this fruit in Brazil, which is the fourth largest banana producer in the world [11; 12]. Regarding Alternaria brown spot caused by _A. alternata_, this affects mainly tangerine crops, in which Brazil is the fifth largest producer [13]. Moreover, there are few fungicides registered in the country that are able to control the spread of this fungus, and there is evidence of the emergence of resistant strains of this pathogen [10]. Furthermore, the golden twin-spot moth, _Chrysodeixis chalcites_ (Esper) (Lepidoptera: Nocutiidae), is a highly polyphagous species that causes severe damage to crops in many regions of Europe, the Mediterranean, the Middle East, and Africa [14]. The larvae of this moth feed on several crops, such as bananas, cabbages, beans, corn, potatoes, or tomatoes [15]. Moreover, _Chrysodeixis includens_ is a pest that affects crops in North and South America, especially in the USA, Argentina, and Brazil. In Brazil, the insect is one of the major defoliators of soybean crops, especially relevant as the country is the world's leading soybean producer and exporter [16]. Currently, crop protection relies almost exclusively on the use of synthetic pesticides [3]. However, their indiscriminate use [17] has aroused social concerns due to overwhelming evidence of their detrimental effects on the environment and human health, increasing the risks for the development of resistant strains and the erratic supply of beneficial organisms [18]. Therefore, there is a need for research on eco-friendly pesticides for their use in agricultural pest management programs. Botanical biopesticides are considered as safe, ecologically sound, and sustainable alternatives to synthetic pesticides [19; 20]. They have key advantages over traditional pesticides, including lower toxicity, they are easily biodegradable, they exclusively affect the pest in question and closely related species, they present new modes of action, and can be used in organic agriculture [21; 22; 23]. In fact, several plants and plant-derived products have been reported as botanical biopesticides [24; 25], and pure natural products such as Azadirachtin and pyrethrins are the basis of most current, commercial botanical insecticides [19]. The sapindaceae family comprises about 140 genera and 1900 species, distributed mainly in tropical regions of the world. In Brazil, the family is represented by 28 genera and 417 species [26]. _Magonia pubescens_ A. St.-Hil. (Sapindaceae) is an endemic species from Brazil popularly known as 'tingui' or 'timbo'. It is the only species of the _Magonia_ genus and is widely distributed in the states of Goias, Mato Grosso, Mato Grosso do Sul, and Minas Gerais [27] in the Brazilian savannah (the Cerrado) [28].
